PLOA260 Analog Phase-Locked Thermostatic Oscillator

Analog phase-locked thermostat Crystal Oscillators

PLOA260 is a low noise analog phase-locked oscillator which is based on the standard form factor design of BDSTAR TIME, and integrates 1 high performance thermostatic crystal, 1 digital phase-locked loop and 3 isolation amplifiers, and also can be Customized with 1 low phase noise 5MHz crossover output, 5Hz fixed bandwidth filament, 1Hz phase noise, and 1s fixed degree following standard. While the far end noise is determined by the local low noise crystal oscillator, the PLOA260 can be used to optimize the output noise of the clockkeeping room phase trimmer, and is suitable for connecting to the hydrogen clock set phase trimmer, which improves the phase noise performance while maintaining the hydrogen clock second stability
