Ethernet 100G PCS
Design IP
Overview

SmartDV’s Ethernet 100G PCS (Physical Coding Sublayer) IP Core is designed to meet the rigorous demands of high-speed data transmission across networking and communication systems. Compliant with IEEE 802.3bj and 802.3cd standards, it performs essential functions such as 64b/66b encoding and decoding, lane distribution and alignment, deskew, and forward error correction (FEC), ensuring reliable and efficient data transport at 100Gbps.

The IP core supports multiple Ethernet rates including 25G, 50G, and 100G, enabling flexibility in building interoperable, scalable multi-rate systems. Its modular architecture simplifies integration with 100G MAC and PMA/PHY layers through standard interfaces like XGMII, XLGMII, and CGMII.

Designed for flexibility, the IP core is highly configurable to meet specific design requirements, supporting both ASIC and FPGA implementations while optimizing for area, power, and performance. Proven on FPGA platforms, the 100G PCS IP offers low-latency performance, making it ideal for high-throughput applications in data centers, carrier networks, and advanced industrial systems.
