because the 10G(XFP) optical module with the CDR circuit,the 1.25G,2.5G optical module without,so i want to add the CDR on the PCB,but i must remove the CDR when i insert the 10G optical module.
if we used like this,there are tap on the pcb layout,it will affect the signal integrity,so ,we want to add CDR on the other port,just like fangquan said.
can you send the following documents to me or fangquan?

schematic symbol of ADN4612 and ADN2915
