TDA4VM-Q1: Audio with TDM Interface

The interface is fully programmable.  All McASP data pins can be used for either input or output, and there is no specific order (any data bit can be used for any function).  Most designs use a reference clock (audio_ext_refclk) sourced from TDA4VM-Q1, along with MCASP bit clock (ACLKX), word clock (AFSX), and two data bits (AXR) - one for transmit one for receive

The Jacinto7 Common Processor board includes a audio codec as an example.

Hi Robert,

Thank you for the comment.

Let me summarize the net name as below(Yellow marks mean customer can choose accordingly based on their configuration which pins are available):

Bit Clock -> MCASPx_ACLKX

Frame Clock -> MCASPx_AFSX

Data (Input + Output)-> MCASPx_AXRx

Master Clock -> AUDIO_EXT_REFCLKx

Kindly correct me if I was wrong.

Correct - the McASP signals needs to be from single McASP interface (all from McASP0 for example).  Any AUDIO_EXT_REFCLK can be used.  Data Input is typically one McASPx_AXRx and data output is typically a different data bit McASPx_AXRy
