E-Tile Transceiver PHY Agilex data rate is 10G, but hssi_ehip_lane_ehip_rate is rate_25gx1

Hello,I configured the E-Tile Transceiver PHY Agilex7 IP ; and the Transceiver configuration rules is Gearbox 64/66 ;mode is TX/RX Duplex. TX and RX PMA data rate is 10312.5Mhz; PMA reference clock f...

Hi Pavee,

The first question: I am using the 10G phy project mentioned above and connecting it to another A10 FPGA's 10G Ethernet (this project ensures no issues). But I found on the STP of A10 that the XGMII signal at the receiving end is unstable, and the received data is not idle data 0x0707 but 0xfefe. So I want to know where went wrong.

The second question is what is the latency of this phy? I have measured that the loopback delay from sending to receiving on the A10 chip's phy was about 130ns, but the PHY Agilex7 IP has already exceeded 300ns.

Regards,
