ocxo meaning in Chinese

恒温晶振

In case of absence of a precision external reference , the ocxo frequency adjustment is carried out by means of the p1 potentiometer
万一一个精密度的外部参数缺省， ocxo频率调整依靠p1电位计来实行。
The designs of the pfd , digital filter ocxo and fractional - n counter in the frequency synthesizer unit are discussed , based on the pll theory . in order to improve the precision of pll , some design methods of pfd are given , and its feasibility is validated by the fpga hardware implement
2 .在锁相理论指导下,第三章讨论了频率合成器设计中的鉴频鉴相器、数字滤波器、恒温压控振荡器和分频电路设计。为了进一步提高频率合成的精度,文中给出了提高鉴频鉴相器性能的一些设计思想,结合fpga的硬件设计验证了其可行性。
