PCM1804: How long is the specific time-delay of input and output ?

Charles Fei

Part Number: PCM1804

As title,I would like to learn about the time delay between input and output. There's no related introduction in PCM1804's Data Sheet.

Hi,

We have received your post and the investigation will take some time. Thank you for your patience.

The group delay of digital filters are the dominant delay elements in these devices and you should find them in the datasheets of audio data converters . It is changes with the sampling frequency of the operation. It is a fixed number times the sampling period (1/fs). For example you should see something like 27/fs or 27*Ts .

Hello，Taylor！Thank you for your replying. The situation is that we have closed our filters and what we want to learn is the time-delay which is from the input of anolog to output of digital. We also have contacted with TI costmer center, but the technogical support told us there was nothing about time-delay in the datasheets.
