100MHz Low Phase Noise Crystal Oscillator Frequency Doubled Crystal Oscillator Injection Phase Locked Crystal Oscillator

1. The phase-locked frequency multiplication crystal oscillator adopts phase-locked frequency synthesis technology 2. Its main feature is that the voltage-controlled oscillator in the loop adopts a voltage-controlled crystal oscillator, which has better phase noise than the general voltage-controlled oscillator, which makes the phase-locked loop have better far-end phase generation. 3.

Due to the existence of the loop filter, the phase noise of the phase-locked crystal oscillator at the near end is related to the phase generation of the reference signal, which is degraded by 20logN. The phase noise at the far end is determined by the phase generation of the voltage-controlled crystal oscillator
