A Study of Forward Error Correction Codes for SAS Channels

This paper evaluates the performance of several choices of Reed-Solomon code and shows how a frame-interleaved RS(30,26) code can achieve 1e-15 bit-error rate (BER) in the presence of burst errors. See the authors conclude that, as data rates go higher, current 128b/130b encoding is not a good option as the two-bit 01/10 overhead suffers due to its Nyquist pattern property.

Outer Loop Equalization for PCIe Cross-Lane Transceiver Optimization

PCIe Gen4 Standards Margin-Assisted Outer-Layer Equalization for Cross-Lane Optimization in a 16GT/s PCIe Link

PCIe Gen4 enables new wave of innovation to guide inner-loop SerDes optimization assisted by outer-loop system optimization. This paper introduces an outer-layer equalization scheme for managing SerDes inner-layer equalization to optimize overall system-level aggregate performance.
