Abstract :
In this paper, a burst-mode CDR circuit is presented that achieves output-data- jitter reduction of 3dB at jitter frequency of 1 GHz, synchronization to the input data within 14 bits of the burst input, and tolerance to pulse-width distortion (PWD) of +0.22/-0.32UI at 10.3125 Gb/s operation. These characteristics are provided by a CDR architecture with jitter-reduction and PWD-compensation circuits.
