Part Number: PCM5142
Other Parts Discussed in Thread: CC2564

Hi 

I'm using CC2564 - PCM5142.

Actually, I want to output L,R same phase.

How can I do this? Is there a function for this in PCM5142 ?

some tips?

Thank you

    Hi Minkyo,

    The two outputs should already be in the same phase. If you think that one channel is a sample ahead (or behind) the other channel, then I suspect that the LRCK is inverted or there is a phase issue in the I2S source.

    Or do you mean that you want the two channels to be identical, like they are both playing the left or right channel? If that is the case, you can do that by writing to DAC Datapath Registers (Page 0, Register 42).

    Thanks,
    Paul
