Forum Post: RE: C6746 McASP to support 512 TDM channels via McASP

Hi Feroz,

Thanks for your post.

I don't think, we have benchmarks on this usecase and even, it may not be possible to use all 16 serializers with all 32- time slots. I mean, receive section usually supports TDM streams from 2 to 32 time slots, but in a special case,it is possible to use TDM streams of 384 slots while interfacing to external digital interface receiver (DIR) transmitting DIR frames to McASP through I2S.

Please refer Section 22.1.3 in the C6746 TRM as below:

We do have benchmark data only for McASP max. throughput in the below wiki:
