Dear TI-er.
I want bidirectional I2S to PCM converter using to LM49352.
How I set to the register ?

Kiyong SON,
For a bidirectional bridge the sampling rates must be the same.
Also it should be noted that the LM49352 must act as the audio bus Master for one of the audio ports.

Dear TI-er.
Is LM49370 best choice for asymmetric sampling rates ?
Before THKS.
Kiyong SON,
The LM49370 can also not do bidirectional asymmetric sample rates.
from the application report SNAA039A: AN-1591 LM49370 PCM/I2S Bridge
both devices could do unidirectional conversion with different sample rates.

Hi Steve,
I got this link from Kiyong Son.
Previous your comments is helpful to narrow down our problem and to get solution.
But we need further more help to fix it without try-and-error after this time.
So we'd like to exchange lots of information and idea it might be restricted.
Therefore I'd like to open e-mail loop including Kiyoung Son.
Pls mail us as my e-mail address : jonghyun.lee@ericsson.com
Thanks for your support in advance.

Therefore, we'd like to exchange lots of information and idea which might be restricted.
So it will be more suitable by e-mail than open-web page.

JH,
Yes, we can connect via email or you can send me a private message on this forum.
I would like to stress that you carefully read the application note I linked to above. it specifically refers to the LM49370, but is very applicable to the LM49352.

Dear TI-er
I was recommending to double design for bidirectional system.
or
I was recommending to SRC4190 device for its system.
Kinyong SON,
Great, from your early diagrams it did not appear that way, but I understand now.
Best regards,

Kinyong SON,
Using two LM49352s or adding an SRC would allow for bi directional at different sample rates.
