AIC3254 data formatting

Natan Keddem

Is the AIC3254 (or any other MiniDSP based codec) able to communcate its audio data in an 8-bit PCM u-law or a-law format? If not is there any solution to compand the data coming out of the CODEC into the correct format?

I forgot to mention that I would also like to communicate at 8kHz if at all possible. I noticed that the echo cancelation module runs at 8kHz aswell does that mean. My CODEC must be set to an 8kHz sample rate?

Hi nkeddem,

Yes. The AIC3254's PurePath Studio has an A-law and u-law component.

The AIC3254 can do 8kHz. In order to use USB audio at 8kHz sampling, the firmware must be reprogrammed using the AIC3254 CS. Look for the Tools>EEPROM Programmer panel.
