Understanding audio MC clocking
Posted: Mon May 29, 2017 2:11 pm
I'm using the audio MC board as reference for an USB analog audio input board. As far as I can tell the MC board uses a single 24MHz crystal as master clock for xcore system clock (as required by the USB phy). The same crystal is also used as the audio master clock via a PLL chip.
My question. Is there anything that prevents using two different crystals, e.g. a 24MHz for xcore system clock and another (24.576MHz) for adc and xcore_mclk?
Thanks /Jorgen
