I'm using ADZS-21489-EZLITE board.
For getting a stereo signal from the AD1939 (using the RCA connector provided by the EzLite board),
I want to use the following:
- ABCLK (21489 is master)
- ALRCLK (21489 is master)
In parallel, for getting a multichannel stream and outputting a multichannel stream, I would like to use:
- DBCLK (21489 is slave)
- DLRCLK (21489 is slave)
The idea is to connect another codec on the "expansion II interface"
(after switching OFF SW2.1 -> SW2.6)
Can you please confirm:
1- that this configuration is realistic and feasible?
2- If yes, what could you propose for handling the fact that the TDM & ADSP-21489 doesn't share the same clock?
a. is it needed to use SRC on the ADSP side for the TDM stream?
b. Or can the TDM clock be used as a "master" clock for the ADSP-21489?
3- Do you see some tricky things to be handled here and any related recommendations?
Thanks in advance for the support,
