AM572x GP EVM PCIe external clock generator

Other Parts Discussed in Thread: CDCM9102

Hi,

When I measure Pin 21, 2 ,3, 5, 6 of CDCM9102 on the GP EVM, I am not getting any clock. I found All the powers are Ok, RSTOUTn is high.

How can I verify the clock generator is working properly?

Regards,
Hein

Hi,

Is the system running? Do you have anything connected on the PCIe interface?

Hi Hein,
Did you check also pins 7 and 12?

I could see the clock now when I measure after the AC coupling capacitors.
Thanks for your replies.
