SYNC
8 kHz synchronous signal input for transmit and receive PCM data.
Synchronize this signal with BCLK signal. This signal is used to indicate the MSB of the PCM data stream.
PCMOUT
Transmit PCM data output. The PCM output signal is output from MSB, synchronously with the rising edges of
BCLK and SYNC. Refer to Figure 2. This is a logic output pin so that external pull-up is not required. This pin
outputs logic "L" except during effective PCM data bits, and outputs logic "H" during power-down.
PCMIN
Receive PCM data input.
The PCM input signal is shifted in on the falling edge of BCLK and is input from MSB.
Refer to Figure 2.
