Queries on 46.6944 Gbps PAM4 F-Tile Configuration and Loopback Testing using Agilex7

Hi,

Regarding the external loopback BER results, I apologize, but I was unable to locate the specific test results and configuration details that you are referring to.

In general, the target BER requirement depends on your system design and the protocol specifications being used. Therefore, we recommend reviewing your system-level and protocol-level BER requirements to determine the appropriate target value.

If additional link optimization is required, you may consider performing manual PMA tuning using the Transceiver Toolkit (XCVR Toolkit). For more information, please refer to the F-Tile Architecture and PMA and FEC Direct PHY IP User Guide, specifically the "Debugging F-Tile Transceiver Links" section, which provides guidance on transceiver link debugging and tuning.

Please let us know if you have any further questions or require additional assistance.

Thank you.
