The IQRB-4 Rubidium Oscillator from IQD is a Sub-Miniature Atomic Clock that operates at 10 MHz. It has an excellent frequency stability of ±0.05 ppb. This oscillator has a low power consumption of less than 6 W @ 5 V power supply and draws 800 mA of current. It has a phase noise of -148 dBc/Hz @ 100kHz and provides CMOS or Sinewave (available on request) outputs.
This RoHS-compliant oscillator is available in a small form-factor, OCXO style package that measures 50.8 x 50.8 x 25.0 mm. It is suitable for Stand-alone frequency source, synchronisation of or as reference for satellite & secure communications, navigation systems in financial, utility, security, and communications timing applications.
