  • Circuit for limiting jitter transients during switching of phase control signals to an oscillator
    Patent number: 4600896
    Abstract: A phase comparator is included with each incoming channel to compare the clock phase of the incoming signal and a local oscillator. The phase comparator of an on-line active unit generates a signal to control the oscillator to maintain its output in phase with the incoming signal. The generated control signal is also connected to capacitor storage in associated channel phase comparators to provide them with an initial starting control voltage when they are switched in to be the receiving channels. Thus eliminating the uncontrolled operation of the oscillator during switching interval.
