AM5728: PCIe Clock

Feng Dong

Part Number: AM5728

Hi，

Can AM5728 generate 100MHz clock (PCIe reference clock) (am5728 works as a RC) for endpoint in FPGA? if so, how to generate 100MHz clock? thanks

Hi Feng,

As a disclaimer, by default in our boards we use an external clock generator, and SDK default is to also use the external clock generator, so most likely TI has not validated using the internal reference clock from AM57x to generate the 100MHz clock.

However, looking through some past E2E, it does seem to be possible. I would recommend referencing this thread: https://e2e.ti.com/support/processors-group/processors/f/processors-forum/683424/linux-am5728-pcie-output-clock-configuration
