We have a problem with some jitter on CLKOUT pin as well as the BCLK pins on our ADAU1467. We supply our MCLK by a 24.576MHz oscillator. Please see the measurement of the 24.576MHz below:
As you can see the clock signal is very stable and no jitter is visable.
But when I hook up to the CLKOUT and BCLK pin, I can see some jitter on it.
The strange thing is that if I hibernate the core, the jitter disappears.
Is this normal, could you tell me why the jitter occurs?
Best regards and many thanks in advance,
