Hello, I am designing a custom board using i.MX8MM.
There are four different ICs that need External Xtal for proper operations.
KSZ9131RNXC Ethernet PHY needs 25 MHz Clock Input.
DSI to HDMI converter needs 25MHz clock Input.
USB HUB needs 12 MHz clock input.
Do I have to use external XTAL for all ICs or can I provide the necessary clock input from i.MX8MM CCM outputs.
From the application note what I understood The SoC can provide external clock output using
CCM pins. Is that possible to provide all these clock inputs from these pins and how can I set them
And Do you have any idea about clock integrity as a PPM
