  • Digital phase locked loop tuning system
    Patent number: 4121162
    Abstract: A phase locked loop circuit for use in an automatic frequency synthesizing system. The system includes a programmer circuit which is responsive to a channel number input signal and generates a first digital control signal which is representative of the selected channel number and a second digital control signal which is representative of a predetermined group of channel numbers. A programmable divider is controlled by the programming circuit and generates a digital output signal which causes the phase locked loop circuit to generate a desired system output frequency corresponding to the selected channel number input signal. The phase locked loop circuit includes automatic fine tuning and manual fine tuning features.
