We are trying to use the AD1938 coded in bi-directional audio system and the codec is being used in a standalone mode without any external SPI connection. The ADC is placed in master mode (with COUT pulled up) but we would like to use the DAC in slave mode in order to receive the LRCLK from another unit, could you please advise us on how to get just the DAC to receive the LRCLK rather than using the internal master clock generated from the 12.288 oscillator
we want to use the ADC and DAC a-synchronously.
we want to generate the ADC clock from an external source
and generate the DAC clock from the PLL and LRCLK
this is URGENT.
can someone please help
