Precision Devices - OCXO with low phase noise and tight stability
Precision Devices has announced the introduction of a new low noise oven controlled crystal oscillator, the OCXO-100 series. The new oscillator is manufactured at Precision Devices production facility in Cambridge, England and is produced using AT-cut or precision SC-cut crystal technology. The Precision Devices OCXO-100 series offers very low phase noise options with a square wave TTL/HCMOS or Sine wave output and is available in frequencies fr...
New ultra low noise, ultra stable OCXOs from Precision Devices
At European Microwave Week, Precision Devices has announced the OCXO-510, an ultra low noise and ultra stable crystal oscillator (OCXO). The OCXO-510 series has a phase noise floor of -168dBc at 10 kHz. It offers excellent stability, and operates at a precision of only 0.0002ppm (or 0.2ppb – parts per billion) over a temperature range of 0 to +70C or 0.0005ppm at -20+70C.
