ABSTRACT:
A frequency generator circuit which provides an output signal which is both synchronous with and proportional in frequency to a clock signal of predetermined frequency in response to an input control signal is provided. A frequency divider portion couples a clock signal of divided frequencies to predetermined control electrodes of series-connected switches which selectively couple an output node to a reference voltage node. A decode portion selectively bypasses predetermined switches in response to the input control signal to selectively couple the reference node to the output node. A latch is coupled to the output node to hold the decoded output signal at a predetermined logic level for a predetermined amount of time.
