摘　　要：为解决卫星通信系统中,多设备需同源的问题,文章设计了一种具有8路输出的10 MHz参考源,其时钟基准源既可以是外部输入参考时钟,也可以是内部恒温晶振源,并优先选择外部输入参考时钟作为其基准源。在选择外部输入参考时钟作为基准时,本设计会关闭内部恒温晶振的电源,以达到节省功耗的目的。In order to solve the problem of multiple devices requiring the same source in the satellite communication system,a 10 MHz reference source with 8 outputs is designed here.The clock reference source can be either an external input reference clock or an internal constant temperature crystal oscillator source.And preferentially select the external input reference clock as its reference source.When the external input reference clock is selected as the reference,this design will turn off the power of the internal constant temperature crystal oscillator to achieve the purpose of saving.

关 键 词：载波检测 10 MHz参考源 8路输出
