Hi
MA12070 eval audio boards not being syncronized.
My slave unit does not respond as it should. Only noise. Not sure I wired it correctly but I would like some comment on how to do this right.

Hello User18897.
Your schematic looks correct. The master MA12070 device should be able to act as master clock for the slave MA12070 this way. Please make shure that the ground/references for the two boards are solid connected together, as any ground noise (caused by different current draws) can couple into the clock i/o line. A small series resistor of 33ohm could be placed in series with the clock i/o line to remove reflections in this transmission line.
Please ask if any more questions.
BR, Rasmus Meyer.
