1. usb power supply via j79 2. external dc (ext dc) power supply via power jack j78 or battery via j77 3. three separate power supplies (vdd , vio, vmcu) via terminal block j76 the evb has three supply rails: vdd, vio, and vmcu. vdd and vio are routed di rectly to the daughtercard to power the vdd and vio pins on the si47xx chip, while vmcu is used to power the baseboard. the external dc power supply and battery should not be connected simultaneously. refer to section 9. "using the evb with a 9 v battery?" on page 109 for more information. usb power supply & ext dc power supply switch sw1 is used to select between the usb power supply and ext dc power supply. the usb power supply or the ext dc power supply ca n be configured in one of the following two modes: 1. fixed +3.3 v 2. adjustable vdd and vio fixed +3.3 v only one ldo is used in this mode which outputs a

software revision number is available under help ? about. the gui software development prog ram uses a host machine usb port to communicate wit h the si47xx evb and is tested for use with windows xp, windows 2000, and windows 7. to install, insert the silicon laboratories si47xx cd into the host machine cd drive and launch windows explorer. open the cd to explore the contents in a window like the one shown in figure 23. figure 23. installation and setup screen important : open and read the readme.doc file at this point. it may contain information that is not captured here, and which could be very important to the functionality of the evb or software. run the setup.exe and follow the instructions on the screen. note: if you get this error message: "this setup requires the .net framework version 4.0," then you should install the .net framework that is provided on the cd and re-run the setup. the gui requires ve rsion 4.0; however, multiple versions such as 2.0, 3.0, and 5.0 c an be installed simultaneously. after installation is finish ed, a silicon labs audio gui icon will appea r on your desktop. launch the software by clicking this icon on the desktop as shown in figure 24. figure 24. launching the gui si47xx-evb rev. 0.8 33 4.2. board initialization after launching the gui, you will be shown the initialization window as shown in figure 25. note: this window can be accessed at any time by choosing in itialize from the file menu from the main gui screen. figure 25. gui initialization screen 4.2.1. board selection at the top of the initialization window there is a board selection box, as displayed in figure 26, that allows the selection of the board that will be cont rolled by the gui. this box is popu lated automatically and will update real time as boards are connected/removed from the pc. if no evbs are list ed in the board selectio n box, verify that an evb is connected to the usb port of the pc running th e gui application. after selecting the desired bo ard the gui will populate the rest of the di alog with options appropr iate to the board selected. you will only see modes/ options for the type of board that is currently selected. figure 26. board selection box si47xx-evb 34 rev. 0.8 4.2.2. board discovery bus mode the initialize process can be configured to use either 2-wire or 3-wire bus mode. this can be configured by selecting file ? board discovery bus mode. this feature is useful when using th e silabs evb and gui to control a protot ype that is designe d to use one bus mode only. 4.2.3. function configuration for each mode availabl e on the selected evb, multiple configuration items (f igure 27) will be pr esent to allow for configuration of the gui software. it is possible to change these settings to meet testing requirements. the default configuration of the board when you connect it to the computer is acceptable for most users. after initialization, the gui will save and restore these settings wh enever the same type of board is connected. figure 27. mode configuration items 4.2.3.1. functions currently the ui supports four possible functions. thes e functions are am receiver, fm receiver, wb receiver, and fm transmitter. each function is configured independently from other functi ons. it is important to configure all functions as desired as it is possible to have fm re ceive boot in digital mode while am receive boots in analog mode. the currently highlighted function row will be the function that is initialized wh en the initialize bu tton is selected. settings for other functions th at are not selected will be sa ved and used to initialize th at function when choosing another function from the ui main window. 4.2.3.2. boot mode there are two boot modes possible for each function. it is possible for some boot modes to not be available on some boards. ?? from device?this option will use the fi rmware embedded on the device selected. this is the faster of the two options. ?? from file?this option will use the patc h functionality of the device to send firmwa re from a file stored within the ui to the device. if using this option, choose the appropriate firmware in the firmware column for the function you are configuring. si47xx-evb rev. 0.8 35 4.2.3.3. default mode there are two or more default modes possible for each function. ?? use last ui state: when selected, the gui will restore a ll settings on the device to the previous settings configured in the gui the last time it was closed. ?? use chip defaults: when se lected, the gui will use the settings that were default in the firmware on the device. only properties related to the correct setting of rclk (such as frequency and prescaling) and initial tuning (such as frequency) will be change d. if an error occurs dur ing initialization of a function, choose this setting to default the gui settings back to the chip defaults. ?? saved configuration states: if you have previously sav ed or imported any configur ation states, they will be listed by name. when one of these is selected, th e gui will restore all settings on the device to the previously saved settings. 4.2.3.4. audio mode this option allows the user to change between analog or digital modes if the board connected supports digital. sections 2.1.4, 5, 6, and 7 each document the possible settings in more detail depending on what function is being configured. figure 28 displays the window after the details button ha s been pressed which helps with selection of the audio mode by displaying a bitmap of the current audio setting in the dialog. figure 28. expanded details dialog 4.2.3.5. firmware this selection is only required if "fro m file" was chosen for the boot mode. use this setting to choose which firmware will be

setting affects all functions that are configured. it allows the device to be booted either in 2-wire or 3-wire mode. 4.2.3.7. internal oscillator when the "use xoscen" is enabled and the board is configured to use the crystal oscillator, the gui will boot the device using the crystal oscillator. this option is only av ailable on devices th at support the crys tal oscillator option. 4.2.3.8. auto boot when ui opened and only one board is connected when this item is selected, the gu i, when launched, will automatically bo ot the board if the same board is connected. if more t han one board is connected, th e gui will display the initializatio n dialog to allow selection of the board to initialize. 4.3. switching functions after the board has been properly configured for all functions it is possible to switch between functions from the main ui window using the function butto ns provided. only function buttons will appear for the functions supported by the device currently running. figure 29 highlights the buttons used to switch functions from the main screen. figure 29. function switch buttons si47xx-evb rev. 0.8 37 4.4. state management once the part has been initialized, a state management option becomes available in the file menu. this gui feature allows the user to save, retrieve, load, and delete the configuration state which contains the property values. 4.4.1. save configuration state to save the current configuration state, select file ? state management ? save current state. the select configuration window shown in figure 30 will pop up. enter a name for the co nfiguration state and click ok. the current state that contains the property values is now sa ved under the given name. if a state already exists with the chosen name, the gui will give you t he option of replacing the original state, entering a different name, or canceling the save. figure 30. naming a configuration state during save 4.4.2. retrieve configuration state once a configuration state for a part has been saved, it will appear in the de fault mode list in the initialization window as shown in figure 31. select th e state you wish to retrieve when initializing the pa rt, and all properties and the tuning frequency of the saved configuration will be restored. figure 31. saved configuration state si47xx-evb 38 rev. 0.8 4.4.3. load configuration state when a configuration state for a part has been saved, it will al so appear in the load state list as shown in figure 32. select the state you wish to load, and all proper ties and the tuning frequency of the saved configuration will be restored without doing initialization to the chip. figure 32. loading configuration state 4.4.4. delete configuration state to discard a saved configuration state, select file ? state management ? delete state. the de lete configuration window shown in figure 33 will pop up. sele ct the configuration state you want to delete from the list and click ok. the deleted configuration state will no longer be available in the default mo de list of the initialization window or available for export. figure 33. selecting configuration state to delete si47xx-evb rev. 0.8 39 4.4.5. export saved state in addition to saving, retrie ving, and deleting the configur ation state, the gui also gi ves the end user the ability to export the configuration state to a file. the file can th en be imported to installations of the gui on different machines to allow multip le users to easily implement the same configur ation state. to export a saved configuration state to a file, select file ? state management ? export saved state and the sele ct configuration window will pop as shown in figure 34. select the configuration state to expo rt and click ok to save the configuration file with a .ini extension. this configuration file can now be exported to different machines. the name of the saved state is retained in the file when exported. figure 34. selecting configuration state to export 4.4.6. import saved state a saved configuration state can be imported from a .ini f ile exported by another instanc e of the gui. to import a saved state, select file ? state management ? import state file, then browse for and select the desired file. once the file has been imported, th e saved state will appear in t he default mode list in the init ialization window. if a state already exists with the same name as th e state in the imported file, the gui w ill give you the option of replacing the original state, choosing a new name for the imported stat e, or canceling the import from file. the name appearing in the initialization window will not necessa rily be the same as the *.ini file name exported. it will reflect the name of the original state that was exported. 4.5. disconnecting the evb the gui provides three methods for disconnecting the de vice: closing the gui, choosing disconnect from the file menu, or physically disconnect ing the device from the pc. when closing the ui or selecting disconnect from the file menu, the gui will prompt if the device should be powered down or not. this prompt allows for furthe r investigation of the device after the gui has been disconnected from t he evb. after the board has been disconnected through the file menu, the gui will save the current state of the device to disk. th is state will be used to power up the de vice in the same state next time the board is connected. the gui will only save the current state if the board is disconnected through the file menu or the gui application is closed. if the board is removed from the pc without being disconnected through the file menu and before the gui is closed, then all state data will be lost. si47xx-evb 40 rev. 0.8 5. fm transmitter

to receive digital audio input at pins 13 and 14 (din and dfs), but the user still provides an analog audio source to the evb. it is useful for a user who wants to test digital input on the si47xx but does not have a digital audio source. the analog audio so urce is converted to digital audio through the codec, which can be configured to output various digital audio formats. refer to figure 41, ?codec settings property window,? on page 49 to control the codec. configure the desired parameters in the initialization screen and then click initialize. a new window displaying "initializing fm

transmit window descriptions item description si47xx-evb rev. 0.8 55 there are 16 different group types in the rds/rbds standard, and for every group the following information is always transmitted: 1. program identification (pi) 2. program type (pty) the gui makes it easy to send data in three of the following group types: 1. group type 0: program service (ps) 2. group type 2: radio text (rt) 3. group type 4: clock time (ct) it is possible to send data in the other group types, but the user has to manually enter the data in hexadecimal code. because of the complexity of the rds/rbds standard, the explanation of the rds transmit data window is divided into three sections: basic, intermediate, and advanced. si47xx-evb 56 rev. 0.8 5.10.1. basic the rds transmit window is divided into three categories: 1. general 2. program service 3. buffers in the basic section, we will cover two out of the three categories : the general and program service. in the general category, the user can set the pi and pty data. in the program service, the user can set the ps data (group type 0). the following diagram shows a step-by-step explanation: figure 46. basic rds message illustration 1. first select whether you want to transmit in rds format (europe) or rbds format (us). 2. type in the program id entification in this field. program identi fication is a 16-bit code assigned to an individual station. 3. select the program type in the pull down menu he re. some examples include news, information, sports, talk, rock, etc. 4. enter the program service (ps) in the boxes provided. you can enter a maximum of 12 different ps messages, in which each ps message can contain a maximum of 8 characters. a. repeat count: enter how many times you want each ps message to be tr ansmitted before sending the next ps message. b. message count: enter how many of the 12 ps messages that you actually want to transmit. c. mix: select 100 percent. 5. click send message button here. now the rds will transmit the ps message al ong with the pi and pty. you should see these data in your rds receiver. 2 3 4 1 5 si47xx-evb rev. 0.8 57 5.10.2. in termediate in the intermediate section, we will cover th e buffers category of sending the rds data with the device, in particular we will send group type 2 (radio text ) and group type 4 (clock time). the following diagram shows a step-by-step procedure to send the buffers data in addition to the general and program service data covered in the basic section. figure 47. intermediate rds message illustration 1. select the mix percentage that you want between transmitting the data in program service and the data in the buffers. a mix percentage of 100% means that you will always tran smit the ps message regardless of what is contained in the buffers, whereas a mix percentage of 0% m eans that you will always transmit the data in the buffers regardless of what is contained in the ps. if the buffers are empty, the ps messages will be transmitted all the time regardless of the mix percentage. 2. enter the radio text message that will be transmitted. after entering t he rt message, clic k either the "add to circular" button or the "add to fifo" button. the rt message will be encoded according to the rds group type 2 rule. a. clicking "add to circular" button means that yo u add the rt message into the gui circular buffer queue. note that the message itself has not been uploaded into the circular buffer inside the device until the clear buff & send is clicked. b. clicking "add to fifo" means that you upload the rt message into th e gui fifo buffer queue. note that the message itself has not been uploaded into the fifo buffer inside the device until the clear buff & send is clicked. 3. enter the size of the fifo that you want here. the device buffer has a total of 128 blocks, which is shared by the circular buffer and the fifo. therefore, the circ ular buffer size (shown in 3a) will be the remainder of the 128 blocks minus the fifo size. 4. clicking this "clear buff & se nd" button will upload the message from the gui ci rcular buffer queue into the circular buffer inside the device . the circular buffer on the part will repeatedly send the message contained in the buffer. note that the messages in the circular buffer will be transmitted only if the ps mix 2 3 4 1 5 3a 6 si47xx-evb 58 rev. 0.8 value is set to anything other than 100%. 5. clicking the "add time" button here will add the current time as a rd s group type 4 message to the gui fifo buffer queue. 6. clicking the "clear buff & se nd" button will upload the me ssage from the fifo bu ffer indicator window into the fifo buffer inside the de vice. the fifo buffer on the part will only send the messages contained in the buffer once. a good example of using fifo buffer is when you want to send the time data. time is something that occurs only on ce, so it will not be beneficial to upload time to the circular buffer and transmit it continuously. refer to step 5 for information on se nding time data. note that the messages in the fifo buffer will be transmitted only if the ps mix value is set to anything othe r than 100%. 5.10.3. advanced in the advanced section, we will cover the remaining rds topics. figure 48. advanced rds sending illustration 1. dynamic: this tells whether t he pty code is static or dynamic. 2. alternate

artificial head: 0 = not artificial head; 1 = artificial head b. stereo: 0 = mono; 1 = stereo c. audio compressor: 0 = not compressed; 1 = compressed d. traffic program (tp): 0 = no tp; 1 = tp e. traffic announcement (ta): 0 = no ta; 1 = ta f. speech: 0 = speech; 1= music 4. a/b flag: this is an important flag in the rds group type 2 (rt). checking this box when a radio text is 2 3 4 1 5 6 7 8 9 si47xx-evb rev. 0.8 59 uploaded means that the rt is uploaded with the flag set. un-checking this box when an rt is uploaded means that the flag is not set. this flag tells the receiver that when the flag toggles from set to reset or vice versa, the receiver will clear the display before showing the next rt. 5. manual group entry: use this box to upload t he rds data manually. you can use this box to upload messages from the group type for which the gui does not have encoding support. for these messages, the user must encode the messages into hexadecimal code. 6. circular buffer indicator: this displays the me ssage that gets uploaded into the circular buffer in hexadecimal code. this can be useful to see how the group type 0 (ps), type 2 (rt), and type 4 (ct) is encoded into rds data. 7. delete circular buffer group: this deletes a gro up that is selected in th e circular buffer indicator. 8. fifo buffer indicator: this displays the message that gets uploaded into the fifo buffer in hexadecimal code. 9. delete fifo buffer group: th is deletes a group that is select ed in the fifo buffer indicator. si47xx-evb 60 rev. 0.8 5.11. fm transmitte r register map window the register

band scan selecting tools ? log band scan allows you to spec ify a filename and begin a scan of the entire band for rds data, rds acquisition times, and the contents of each regi ster. the scan feature starts with the first frequency in the band (chan = 0) and then seeks to the first station that meets the seek criteria (seekth, skcnt, sksnr). when a valid station is found, the software waits at the statio n for the time specified by view ? session preferences ? scan log after tune delay (sec) a nd then checks if rds is available. if rds is not available, the software logs the register settings and seeks to the next valid station. if rds is avai lable, the software waits an additional delay as specified by view ? session preferences ? scan log rds log delay (sec). when this delay expires, the software logs the rds in formation and register settings and seeks to the next valid station. while scanning, the software displays a green "scanning" notice below the menu bar. the scan can be aborted by selecting the tools ? log band scan a second time. when the scan completes, the filena me given is saved in comma separated format and is available for analysis in a text editor or spreadsheet. 6.10.2. log raw rds data selecting tools ? log raw rds data prompts for a filename in which all rds data will be logged in comma separated format. the software then logs all raw rds

si47xx-evb rev. 0.8 109 9. using the evb with a 9 v battery the evb can be used with a 9 v battery that a llows the user to disconnect th e board from th e computer for evaluating the si47xx. follow the guidelines lis ted below to use your evb with a 9 v battery. 1. put the switch sw1 in the ext/battery position. 2. connect a 9 v battery to jumper j77. 3. connect the usb cable. 4. launch the gui. 5. initialize the evb fo r am or fm reception. 6. once the desired station is tuned and all the settings for the receiver are according to the user's liking, please exit the gui. 7. when asked whether to leave the device on, please click on yes. 8. remove the usb cable. 9. the evb can now be moved around. note that once the evb is using its 9 v battery, it is not possible to change the tuned station. repeat steps 3?9 to tune the evb to a different stati on while running on the 9 v battery. si47xx-evb 110 rev. 0.8 10. debugging guidelines for si47xx evb table 28. debugging guidelines for si47xx evb mode symptom solution configuration evb not recognized ?? if the evb is not recognized by the pc, remove the usb connection and reconnect. ensure the evb is recognized by the pc by right-clicking on my computer and selecting properties ? hardware ? device manager. under human interface devices, select each hid-compliant device ? ?details entry and confirm one contains vid_10c4&pid_8244. ?? if the evb is not recognized by th e gui, but is recognized by the pc, it is likely that another process has erroneously acquired the handle to the evb. two processes known to ca use this issue are lxhidsve.exe and eausbkbd.exe. te rminate these processes in the task manager. ?? if evb is not recognized by the gui, uninsta ll .net framework 2.0 and reinstall from the installation cd or microsoft?s website. the gui requires .net framework 2.0; however, multiple versions such as 1.1, 2.0, and 3.0 may be installed simultaneously. initialization gui crashes ?? the gui may crash if a previous gui .ini file was not removed properly. close the gui, and delete all .ini files from the gui directory. launch the gui and try again. ?? if the gui continues to crash, cl ose the gui, remove the gui from control panel ? add or remove programs, and then delete the gui directory. launch the gui and try again. receive audio clicking noise ?? disable "update" under the "control" menu (disables continuous gui/si47xx updates). receive excess interference/ poor reception ?? if using a laptop, ensure it is ru nning off the battery and not plugged in to the ac mains. ?? alternatively, disconnect from the host pc and run from battery power. ?? move to a stronger signal environment. receive seek/scan doesn?t find expected channels ?? adjust seek snr and seek rssi thresholds downwards. ?? verify band and channel spacing for the region. receive seek/scan stops on noise ?? adjust seek snr and seek rssi thresholds upwards. ?? if using a laptop, ensure it is ru nning off the battery and not plugged in to the ac mains. fm/wb receive poor sensitivity from fm test port ?? remove ac coupling cap from the headphone input path to eliminate possible sources of interference. si47xx-evb rev. 0.8 111 am receive excess interference/ poor reception 1. check the antenna board connection on j2. 2. make sure the ferrite bar is not loose and does not slide in the coil. 3. if using a laptop, ensure it is running off the battery and not plugged in. 4. alternatively, disconnect from the host pc and run from battery power. 5. move to a stronger signal environment. make sure you are close to a window or outside in the open when evaluating am reception. large metal structures, like buildings, interfere with am reception so it is best to be away from these sources of interference. fm transmit audio distorted/limiter engaging excessively ?? confirm that audio input levels match the line input attenuation and maximum line input levels. ?? disable or scale back the gain of the audio dynamic range control. fm transmit poor transmit audio quality ?? increase the rf level. ?? increase the audio deviation level. ?? change the rf frequency to a channel with less interference. the rps feature can be used to find candidate frequencies. table 28. debugging guidelines for si47xx evb mode symptom solution si47xx-evb 112 rev. 0.8 11. bill of materials table 29.
