LVDS SERDES

Hi, I have IP serdes in my FPGA (FPGA A) - This SERDES have connection with another FPGA (other board - FPGA B) According to my project requirements - I should inject(output) and get(input) ...

    Hello,

    Thanks for the details. Output clock at FPGA A can be placed at any LVDS pair pins and input clock at FPGA B should be sufficient.

    Thank you.

Hello,

There is not enough information about your design but as far as I understand you can put both in and out in the dedicated pin. I'd advise you to check on both conditions you mentioned to see which one works.

Thanks

    I drew a little VISIO that describe my design :

    My problem is : Unlock / Lock indication is depend by FPGA loading

    I wonder if the root cause is pin location -

    My question is : Should I place both clocks (in & out ) in the dedicated pin clocks or maybe I should do it only for the input clock ?

    Note : I dont have the option to locate input & output to SERDES pin dedicated clocks ( because board planning)

    Thanks
