System Clock & Audio Interface Format for Output PORT
The output port works in slave mode. The clocks supply OLRCK and OBICK externally. The ODIF1-0 pins and OBIT1-0
pins select the audio interface format for the output port. The audio data is MSB first, 2’s complement format. The SDTO
is clocked out on the falling edge of OBICK. Select the audio interface format when PDN pin = “L”. The audio interface
format of SDTO1, SDTO2 and SDTO3 becomes the same setting. The maximum input frequency of OBICK is 64fso.
