Ethernet Cyclic FEC IP
Design IP
Overview

SmartDV’s Ethernet Cyclic Forward Error Correction (FEC) IP is a silicon-proven solution that enhances data integrity and reliability across high-speed Ethernet links. Fully compliant with IEEE 802.3 specifications, it implements the (2112, 2080) shortened binary cyclic Fire code derived from the (42987, 42955) parent code and supports 32-bit parity generation. The IP core can detect and correct burst errors of up to 11 bits, making it ideal for demanding environments such as automotive Ethernet, 5G backhaul, and high-throughput industrial systems.

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. It integrates seamlessly into Ethernet MAC or PHY subsystems to minimize retransmissions and maintain low-latency communication.

Ethernet Cyclic FEC
Benefits
  • Improved Link Reliability – Implements Cyclic Forward Error Correction (FEC) to detect and correct transmission errors, ensuring robust data integrity across Ethernet links.
  • Optimized for up to 100 G Ethernet – Designed for medium-to-high-speed Ethernet applications requiring low-latency, high-reliability communication.
  • Efficient Error Recovery – Corrects up to 11-bit burst errors using a (2112, 2080) shortened cyclic code derived from the Fire code (42987, 42955).
  • Low-Latency Architecture – Utilizes a pipelined correction mechanism to maintain high throughput with minimal latency overhead.
  • Seamless System Integration – Compatible with standard Ethernet MAC and PCS layers, simplifying integration into existing SoC architectures.
  • Reliable Data Synchronization – Incorporates a bit-locking mechanism for stable link recovery and consistent data alignment.
