AVB with TDM slave X200 ? using lib_tsn

AVB TDM slave exteranl clock source.png

I would like to connect SD from my DSP for AVB 8 channel IO and make an AVB endpoint.
The DSP is MASTER and generates MCLK LRCLK BCLK

I am using custom hardware but it shares the same design as evaluation boards regarding the PHY.
the audio is supplied over TDM 8 from DSP rather the directly from ADC and DAC.

I took a look at TSN 7.0.2 and AN00203 ( gigabit ethernet AVB endpoint example using TDM master.

I am wondering if its possible to make the TDM interface as SLAVE to my other MCLK generated from a DSP.

would the media clock server need to share the same clock source for the listener to stay in sync or can it sync
to the audio interface regardless ?

if its a requirement that AVB drives the MCLK of the audio hardware to stay in sync with other endpoints on the network
then I suppose the answer is that XMOS must be MASTER ( be able to condition the speed of the MCLK and the hardware ! )

if this is the case the I will need to use a CS2100-CP ( or similar ) to drive the DSP clock source while the device is in AVB mode.

I think I just answered my own question here , but any additional thoughts would be appreciated !

Hello,
I'm new to XMOS device but I have experience with audio Codec.
What devboard would you recommand to start developping AVB and connecting a TDM device?
I found a documentation about the XK-AVB-LC-SYS devboard but that board seems to be obsolete.
Thank you very much
Have a nice day
