When applied, the system clock must be locked in frequency to the corresponding digital interface clocks. The voice ADC part can either receive or generate the WSV signal as shown in Table 3. The UDA1338H operates in slave mode only; this means that in all applications the system must provide either the system clock (the bit clock for the voice ADC) or the word clock. The audio ADC part, the voice ADC part and the DAC part can operate at different sampling frequencies (DAC-WS and ADC-WS modes) as well as a common frequency (SYSCLK, WSDA and DSD modes). The voice ADC part supports a sampling frequency up to 50 kHz and the audio ADC supports a sampling frequency up to 100 kHz. The DAC sampling frequency range is extended up to 200 kHz with the range above 100 kHz being supported through 192 kHz sampling mode, which halves the oversampling ratio of SYSCLK and internal clocks.

Using the PGA feature, it is possible to accept an input signal of 900 mV (RMS) or 1.8 V (RMS) if an external resistor of 10 k is used in series. The schematic of audio ADC front-end is shown in Fig.3. The voice ADC decimation filter is realized with the combination of a Finite Impulse Response (FIR) filter and Infinite Impulse Response (IIR) filter for shorter group delay. The filter characteristics are shown in Table 5. During the power-on sequence, the output of the ADC is hard muted for a certain period. This hard-mute time can be chosen between 1024 and 2048 samples.

The digital interpolation filter interpolates from 1fs to 128fs (or to 64fs in the 192 kHz sampling mode) by cascading FIR filters, and has two sets of filter coefficients for sharp and slow roll-off as given in Tables 6 and 7.

Together with the digital variable gain amplification stage, the voice ADC provides optimal processing and reproduction of the microphone signal. The supported sampling frequency range is from 7 to 50 kHz. Power-down of the LNA and the ADC can be controlled separately. 8.4 Decimation filter of audio ADC 4 ITEM Pass-band ripple Stop band Dynamic range Table 7 Interpolation filter characteristics (slow roll-off) CONDITION 0 to 0.22fs 0.45fs >0.78fs 0 to 0.22fs VALUE (dB) 0.002 -3.1 -94 >135 ITEM Pass-band ripple Pass-band droop Stop band Dynamic range 8.7 The decimation from 64fs is performed in two stages. sin x The first stage realizes ---------- x - characteristics with a decimation factor of 8. The second stage consists of three half-band filters, each decimating by a factor of 2. The filter characteristics are shown in Table 4. Table 4 Decimation filter characteristics (audio ADC) CONDITION 0 to 0.45fs 0.45fs >0.55fs 0 to 0.45fs VALUE (dB) 0.01 -0.2 -70 >135 9 Noise shaper of DAC ITEM Pass-band ripple Pass-band droop Stop band Dynamic range 2002 Nov 21 The 3rd-order noise shaper operates at either 128fs or 64fs (in the 192 kHz sampling mode), and converts the 24-bit input signal into a 5-bit signal stream. The noise shaper shifts in-band quantization noise to frequencies well above the audio band. This noise shaping technique enables high signal-to-noise ratios to be achieved. Philips Semiconductors Preliminary specification Multichannel audio coder-decoder 8.8 Digital mixer UDA1338H The UDA1338H has 6 digital mixers inside the interpolator (see Fig.4). The ADC signals can be mixed with the I2S-bus input signals. The mixing of the ADC signals can be selected by the bits MIX[1:0].

To minimize data dependent modulation effects, a Dynamic Element Matching (DEM) algorithm scrambler circuit and DC current compensation circuit are implemented with the SDAC. 8.10 Power-on reset The reset time (see Fig.6) is determined by an external capacitor which is connected between pin Vref and ground. The reset time should be at least 250 s for Vref < 1.25 V. When VDDA(AD) is switched off, the device will be reset again for Vref < 0.75 V. During the reset time, the system clock should be running. The UDA1338H has an internal power-on reset circuit which initializes the device (see Fig.5). All the digital sound processing features and the system controlling features are set to their default values in the L3-bus and the I2C-bus modes. 2002 Nov 21 10 Philips Semiconductors Preliminary specification Multichannel audio coder-decoder 8.11 Audio digital interface UDA1338H handbook, halfpage VDDA(AD) 9 k Vref C1 > 10 F 9 k MGU585 The following audio formats can be selected via the microcontroller interface: * I2S-bus format with data word length of up to 24 bits RESET CIRCUIT * MSB-justified format with data word length of up to 24 bits * LSB-justified format with data word length of 16, 20 or 24 bits * Multichannel formats with data word length of 20 or 24 bits.

The address mode is characterized by signal L3MODE = LOW and a burst of 8 pulses for signal L3CLOCK, accompanied by 8 bits (see Fig.11). The data transfer mode is characterized by signal L3MODE = HIGH and is used to transfer one or more bytes representing a register address, instruction or data. Basically, two types of data transfers can be defined: * Write action: data transfer to the device * Read action: data transfer from the device. 9.2 Device addressing The microcontroller interface mode can be selected as shown in Table 8: * L3-bus mode when pin I2C_L3 = LOW * I2C-bus mode when pin I2C_L3 = HIGH.

The detailed description of the device operation in the L3-bus mode and I2C-bus mode is given in Chapters 9 and 10, respectively. 9 9.1 L3-BUS INTERFACE General Register addressing The UDA1338H has an L3-bus microcontroller interface and all the digital sound processing features and various system settings can be controlled by a microcontroller. The exchange of data and control information between the microcontroller and the UDA1338H is LSB first and is accomplished through a serial hardware L3-bus interface comprising the following pins: * MCCLK: clock line with signal L3CLOCK * MCDATA: data line with signal L3DATA * MCMODE: mode line with signal L3MODE. The L3-bus format has two modes of operation: * Address mode * Data transfer mode. After sending the device address (including DOM bits), indicating whether the information is to be read or written, one data byte is sent using bit 0 to indicate whether the information will be read or written and bits 1 to 7 for the destination register address. Basically, there are 3 methods for register addressing: 1. Addressing for write data: bit 0 is logic 0 indicating a write action to the destination register, followed by bits 1 to 7 indicating the register address (see Fig.11) 2.

Philips Semiconductors Preliminary specification Multichannel audio coder-decoder 9.4 Data write mode UDA1338H For reading data from a device, the following 6 bytes are involved (see Table 12): 1. Byte 1 with the device address, including `01' for signalling the write action to the device. 2. Byte 2 is sent with the register address from which data needs to be read. This byte starts with a `1', which indicates that there will be a read action from the register, followed by 7 bits for the destination address in binary format, with bit A6 being the MSB and bit A0 being the LSB. 3. Byte 3 with the device address, including `11' is sent to the device. The `11' indicates that the device must write data to the microcontroller. 4. Byte 4 sent by the device to the bus, with the (requested) register address and a flag bit indicating whether the requested register was valid (bit is logic 0) or invalid (bit is logic 1). 5. Byte 5 sent by the device to the bus, with the data information in binary format, with bit D15 being the MSB. 6. Byte 6 sent by the device to the bus, with the data information in binary format, with bit D0 being the LSB. The data write mode is explained in the signal diagram of Fig.11. For writing data to a device, 4 bytes must be sent (see Table 11): 1. Byte 1 starting with `01' for signalling the write action to the device, followed by the device address `01 0100'. 2. Byte 2 starting with a `0' for signalling the write action, followed by 7 bits indicating the destination address in binary format with bit A6 being the MSB and bit A0 being the LSB. 3. Byte 3 with bit D15 being the MSB. 4. Byte 4 with bit D0 being the LSB. It should be noted that each time a new destination register address needs to be written, the device address must be sent again. 9.5 Data read mode To read data from the device, a prepare read must first be done and then data read. The data read mode is explained in the signal diagram of Fig.12.

All the features are accessible with the I2C-bus interface protocol. In the I2C-bus mode, the DAC mute function is accessible via pin MCMODE with signal QMUTE. The exchange of data and control information between the microcontroller and the UDA1338H is accomplished through a serial hardware interface comprising the following pins as shown in Table 8: * MCCLK: clock line with signal SCL * MCDATA: data line with signal SDA. 10.2 Characteristics of the I2C-bus One data bit is transferred during each clock pulse (see Fig.13). The data on the SDA line must remain stable during the HIGH period of the clock pulse as changes in the data line at this time will be interpreted as control signals. The maximum clock frequency is 400 kHz. To be able to run on this high frequency, all the inputs and outputs connected to this bus must be designed for this high-speed I2C-bus according to the Philips specification. 10.4 Byte transfer Each byte (8 bits) is transferred with the MSB first (see Table 13). Table 13 Byte transfer MSB 7 10.5 6 5 BIT NUMBER 4 3 2 1 LSB 0 The bus is for 2-way, 2-line communication between different ICs or modules. The two lines are a serial data line (SDA) and a serial clock line (SCL). Both lines must be connected to the supply voltage VDD via a pull-up resistor when connected to the output stages of a microcontroller. For a 400 kHz IC, the recommendation for this type of bus from Philips Semiconductors must be followed (e.g. up to loads of 200 pF on the bus a pull-up resistor can be used, between 200 and 400 pF a current source or switched resistor must be used). Data transfer can only be initiated when the bus is not busy. Data transfer A device generating a message is a transmitter; a device receiving a message is the receiver. The device that controls the message is the master and the devices which are controlled by the master are the slaves. handbook, full pagewidth SDA SCL data line stable; data valid change of data allowed MBC621 Fig.13 Bit transfer on the I2C-bus. 2002 Nov 21 18 Philips Semiconductors Preliminary specification Multichannel audio coder-decoder 10.6 Start and stop conditions UDA1338H A slave receiver which is addressed, must generate an acknowledge after the reception of each byte. Also a master must generate an acknowledge after the reception of each byte that has been clocked out of the slave transmitter. The device that acknowledges has to pull down the SDA line during the acknowledge clock pulse, so the SDA line is stable LOW during the HIGH period of the acknowledge related clock pulse. Set-up and hold times must be taken into account. A master receiver must signal an end of data to the transmitter by not generating an acknowledge on the last byte that has been clocked out of the slave. In this event, the transmitter must leave the data line HIGH to enable the master to generate a stop condition. Both data and clock line will remain HIGH when the bus is not busy. A HIGH-to-LOW transition of the data line, while the clock is HIGH, is defined as a start condition (S); see Fig.14. A LOW-to-HIGH transition of the data line while the clock is HIGH is defined as a stop condition (P). 10.7 Acknowledgment The number of data bits transferred between the start and stop conditions from the transmitter to receiver is not limited. Each byte of eight bits is followed by one acknowledge bit (see Fig.15). At the acknowledge bit the data line is released by the master and the master generates an extra acknowledge related clock pulse. handbook, full pagewidth SDA SDA SCL S START condition P STOP condition SCL MBC622 Fig.14 START and STOP conditions on the I2C-bus. handbook, full pagewidth DATA OUTPUT BY TRANSMITTER not acknowledge DATA OUTPUT BY RECEIVER acknowledge SCL FROM MASTER S START condition clock pulse for acknowledgement MBC602 1 2 8 9 Fig.15 Acknowledge on the I2C-bus. 2002 Nov 21 19 Philips Semiconductors Preliminary specification Multichannel audio coder-decoder 10.8 Device address I2C-bus, 10.9 Register address UDA1338H the device Before any data is transmitted on the which should respond is addressed first. The addressing is always done with byte 1 transmitted after the start procedure. The UDA1338H acts as a slave receiver or a slave transmitter. Therefore, the clock signal SCL is only an input signal. The data signal SDA is a bidirectional line. The UDA1338H device address is shown in Table 14.

The write cycle is used to write groups of two bytes to the internal registers for the settings. It is also possible to read the registers for the device status information. 2002 Nov 21 20 This text is here in white to force landscape pages to be rotated correctly when browsing through the pdf in the Acrobat reader.This text is here in _white to force landscape pages to be rotated correctly when browsing through the pdf in the Acrobat reader.This text is here inThis text is here in white to force landscape pages to be rotated correctly when browsing through the pdf in the Acrobat reader. white to force landscape pages to be ... 10.11 Write cycle 2002 Nov 21 2002 Nov 21 21 21 S Note 1. Auto increment of register address. Philips Semiconductors Multichannel audio coder-decoder Multichannel audio coder-decoder The I2C-bus configuration for a write cycle is shown in Table 15. The write cycle is used to write the data to the internal registers. The device and register addresses are one byte each, the setting data is always a pair of two bytes. The format of the write cycle is as follows: 1. The microcontroller starts with a start condition (S). 2. The first byte (8 bits) contains the device address `0011 000' and a logic 0 (write) for the R/W bit. 3. This is followed by an acknowledge (A) from the UDA1338H. 4. After this the microcontroller writes the 8-bit register address (ADDR) where the writing of the register content of the UDA1338H must start. 5. The UDA1338H acknowledges this register address (A). 6. The microcontroller sends 2 bytes data with the Most Significant (MS) byte first and then the Least Significant (LS) byte. After each byte an acknowledge is followed from the UDA1338H. 7. If repeated groups of 2 bytes data are transmitted, then the register address is auto incremented. After each byte an acknowledge is followed from the UDA1338H. 8. Finally, the UDA1338H frees the I2C-bus and the microcontroller can generate a stop condition (P).

The first byte (8 bits) contains the device address `0011 000' and a logic 0 (write) for the R/W bit. 3. This is followed by an acknowledge (A) from the UDA1338H. 4. After this the microcontroller writes the 8-bit register address (ADDR) where the reading of the register content of the UDA1338H must start. 5. The UDA1338H acknowledges this register address. 6. Then the microcontroller generates a repeated start (Sr). 7. Then the microcontroller generates the device address `0011 000' again, but this time followed by a logic 1 (read) of the R/W bit. An acknowledge is followed from the UDA1338H. 8. The UDA1338H sends 2 bytes data with the Most Significant (MS) byte first and then the Least Significant (LS) byte. After each byte an acknowledge is followed from the microcontroller (master). 9. If repeated groups of 2 bytes are transmitted, then the register address is auto incremented. After each byte an acknowledge is followed from the microcontroller. 10. The microcontroller stops this cycle by generating a negative acknowledge (NA). 11.

The footprint must incorporate solder thieves at the downstream end. * For packages with leads on four sides, the footprint must be placed at a 45 angle to the transport direction of the printed-circuit board. The footprint must incorporate solder thieves downstream and at the side corners. During placement and before soldering, the package must be fixed with a droplet of adhesive. The adhesive can be applied by screen printing, pin transfer or syringe dispensing. The package can be soldered after the adhesive is cured. Typical dwell time is 4 seconds at 250 C. A mildly-activated flux will eliminate the need for removal of corrosive residues in most applications. 20.4 Manual soldering This text gives a very brief insight to a complex technology. A more in-depth account of soldering ICs can be found in our "Data Handbook IC26; Integrated Circuit Packages" (document order number 9398 652 90011). There is no soldering method that is ideal for all surface mount IC packages. Wave soldering can still be used for certain surface mount ICs, but it is not suitable for fine pitch SMDs. In these situations reflow soldering is recommended. 20.2 Reflow soldering Reflow soldering requires solder paste (a suspension of fine solder particles, flux and binding agent) to be applied to the printed-circuit board by screen printing, stencilling or pressure-syringe dispensing before package placement. Several methods exist for reflowing; for example, convection or convection/infrared heating in a conveyor type oven. Throughput times (preheating, soldering and cooling) vary between 100 and 200 seconds depending on heating method. Typical reflow peak temperatures range from 215 to 250 C. The top-surface temperature of the packages should preferable be kept below 220 C for thick/large packages, and below 235 C for small/thin packages. 20.3 Wave soldering Conventional single wave soldering is not recommended for surface mount devices (SMDs) or printed-circuit boards with a high component density, as solder bridging and non-wetting can present major problems. To overcome these problems the double-wave soldering method was specifically developed. Fix the component by first soldering two diagonally-opposite end leads. Use a low voltage (24 V or less) soldering iron applied to the flat part of the lead. Contact time must be limited to 10 seconds at up to 300 C. When using a dedicated tool, all other leads can be soldered in one operation within 2 to 5 seconds between 270 and 320 C. 2002 Nov 21 49 Philips Semiconductors Preliminary specification Multichannel audio coder-decoder 20.5 Suitability of surface mount IC packages for wave and reflow soldering methods PACKAGE(1) BGA, LBGA, LFBGA, SQFP, TFBGA, VFBGA HBCC, HBGA, HLQFP, HSQFP, HSOP, HTQFP, HTSSOP, HVQFN, HVSON, SMS PLCC(4), SO, SOJ LQFP, QFP, TQFP SSOP, TSSOP, VSO Notes not suitable not suitable(3) UDA1338H SOLDERING METHOD WAVE REFLOW(2) suitable suitable suitable suitable suitable suitable not not recommended(4)(5) recommended(6) 1. For more detailed information on the BGA packages refer to the "(LF)BGA Application Note" (AN01026); order a copy from your Philips Semiconductors sales office. 2. All surface mount (SMD) packages are moisture sensitive. Depending upon the moisture content, the maximum temperature (with respect to time) and body size of the package, there is a risk that internal or external package cracks may occur due to vaporization of the moisture in them (the so called popcorn effect). For details, refer to the Drypack information in the "Data Handbook IC26; Integrated Circuit Packages; Section: Packing Methods". 3. These packages are not suitable for wave soldering. On versions with the heatsink on the bottom side, the solder cannot penetrate between the printed-circuit board and the heatsink. On versions with the heatsink on the top side, the solder might be deposited on the heatsink surface. 4. If wave soldering is considered, then the package must be placed at a 45 angle to the solder wave direction. The package footprint must incorporate solder thieves downstream and at the side corners. 5. Wave soldering is suitable for LQFP, TQFP and QFP packages with a pitch (e) larger than 0.8 mm; it is definitely not suitable for packages with a pitch (e) equal to or smaller than 0.65 mm. 6. Wave soldering is suitable for SSOP and TSSOP packages with a pitch (e) equal to or larger than 0.65 mm; it is definitely not suitable for packages with a pitch (e) equal to or smaller than 0.5 mm. 2002 Nov 21 50 Philips Semiconductors Preliminary specification Multichannel audio coder-decoder 21 DATA SHEET STATUS LEVEL I DATA SHEET STATUS(1) Objective data PRODUCT STATUS(2)(3) Development DEFINITION UDA1338H This data sheet contains data from the objective specification for product development.
