摘要：An adaptive cable equalizer includes a data signal input unit, a clock signal inputunit, a variable equalizer that inputs a data signal input from the data signal input unit,and a transition time measuring portion that measures a transition time of a data signaloutput from the variable equalizer, with an equalizer control loop being configured that

controls characteristics of the variable equalizer based on the output signal of thetransition time measuring portion. The adaptive cable equalizer further includes a controlcircuit that controls response characteristics of the control loop according to thefrequency of a clock signal input from the clock signal input unit. This enables a quickresponse at fast transfer rates by making the relationship between the response time ofthe control loop and the number of data bits substantially constant even when thetransfer rate changes from a slow transfer rate to a fast transfer rate.
