Pulse Timing
The first PCM data is output from TXD at the positive edge of -FSYNC. The second data and the followings are output
at the positive edge of BCLK. After all data of 8 bit are output, the last data is kept until the positive edge of next -
FSYNC. The positive edge of BCLK should be within
±
100ns from the positive edge of -FSYNC.
The PCM data input from RXD is sampled at the negative edge of BCLK inside LSI. The sampling of the first data is
performed between the positive edge of -FSYNC and the first negative edge of BCLK. After completing the sampling of
all data of 8 bit, this sampling pauses until the next positive edge of -FSYNC.
6) PCM interface (between IC1 and IC2)
PCM interface consists of following 4 terminals.
