Other Parts Discussed in Thread: PCM3168
We are using the codec in a slave mode TDM8 512xFs, 48KHz, master clock is 24.576MHz.
LRCLK and BCLK are provided by a DSP. Master clocks to the codec and DSP are coming from the same source.
Both codec and DSP are configured for I2S TDM8 audio format.
The TDM8 output of a codec doesn't lock to the start of the LRCLK frame. Instead it locks at occasional place.
If I restart DSP, TDM8 out locks at a different place, but still not to the start of a LRCLK frame.
What could be a reason for it?
Another question. In one of the codecs (we use four) we need to use only AD, but no DA.
Nevertheless there is no TDM8 from output from this codec if DA audio clocks are not connected.
Is that how it's supposed to be?
Thank you,
Gennady
