6 / 64 page 6 DS646PP2 1 PIN DESCRIPTION - SOFTWARE MODE Pin Name # Pin Description SCL/CCLK 1 Serial Control Port Clock (Input) - Serial clock for the control port interface. SDA/CDOUT 2 Serial Control Data I/O (Input/Output) - Input/Output for I2C data. Output for SPI data. AD0/CS 3 Address Bit [0]/ Chip Select (Input) - Chip address bit in I2C Mode. Control signal used to select the chip in SPI mode. AD1/CDIN 4 Address Bit [1]/ SPI Data Input (Input) - Chip address bit in I2C Mode. Input for SPI data. RST 5 Reset (Input) - The device enters a low power mode and all internal registers are reset to their default settings when low. VLC 6 Control Port Power (Input) - Determines the required signal level for the control port interface. See “Digital I/O Pin Characteristics” on page 7. FS 7 Frame Sync (Input) - Signals the start of a new TDM frame in the TDM digital interface format. VD 8 Digital Power (Input) - Positive power supply for the digital section. DGND 9,18 Digital Ground (Input) - VLS 10 Serial Port Interface Power (Input) - Determines the required signal level for the serial port inter- faces. See “Digital I/O Pin Characteristics” on page 7. SCLK 11 Serial Clock (Input) - Serial clock for the serial audio interface. Input frequency must be 256xFs. MCLK 12 Master Clock (Input) - Clock source for the delta-sigma modulators and digital filters. ADC_SDOUT 13 Serial Audio Data Output (Output) - TDM output for two’s complement serial audio data. DAC_SDIN 14 DAC Serial Audio Data Input (Input) - TDM Input for two’s complement serial audio data. AUX_LRCK 15 Auxiliary Left/Right Clock (Output) - Determines which channel, Left or Right, is currently active on the Auxiliary serial audio data line.
