GIGABIT ETHERNET PCS

The Gigabit Ethernet PCS module implements the Physical Coding Sublayer (PCS) of the Gigabit Ethernet protocol stack. The protocol stack is shown below. The PCS functionality includes: Transmit, Synchronization, Receive and Auto-Negotiation. For functional description and a block diagram, please refer to the PCS module Data Sheet

The PCS module is an important part of any Gigabit Ethernet implementation – more so than would appear from a casual glance at the protocol stack diagram. For more detailed explanations, please refer to our Application Note

Implementation

The PCS module is available as either Verilog or VHDL source code. The design has a modular structure. The well-commented, self-documenting source code is easy to read and understand. The design has been extensively simulated and tested. The simulation test bench written in VHDL or Verilog is provided with the module.

Applications

The Gigabit Ethernet PCS module can be useful in many applications, as shown in the Application Note. TRILENT Networks’ flexible licensing supports cost effective implementations.
