WebJun 25, 2003 · A clock extraction scheme was demonstrated using an optoelectronic oscillator from high-speed nonreturn-to-zero (NRZ) signal. A theoretical model on the locking range of the oscillator was presented. A 10-GHz clock with a timing jitter of 0.4 ps was extracted from 10-Gb/s NRZ signal and a locking range of 800 kHz was achieved. NRZ … WebJul 1, 2000 · The extracted clock is then used to detect the optimal sampling points in the data signal. Therefore, the extracted clock must be synchronized in frequency and in phase with the data signal. The principle of operation of the clock recovery circuit depends strongly on the coding used in the data signal.
