ABSTRACT:
A Phase Locked Loop including a monolithic Phase Locked Loop component. The monolithic component has an internal amplifier stage and an internal VCO. An external phase detector compares the phase of a reference signal to the phase of the output of the internal VCO to provide a signal which is a measure of the phase differences. The signal is filtered by an external filter, amplified by the internal amplifier stage and input to the internal VCO.
