摘要

单片自适应电缆均衡器包含一个模拟自适应均衡滤波器，可以精确地合成长度从Om到长度的电缆的逆传递函数，在200 MHz时衰减信号40 dB。这相当于300米的Belden 8281电缆或大约120米的CAT5 UTP电缆。均衡器支持超过400mw的数据速率，并自动补偿不同的电缆长度以及工艺和温度变化。通过200米的Belden 8281电缆以270 Mb/s的速度传输均衡数据后，测量到的峰对峰抖动小于200 ps，这超过了任何单片串行数字视频均衡器的性能。

An adaptive cable equalizer for serial digital video rates to 400 Mb/s

A monolithic adaptive cable equalizer incorporates an analog adaptive equalizing filter that accurately synthesizes the inverse transfer function of cables ranging in length from Om to lengths that attenuate the signal by 40 dB at 200 MHz. This corresponds to 300 m of Belden 8281 cable or roughly 120 m of CAT5 UTP cable. The equalizer supports data rates extending beyond 400 MWs, and automatically compensates for different cable lengths as well as process and temperature variations. The measured peak-to-peak jitter after equalizing data is transmitted through 200 m of Belden 8281 cable at 270 Mb/s is less than 200 ps. This surpasses the performance of any monolithic serial digital video equalizer reported.
