PLOD260 Digital phase-locked thermostat Crystal Oscillators

Thermostat Crystal Oscillators

The PLOD260 is a high-performance phase-locked crystal oscillator (PLOD260) with three 10MHz outputs and one customizable low-phase-noise 5MHz output in a standard BDSTAR TIME form factor. It integrates a high-performance oven-controlled crystal oscillator (OCR) and a fully digital phase-locked loop (PLL). It supports a 10MHz input and has a bandwidth adjustable from 4MHz to 512MHz via RS-232. It is ideal for optimizing the phase noise and short-term stability of rubidium and cesium clocks.

Important Features

  • Full digital phase-locked loop, built-in high stability and low phase noise constant temperature crystal oscillator
  • Standard construction, height 19mm, stackable mounting
  • Ultra-low phase-noise output: -140 dBc / Hz@10Hz
  • +12~+15VDC power supply
  • 3 way 10M output and optional 1 way 5M output
