3.1.1. Transmitter PMA
Parallel data received from the EHIP_LANE, EHIP_CORE, RS-FEC, and PMA Direct is serialized by the serializer. This serialized data is de-emphasized to compensate for the intersymbol interference (ISI) losses using an equalizer. The transmitter buffer at the end of the PMA data path shapes the signal and drives the serialized data off the chip.
