Abstract
There is provided a frequency-digital signal conversion circuit for automatically converting a clock frequency into a digital signal. The frequency-digital signal conversion circuit includes: a frequency detecting unit for detecting a frequency of an input clock signal; a latch unit for sampling and latching an output of the frequency detecting unit; and a digital signal generating unit for receiving an output of the latch unit and generating a digital signal of a predetermined bits with respect to the frequency of the input clock signal.
