Abstract:Significant performance improvements have been obtained with a 40 Gb/s phase-locked clock recovery (CR) module for fiber optic receivers by employing a new frequency acquisition circuit in the phase-locked loop (PLL) and a clock hold circuit. The new simple frequency acquisition circuit helps to extend the frequency lock-range, obtain faster frequency acquisition, and reduce the current consumption as compared with the conventional ones. In addition, a clock hold circuit helps to prevent the loss of the clock … Show more
