一种面向112 Gbit/s SerDes接收机的前瞻滑动判决反馈均衡器
A lookahead sliding decision feedback equalizer for 112 Gbit/s SerDes receiver
摘要
Abstract
With the continuous advancement of information technology,wireline data rates have expe-rienced a significant leap from 112 Gbit/s to 224 Gbit/s.The increase in data rates has raised the com-plexity requirements for SerDes receiver equalizers.To address timing constraints and other issues brought about by complex equalizer structures,a sliding block decision feedback equalizer based on a lookahead structure is proposed.The design incorporates a 6-tap feedforward equalizer(FFE)and a 9-tap decision feedback equalizer(DFE)for digital signal processing.Functional validation is conducted through MATLAB simulation modeling.The results show that at a data rate of 112 Gbit/s,under channel attenuation ranging from 8 dB to 35 dB,this digital signal processing design,which utilizes a least mean squares(LMS)adaptive equalization algorithm,can effectively reduce the bit error rate(BER).The BER performance meets the discrimination requirements of KP4 forward error correction(FEC)and demonstrates superior performance compared to traditional equalizer structures.关键词
