14.7 PCIe Clock
In order to boot up the system smoothly, a PCIe differential clock input is necessary. For example,
a 100MHz differential clock input to J1.43 and J1.45 on DEV-IMX8M-MINI is design to complete
the PCIe function and boot up the system smoothly. If the baseboard does not need the PCIe
function and the designer desire to remove the PCIe reference clock circuit. Please contact the
sales for defining firmware.
The PCIe reference clock design for reference as follow.
