Abstract :
A novel jitter equalization circuit is presented that addresses crosstalk-induced jitter in high-speed communication links. A simplified model of electromagnetic coupling demonstrates the generation of crosstalk-induced jitter. This model suggests an equalizer that compensates for the data-induced electromagnetic coupling between adjacent links. Additionally, a data-dependent jitter equalizer that provides separate adjustments of rising and falling edge deviations is presented. The circuits are implemented using 130 nm MOSFETs and operate at 5-10Gb/s. The results demonstrate reduced deterministic jitter and lower bit-error rate. At 10Gb/s, the crosstalk-induced jitter equalizer opens the eye at BER of 10-12 from 17ps to 45ps
