Linear Equalizer 21Gb/s. The Tektronix LE160 is a Linear Equalizer and supports signal equalization on data rates from 4 Gb/s to 21 Gb/s. 20 dB automatic or manual gain control Integrated variable gain amplifier with differential 50 mV sensitivity Clock-less design transfers incident signal impairments to outputs. No clock to data alignment concerns 9 user adjustable fixed width taps spaced 24 ps apart on the LE160 Fixed tap delay design eliminates external reference clock requirements USB programmable receiver gain and multi UI equalization allows 20 dB of equalization USB programmable channel modeling allows electronic channel emulation USB programmable pre-emphasis and differential outputs amplitude well in excess of 2 V differential USB programmable output duty cycle symmetry control Precision output level controls permit signaling from "œ0" (Return to Zero) well in excess of 2 V differentially User defined presets and stored configurations tailored for key technologies Data input: single-ended Number of taps: 9 physical taps standard with four time-domain mapped taps depending on the data rate Operating data rate range: 4 Gb/s to 21 Gb/s Coupling: AC Max. data input level: 800 mV p-p (typ.)
