Ethernet 200G PCS IP

Design IP

Overview

SmartDV’s Ethernet 200G PCS (Physical Coding Sublayer) IP Core delivers the critical encoding, alignment, and error correction functions required for ultra-high-speed Ethernet communication. It complies with IEEE 802.3bs standards and supports PAM4-based signaling for reliable 200G data transmission across high-speed serial links.

The IP performs 256b/257b encoding and decoding, lane mapping and alignment, FEC encoding/decoding, and deskew functionality. It supports a variety of PHY interfaces, including CGMII and 200G PMA, enabling seamless integration into multi-lane Ethernet architectures.

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. Its modular structure and high configurability make it ideal for 5G backhaul, hyperscale data centers, and other bandwidth-intensive environments.
