LN CSAC GPS Disciplined Oscillator

The LN CSAC GPSDO combines the Cesium Vapor Cell reference oscillator with an ultra-high-precision, ovenized, SC-cut crystal oscillator for ultra-fast warmup, excellent holdover, low power, exceptional Phase Noise and Allan Deviation (ADEV) performance in the xE-012 range. The combination of the relative strengths of both oscillators results in an overall package capable of competing with the highest performance, commercially available Cesium Reference clocks, with a price point much lower than legacy products. The LN CSAC offers GPS Disciplined, exceptional phase noise, ADEV, holdover performance, extremely low power consumption, and very small size.

The LN CSAC GPSDO is form, fit, and function compatible to the popular CSAC GPSDO boards, and does not require any design-in changes for customers upgrading from the standard CSAC GPSDO platform.

Highlights

• Ultra Low Noise SC-cut post-filter
• 110 dBC/Hz at 1 Hz Phase Noise
• 1E-012 ADEV stability at 1 s
• Built-in distribution amplifier

Applications

The LN CSAC has very low phase noise and high ADEV performance, making it ideal for many Radio applications such as:

• Radar transmitters, Radar front-ends
• Astronomy applications
• Test equipment references
• Ultra low phase noise Ka, Ku, C band up and down-conversion for Sat communications
• Manufacturing testing of crystal, oscillators (TCXO, OCXO, Cesium, Rubidium)
• High entropy radio communications
• House/Lab time and frequency standards
• Military high-grade jammers and spoofers
