Abstract

A clock generating device includes a divisor register, a reference clock generator, a first counter, a second counter, and a delay regulator circuit. The divisor register provides a divisor. The reference clock generator outputs a reference clock signal. The first counter counts a first number of cycles of the reference clock signal and generates a first count. The first counter outputs a first clock signal according to the first count and the divisor. The second counter counts a second number of cycles of the first clock signal and generates a second count. The second counter outputs a second clock signal according to the second count and a coefficient. The delay regulator circuit determines whether to control the first counter to delay outputting the first clock signal according to the first clock signal.
