PCMIN
PCM signal input.
The serial input PCM signal is converted from digital to analog, synchronizing with the synchronous
signal RSYNC and clock signal RCLOCK.
The data rate of PCM signal ranges from 64 kbps to 2048 kbps.
The PCM signal is read at the falling edge of the clock signal and latched into the internal register
when finished to read eight bits data.
The top of the PCM data is specified by RSYNC pulse timing.
RCLOCK
Receive clock pulse input.
The frequency of this clock pulse should be identified with the data rate of PCM input signal at the
PCMIN pin.
This RCLOCK signal can be a continuous clock or a burst clock with nine bits or more.
In the case of a burst clock, input the following timing.

XCLOCK
Transmit clock input.
The PCM output data rate from the PCMOUT pin is set by this clock frequency.
The applicable clock frequencies range from 64 kHz to 2048 kHz.
This XCLOCK signal can be a continuous clock or a burst clock with nine bits or more.
In the case of a burst clock, input the following timing.
