DP14 phy used for DP20

Hi,

I have a DP1.4 rx/tx phy in an Aria 10 that has been working well for me. I would like to use the same phy for DP2 at 2.7G. When I send DP1.4 traffic all seems fine, but when I send DP2.0, it appears CDR lock is lost.

Someone mentioned that DP1.4 uses 8b/10b encoding while DP2.0 uses 128b/132b encoding. Is there some configuration/parameter on the twentynm_xcvr_native phy that needs to change?

    Hi,


    DP2.0 currently not supported for A10 device. For now, only S10 is supported.

    you can refer to S10 DP2.0 example design.



    Thank you
