ABSTRACT:
A clock generation circuit for a dual system radio frequency station is provided. The station includes a digital synthesis circuit clocked by a first clock signal for a first RF system that is adapted to generate a base signal output of a predetermined frequency. A second clock signal is derived from the sum of the frequency of the base signal and the frequency of the first clock signal.
