ABSTRACT:
In a transceiver, a synthesizer includes a multiposition switch which accesses various addressable memory locations in a programmable read-only memory (PROM), where the appropriate divisors are stored to cause tuning of the synthesizer to the appropriate communication channel. A zone selector switch enables grouping and easy retrievability of channels. The divisors are supplied to a single synchronous binary swallow counter which works in conjunction with a dual modulus prescaler to monitor the frequency output of the voltage controlled oscillator. In the swallow counting device, two latches receive divisor related information supplied by the PROM. When the sampled state of a single up counter reaches a first latched number, the prescaler changes the modulus. Synchronous counting then continues, without reprogramming new values. When the up counter reaches a second latched number, a predetermined frequency ratio has been achieved, and the counter is reset.
