Ethernet 800G PCS IP – SmartDV

Ethernet 800G PCS IP

Design IP

Overview

SmartDV’s Ethernet 800G PCS (Physical Coding Sublayer) IP Core is engineered to deliver robust and efficient data encoding, alignment, and error correction for ultra-high-speed Ethernet systems. Compliant with IEEE 802.3ck and 802.3df specifications, it supports essential PCS functionalities such as 64b/66b encoding/decoding, FEC (Forward Error Correction), lane distribution and alignment, and deskew for 800G Ethernet links.

Designed to interface seamlessly with 800G MAC and PMA layers, the IP core supports industry-standard interfaces including 800G CMAC, CGMII, and PAM4-based PHY interfaces. Its modular architecture ensures easy customization and integration across diverse high-speed networking environments.

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. This makes it a powerful building block for future-proof Ethernet platforms across cloud-scale networking, AI/ML fabrics, and high-performance computing environments.
