Tektronix - LE160

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 “0” (Return to Zero) well in excess of 2 V differentially

User defined presets and stored configurations tailored for key technologies
