The PCS transmit block has the following features.

Transmit buffer management.

8B/10B encoder for PCIe v2.0, DisplayPort, and USB3.0 only. Other protocols contain the encoder in the MAC IP.

Transmit power state finite state machine (FSM).

Low-frequency periodic signal (LFPS)/beacon transmitter (USB 3.0 and PCIe).

Symbol (comma) generator for PCIe v2.0 and USB3.0 only. Other protocols contain the generator in their MAC IP.
