Other Parts Discussed in Thread: PCM3168

New to PCM3168, just want to know if it is ued as I2S TDM mode, we only need LRCKAD and BCKAD for both DIN1 and DOUT1? or (LRCKAD, BCKAD for DIN1; LRCKDA, BCKDA for DOUT1)?

David,

Per page 23 of the d/s, it depends on whether single/dual/quad rate is used.

Thanks for reply. It seems PCM3168 is not using PCM highway interface, and we must use AD clock(s) for DIN, and DA clock(s) for DOUT?

And another question, for unused VOUT pins, and we need some kind of terminating methods?

Thanks.
