crystal controlled oscillator

基本解釋

Voltage controlled crystal oscillator(VCXO)plays an important roll in the atomic frequency standard.
壓控晶體振蕩器是原子頻標的重要組成部分。
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.
電路稱為相位比較器使VCO尋求和鎖定所需的頻率，基于晶體控制參考振蕩器的輸出。
