12.1.1. PMA Features in E-Tile Transceivers - The transmitter, receiver, and high speed clocking resources form the PMA channels. The transmit features deliver exceptional signal integrity at data rates up to 58 Gbps PAM4 or 28.9 Gbps NRZ. Additionally, each PMA features advanced equalization circuits that compensate for transmission losses across a wide frequency spectrum.
