Abstract :
A 1.25-Gb/s clock recovery (CR) circuit for Very Short Reach (VSR) OC-192/STM-64 parallel optics interface is realized based on a phase- and frequency-locked loop. The test CR IC achieves a wide locking range from 1.03 GHz to 1.42 GHz, a small rms jitter of 4.62 ps (0.00368 UI) for a pseudorandom bit sequence (PRBS) length of 231-1. The DC consumption is 132 mW.
