Abstract
본 발명은 주파수합성회로에서 호핑되는 채널주파수의 안정화시간을 단축하여 고속으로 채널을 스위칭할 수 있는 회로를 제공한다. 이를 위하여 본 발명은 위상 고정루프 방식으로 원하는 대역의 국부발진 주파수를 발생하기 위한 국부발진 주파수 발생수단과, 채널 지정데이타를 수신하며 디지탈 합성수단을 이용하여 지정된 채널지정주파수를 발생하는 수단과, 상기 국부발진주파수와 상기 채널주파수를 합성하여 지정된 채널로 호핑된 주파수를 고속으로 발생하는 수단을 구비한다. 따라서 채널주파수를 변경할 시 디지탈합성수단에서 발생하는 채널지정주파수의 안정화시간으로 원하는 채널주파수를 발생할 수 있다.The present invention provides a circuit capable of switching channels at high speed by shortening the stabilization time of a channel frequency hopping in a frequency synthesis circuit. To this end, the present invention provides a local oscillation frequency generating means for generating a local oscillation frequency of a desired band in a phase locked loop method, means for receiving channel designation data and generating a designated channel designation frequency using digital synthesis means; Means for synthesizing the local oscillation frequency and the channel frequency to generate a high frequency hopping frequency to a designated channel. Therefore, when the channel frequency is changed, the desired channel frequency can be generated by the stabilization time of the channel specified frequency generated by the digital synthesis means.
