Abstract
This paper describes the design of a system used to derive high-speed time signals for SONET/SDH based equipment. This system was combined of three phase-locked loops. After optimized separately, the parameters of the loops were combined together. These three phase-locked loops share the same filter and voltage-controlled oscillator, so the size of the chip is reduced.
