Abstract :
We propose a 4×25Gbps baud-rate bang-bang CDR that incorporates an integrating receiver (INT-RX) to achieve data sampling, eliminating the power overhead from 2x-oversampling. Measurement results demonstrate 25Gb/s error-free operation, 30mW/channel (1.2pJ/bit), and 1.15ps-rms recovered clock jitter.
