Abstract :
A 2 V clock synchronizer chip using digital delay-locked loop is presented. It is targeted to provide synchronous clock distribution in high-speed digital systems. A simple structure with a counter-based delay line is used for compensating the skew caused by process, voltage, temperature and length. A stability criterion is also obtained. Experimental results have demonstrated its advantages like good stability, wide tuning range and low power consumption
