PCM2900C: Absolute phase between USB data to ADC in and DAC out

Part Number: PCM2900C

Hello,

Our customer give us question, what is absolute phase characteristics of PCM2900C when connect PC via USB.

When look at PCM2900CEVM, there is Inverted ant-arias filter to ADC and Inverted Post LPF from DAC.

Does PCM2900CEVM Analog in/out keep absolute phase for USB audio data? That is meaning PCM2900C ADC and DAC in/out pin itself is out of phase between USB.

We cannot find absolute phase specification on the datasheet, could you please clarify it.

 

Regards,

Mochizuki

    Hi, Mochizuki-san,

    This was not characterized for this device so the spec is not available. We will check if we have further details about this and will contact you back once we get any feedback.
