The nominal rate might be the same but if they're in different clock domains then the actual rates might be different (hence the desire for an ASRC I guess). I can see the system wanting to choose one clock or the other on the basis of some system specific property (quality of the clock sources, tolerances of the devices involved or something) though it's a rather fun edge case configuration :/ .
Thanks for the input. Fox i.MX6, I don't feel it would be that drastically different though. And both SSI1 and SSI2 can simply select the same root clock source to avoid that happen.
If you've got two radios that both need to sync to some radio derived frequency it gets a bit more entertaining.
I'm simply curious what could be a problem. Do you mind educating me a bit? And ASRC here isn't a radio but a sample rate converter working as a BE in DPCM setup, using radio-capture for example...
