crystal controlled oscillator

基本解释

Voltage controlled crystal oscillator(VCXO)plays an important roll in the atomic frequency standard.
压控晶体振荡器是原子频标的重要组成部分。
A circuit called a phase comparator causes the VCO to seek and lock onto the desired frequency, based on the output of a crystal-controlled reference oscillator.
电路称为相位比较器使VCO寻求和锁定所需的频率，基于晶体控制参考振荡器的输出。
