This section provides recommendations for correctly configuring the PHY.

The NIDRU processes oversampled data from a PHY, which is usually a SelectIO interface or a transceiver. In this second case, the receiver has to be configured in lock to reference mode, and its auto-adapting equalizer should be disabled by setting these ports to these values:

  • RXCDRHOLD = 1
  • RXLPMEN = 1
