Serial Control Port Clock (Input) - Serial clock for the control port interface.
Serial Control Data I/O (Input/Output) - Input/Output for I²C data. Output for SPI data.
Address Bit [0]/ Chip Select (Input) - Chip address bit in I²C Mode. Control signal used to select
the chip in SPI Mode.
Address Bit [1]/ SPI Data Input (Input) - Chip address bit in I²C Mode. Input for SPI data.
Reset (Input) - The device enters a low-power mode and all internal registers are reset to their
default settings when low.
Control Port Power (Input) - Determines the required signal level for the control port interface.
See
Frame Sync (Input) - Signals the start of a new TDM frame in the TDM digital interface format.
Digital Power (Input) - Positive power supply for the digital section.
Serial Port Interface Power (Input) - Determines the required signal level for the serial port inter-
faces. See
Serial Clock (Input) - Serial clock for the serial audio interface. Input frequency must be 256 x Fs.
Master Clock (Input) - Clock source for the delta-sigma modulators and digital filters.
Serial Audio Data Output (Output) - TDM output for two’s complement serial audio data.
DAC Serial Audio Data Input (Input) - TDM Input for two’s complement serial audio data.
Auxiliary Left/Right Clock (Output) - Determines which channel, Left or Right, is currently active
on the Auxiliary serial audio data line.
