Pin Description
MCLK Frequency (Input) - Sets the required frequency range of the input Master Clock. See sec-
tion
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.
Serial Clock (Input) - Serial clock for the serial audio interface. Input frequency must be 256xFs.
Serial Audio Data Output (Output) - TDM output for two’s complement serial audio data.
DAC Serial Audio Data Input (Input) - 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.
Auxiliary Serial Clock (Output) - Serial clock for the Auxiliary serial audio interface.
Auxiliary Serial Input (Input) - The 42432 provides an additional serial input for two’s comple-
ment serial audio data.
