Abstract
The present invention provides a frequency selective circuit, comprising: a voltage-controlled oscillator for outputting a frequency corresponding to the frequency adjustment window; a frequency divider for dividing the clock frequency output by the voltage-controlled oscillator, and feeding back the resulting low frequency to the frequency selection unit; a frequency selective unit for comparing a reference frequency with the resulting low frequency output by the frequency divider, and providing the frequency adjustment window which is configured based on the frequency search window to the voltage-controlled oscillator; a register group for outputting the frequency search window which is provided to the frequency selective unit. The embodiment of the present invention convert the clock frequency from a high frequency to a low frequency. The low frequency is compared with the reference frequency to ultimately find the corresponding low frequency that has the same frequency as the reference frequency.
