Abstract :
Decision feedback equalization (DFE) is a popular technique to counteract inter-symbol interference (ISI) in high-speed backplane data communications. Quarter-rate clock timing for DFE circuit design is proposed to alleviate the speed requirement of the clock timing. A receiver implemented in 0.18-μm CMOS technology demonstrates 6.25Gb/s and 8Gb/s operation over a 34" FR4 backplane.
