OPERATION OVERVIEW
■
System Clock
The input port works in slave mode only. The output port works in slave and master mode. An internal system clock is
created by the internal PLL using ILRCK. The MCLK is not needed when the output port is in slave mode, and the
MCLK pin should be connected to DVSS. The CMODE2-0 pins must be controlled when PDN pin =“L”.

Audio Interface Format
The IDIF2-0 pins select the data mode for the input port. The ODIF1-0 pins select the data mode for the output port. In
all modes the audio data is MSB-first, 2’s compliment format. The SDTO is clocked out on the falling edge of OBICK.
Select these modes when PDN pin=“L”. In BYPASS mode, both IBICK and OBICK are fixed to 64fs.
