Ethernet 50G PCS IP

Design IP

Overview

SmartDV’s Ethernet 50G PCS (Physical Coding Sublayer) IP Core is engineered to support reliable and high-speed data communication across a wide range of Ethernet-based systems. Fully compliant with IEEE 802.3by and 802.3cd standards, it performs 64b/66b encoding/decoding, lane alignment, deskew, scrambling, and forward error correction (FEC), enabling robust 50G transmission across electrical and optical links.

The IP core supports smooth integration with Ethernet MAC and PMA/PHY layers via standard interfaces such as CGMII and XGMII, making it well-suited for network interface cards (NICs), switches, and routers.

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.

Benefits
