- Frame sync signal
FS
8kHz reference signal. This signal indicated the timing and the frame position of 8kHz PCM interface.
All the internal clock of the LSI is generated based on this FS signal.
-Bit clock
BCLK
BCLK defines the PCM data rate. BCLK rate is 256kHz or 512kHz. This clock must be synchronized
with FS.
