A folded multitap transmitter equalizer and multitap receiver equalizer counteract the losses and reflections present in the backplane environment. A flexible 2-PAM/4-PAM clock data recovery circuit uses select transitions for receive clock recovery. Bit-error rate less than 10-15 and power equal to 40 mW/Gb/s has been measured when operating over a 20-in backplane with two connectors at 10 Gb/s.
