AD1938-ADSP 21364 interface..... - cee4max - Jan 3 9:20:19 2008



Hello,

I am using AD 1938 for getting the audio data to be processed by ADSP
21364,
is it possible to configure AD1938 at 44.1KHz sampling rate and still
communicate with the ADSP 21364.

With Best Regards,
Saju.

Yes,

We interface as many as 4 AD1938s with our dspstak  c192k48 cards. If 
you have having trouble, it may be due to the DMA errata  of the 21364. 
We recommend  ADSP-21369  or ADSP-21371  to our customers. You should 
also have small resistors (22-33 ohm) in series with each line on the 
driving side of the connection.
