Abstract :
ICs for optical data links have been developed for bit rates between 10 and 200 Gb/s. The only exception was the clock recovery (CR) IC at these high bit rates. In fact, the IC realization of CR is generally accepted as the weak point of high-speed system integration. While the bit rates of some ICs reach up to 40 Gb/s, monolithic ICs for a full CR function are limited to 2.5 Gb/s. The monolithic IC described here, for CR with a PLL including a full-balanced VCO, is based on the IC reported by Wang et. al. (1993). Clock frequencies up to 19 GHz are recovered with the IC reported here.<>
