Abstract
This paper describes a board-level realization of 2.5 Gb/s clock and data regenerator circuit, where the clock recovery function is implemented by a phase locked loop configuration. In order to use a low cost commercially available voltage controlled oscillator (VCO) a Richman quadricorrelator frequency-difference discriminator has been designed. The resultant frequency and phase locked loop (FPLL), makes possible the frequency acquisition even if the VCO starting frequency were out of the PLL pull-in range. All components used are cheap commercially available silicon devices. Measurements, at 10-9 bit error rate, give an input electrical sensitivity less of 5 mVpp with 223-1 pseudo-random input data stream. The recovered clock jitter is compliant with SONET STM-16.
