SmartDV’s Ethernet 40G PCS IP is a silicon-proven, fully featured Physical Coding Sublayer solution purpose-built for SoC designs requiring reliable 40 Gigabit Ethernet connectivity across networking switch, router, and data center applications. Fully compliant with IEEE 802.3-2022 Clause 82, it delivers complete 40GBASE-R and 40GBASE-KR4 PCS functionality with 64b/66b encoding and decoding, distributing data across 4 lanes for backplane and copper configurations.
Designed to address the practical signal integrity requirements of modern 40 Gigabit Ethernet interconnects, the IP implements complete 64b/66b encoding and decoding for both transmit and receive paths, data scrambling and descrambling, 4-lane distribution architecture, block synchronization, gearbox functionality for various data widths, alignment marker insertion and removal, per-lane BIP-8 insertion and checking for bit error rate monitoring, and optional Fire Code FEC per IEEE 802.3-2022 Clause 74 for backplane and copper cable channels. Its loopback functionality, receiver link fault status detection, and IEEE 802.3az Energy Efficient Ethernet support give networking SoC teams a production-tested, spec-complete 40G PCS implementation.
Built for design flexibility and silicon efficiency, the IP core is highly configurable for both ASIC and FPGA implementations, with a strong focus on area optimization, power management, and peak performance. Its parameterized PMA interface architecture and clean host interface enable fast integration across a wide range of networking process nodes.
