ABSTRACT:
A digital frequency generator for producing a pulse output at a specified frequency is disclosed. The circuit is designed to operate in either of two modes in order to obtain high accuracy over a wide range of frequency operation. In a first mode, the circuit merely acts as a frequency scaler producing an output when a counter overflows. In a second mode, a comparator is employed for deciding whether an additional clock pulse delay is necessary to obtain the required degree of accuracy.
