Does a10 transceiver native phy supports 10.3125g datarate when using standard PCS？ how to config it( FPGA 10AX027H4F34I3SG)

it says standard PCS supports 1.0 Gbps to 10.81344 Gbps. but it always reports datarate is not supported Error in IP catalog​ when set 10.3125g using the standard PCS.

Hi,

As I understand it, you have some inquiries related to the 10G data rate support by A10 Native PHY with Standard PCS. For your information, the max data rate supported would be dependent on the core and XCVR speed grade.

As I checked with Native PHY, it seems like the max data rate achievable by your selected part is ~8.9Gbps.

As I tested with part with faster speed grade ie 10AX027H1F34I1HG, the Native PHY is able to achieve the 10.3125Gbps with the Byte SERDES x2 enabled and PCS-PMA interface with = 20 bits.

Please let me know if there is any concern. Thank you.
