Phase locked frequency doubling crystal oscillator adopts phase locked frequency synthesis technology. main feature is that the voltage controlled oscillator in the loop uses a voltage controlled crystal oscillator, which has a better phase noise than the general voltage controlled oscillator. The introduction makes the phase-locked loop have a better remote phase. 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 of the reference signal, which worsens by 20 logN. The phase noise at the end is determined by the phase of the voltage controlled crystal oscillator. Input and output: SMA-K Input signal: 10MHz@0dBm Output signal: 100MHz@14dBm Harmonic suppression: 60dBc Stray suppression: 75dBc Power supply:+12V 5%, current less than 200mA indication: D3 diode is on Without input, the 100MHz signal can still be output, the signal will be about 200KHz higher. Colour:Blue Material:PCB Package Contents: 1 x Phase locked frequency doubling crystal oscillator Only the above package content, other are not included. Note: Light reflection and different displays may cause the color of the item in the a little different from the real thing. The measurement allowed error is +/- 1-3cm.
