1.1 PMA

The transceiver lanes include PMA receiver and transmitter sub-modules. These PMA sub-modules include the input and output buffers, signal conditioning circuits, CDRs, and transceiver. The PMA architecture allows the receive and transmit portions of each lane to operate independently. The PMA features are initialized at power-up and can also be altered during device operation using an APB dynamic reconfiguration interface (DRI).

The SmartDebug tool set provides access to dynamic changes of PMA features, including transmit and receive tuning, and receive eye monitoring capabilities.
