ABSTRACT:
A unitary phase and frequency adjust network for use in a multiple frequency digital phase-locked loop circuit is described. The unitary phase and frequency adjust network utilizes a single circuit to effect both phase and frequency adjustments. The multiple frequency digital phase-locked loop effects phase adjustments by selectively combining or subtracting a reference clock signal with a derived programmable clock signal thereby generating a composite digital phase-locked loop clock signal. The phase and frequency adjust network effects frequency shifts by selectively adding or subtracting pulses from the composite clock signal at a rate determined by a programmably controlled clock signal.
