Hi team,

What's the data delay time from ADC input to USB output in PCM2900C? Thank you.

Hi, Lilian,

The typical delay time for the ADC of the PCM2900C is specified in the datasheet, and is 17/Fs, being Fs the sampling rate of the Codec. As example, for a 48KHz sampling rate, the expected delay is 0.354ms.

Best Regards,

Hi Diego,

This delay time is only for ADC digital filter response time? The FIFO and USB block are not included?

Thank you.
