Title: Phase-locked loop with fast lock and low jitter
Inventor: COOPER RUSSILL E
IPC: H03L7/087
Filed: 1998-08-13
Granted: 2001-02-11
Abstract: A local generated frequency is brought into synchronization with a reference frequency using a phase-locked loop (PPL) which is configured to operate in a way to reduce the lock time required to achieve synchronization. The PPL includes a voltage-controlled oscillator (VCO) for generating the local frequency in response to an adjustable input control voltage to the VCO, and a phase detector for adjusting the control voltage according to a lack of synchronization between the local frequency and the reference frequency. Initially, a successive approximation process is performed to rapidly adjust the control voltage applied to the VCO in a direction to reduce the frequency offset to the local frequency from the reference frequency and thereby rapidly move toward synchronization therebetween. The phase detector is then enabled to perform a final adjustment of the control voltage to complete the synchronization.
