1.8.1.1. PMA Features

PMA channels are comprised of transmitter (TX), receiver (RX), and high speed clocking resources.

The transmit features deliver exceptional signal integrity at data rates up to 58 Gbps PAM4 / 28.9 Gbps NRZ.

Each PMA also has advanced equalization circuits that compensate for transmission losses across a wide frequency spectrum.
