Hello Team,

Please help to review the schematic section of LMK00334(1 :4 PCIe clk buffer) attached herewith.

My requirement is to derive 3 refclk outputs from a single CLK input.

Kindly confirm, whether the implementation works to meet the above requirement or not.

Hi Yasar,

I took a look over your schematic and it looks good. The only question I have is regarding your REFOUT signal. You have REFOUT_EN wired low, which will put REFOUT in a Hi-Z state. You have a test point attached to REFOUT, so I just wanted to ask if you were expecting an output there?

Thanks,

Michael

Hi Michael,

Thanks for the feedback.

I just put a TP on REFOUT, that's all, not any specific requirement with this. Anyway, I have given a strapping option provided on "REFOUT_EN".

My only intention with this implementation is getting 3 buffered outs from a single input.

If this requirement meets means I am ok.

Hi Yasar,

In that case, your schematic is good.

Thanks,
