9.13.5. Recommendations for Tuning Link Partner’s Transmitter

This section describes tuning link partner’s transmitter.

To improve the BER of the StratixV receiver, Altera recommends that you turn on Adaptive Equalization (AEQ) one-time mode during Phase 2 Equalization for Endpoints or Phase 3 Equalization for Root Ports. You enable AEQ through the Transceiver Reconfiguration Controller IP Core. For more information about this component, refer to Transceiver Reconfiguration Controller IP Core. For more information about running AEQ, refer to AEQ Registers.

Note: AEQ must be turned off while switching from Gen3 to Gen1 or from Gen3 to Gen2.
