25G PCS – 25Gbit/s Ethernet PCS

FPGA Synthesisable 25Gbit/s Ethernet PCS code for ultra-low latency 25Gbit/s connectivity 25GBASE-R

The CT1026-25GPCS IP block simplifies FPGA integration of an ultra fast 25Gbit/s Ethernet PCS Layer in FPGA

IEEE802.3by specification for coding/decoding using 64b66b rules, scrambling with a powerful polynomial and gearbox

Proven on Alpha-Data ADM-PCIE-8V3 board to reduce PCS latency down to 99ns between XGMII and XSBI interfaces.
