SI535X-24QSOP-EVB 2 preliminary rev. 0.2 1. functional block diagram figure 1 highlights the main features of the evb. the on board mcu is responsible for programming the si535x timing ic, measuring the device's current consumption reported in clockbuilder? desktop, managing power, and controlling status leds. vdd and vddo jumpers allow the option to choose between 2.5 v and 3.3 v or to power the device with external supplies (s ee ?2. jumpers? for details). i 2 c jumpers allow the si535x to be disconnected from the i 2 c bus to allow external control from another i 2 c master. the device can run in stand-alone asynchronous mode using the onboard 27 mhz xtal (y1), or it can be synchronized to an external clock usin g the clkin sma connector or tp39/tp40. figure 1. evb features
SI535X-24QSOP-EVB preliminary rev. 0.2 3 2. jumpers the following jumpers are available on the evaluation board: ? vdd? connects the si5350/51 pin to the vdd voltage regulator (normally installed). ? vdd volt_sel ?allows user to select a vdd voltag e of 2.5 v or 3.3 v (default 3.3 v). ? vddoa ?connects the si5350/51 pin to the vddoa voltage regulator (normally installed). ? vddoa volt_sel ?allows user to select a vddoa volta ge of 2.5 v or 3.3 v (default 3.3 v). ? vddob ?connects the si5350/51 pin to the vddob voltage regulator (normally installed). ? vddob volt_sel ?allows user to select a vddob volta ge of 2.5 v or 3.3 v (default 3.3 v). ? vddoc ?connects the si5350/51 pin to the vddoc voltage regulator (normally installed). ? vddoc volt_sel ?allows user to select a vddoc volt age of 2.5 v or 3.3 v (default 3.3 v). ? vddod ?connects the si5350/51 pin to the vddod voltage regulator (normally installed). ? vddod volt_sel ?allows user to select a vddod volt age of 2.5 v or 3.3 v (default 3.3 v). ? scl ?connects the si5350/51 scl pin to the i 2 c bus from the mcu. removing the jumper breaks the connection to the mcu and allows the user to feed in an external i 2 c signal to the device. ? sda ?connects the si5350/51 sda pin to the i 2 c bus from the mcu. removing the jumper breaks the connection to the mcu and allows the user to feed in an external i 2 c signal to the device. ? exp power ?allows user to select between 5 v usb supply an d 5 v external supply on j17. see figure 1 for jumper locations. 3. status leds there are three status leds on the evaluation board: ? rdy (green)?indicates that the evb is operating normally. this led should always be on. ? busy (green)?indicates that the on-board mcu is co mmunicating with the device and/or the usb host. ? intr (red)?indicates device or evb fault condit ion (also on when dut ha sn't been pr ogrammed). 4. clock inputs the evb can operate in asynchronous mode using the onboard 27 mhz crysta l, in synchronous mode using an external cmos clock source, or in both modes if both plls in the device are utilized. an sma connector is provided to interface an external clock source to clkin. additionally, clkin can be applied using the test hooks tp39/tp49.
SI535X-24QSOP-EVB 4 preliminary rev. 0.2 5. clock outputs outputs must be measured with a high-impedance scope pr obe. a ground test point is provided 0.3" away from each clock output for ideal measurement. most scope pr obes have a ground clip attached to the probe with 3?6" length of cable. use of these ground clips is not recommended since t he ground reference is electrically far from the probe tip, especially for frequencies greater than a few mhz. figure 2 shows the ideal measurement practice. note that the probe ground closest to the probe tip is used as the reference. clock voltage levels can be 2.5 or 3.3 v depend ing on the vddox volt_ sel jumper selection. figure 2. measuring output
