Abstract

A crosstalk cancellation and signal reutilization (XTCR) analog front-end implemented with infinite impulse response (IIR) networks dramatically improves signal integrity across multiple closely-spaced single-ended PCB traces. The XTCR technique has been designed to address multiple high-speed I/Os from the ground up. To verify this technique a 4 channel prototype was implemented in 65 nm CMOS. This 4 channel prototype design handles crosstalk cancellation for single-ended I/Os operating at 12 Gb/s. At this speed, the prototype XTCR design improves the measured average horizontal and vertical-eye openings by 37.5% and 26.4% at 10-8 BER, while consuming only 0.96 pJ/b/lane.
