3.1.7. Loopback modes

Loopback modes are DFT features used to verify different blocks of the transceiver PMA.

E-tile transceivers have loopback modes to debug different blocks of the transceiver. E-tile transceivers support the following loopback modes:

  • Internal serial loopback
  • Reverse parallel loopback
