AM5728: AM5728 - I2S, I8S, I16S

JAMIE BROCK

Part Number: AM5728

Hello

I'm new to Sitara, I will be using the AM5728 as my design will be prototyped on beaglebone x15.

I need to output many channels 16/32/64 of digital audio (96KHz, 24bit) from the AM5728 using a 8 channel I2s interface.

Can you please advise if this is possible and the correct approach to use for implementing 4 bidirectional I2S channels (I guess its I8S) in the AM5728?

Should I be using McBSPS?

Your help would be much appreciated

Best regards

Jamie

Hi,

AM572x devices do not have McBSP peripherals. The correct peripheral for your purpose is the McASP, which is described in details in section 26.4 of the AM572x TRM Rev. K. Four bidirectional I2S channels will require 8 serializers. McASP1 and 2 each have 16 serializers, while McASP3 to 8 have 4 each.
