Advanced research, cutting-edge engineering and packaging, superior manufacturing and integrated software design all result in embedded atomic oscillators that deliver exceptional performance and unsurpassed accuracy, stability and reliability in the most challenging environments. Combining low drift rates, excellent short-term stability and frequency stability during temperature changes, these oscillators maintain precise frequency and time during extended periods of holdover during GNSS outages or for applications where GPS is inherently unavailable.
Our embedded atomic oscillators are board-mountable and are ideal for portable, battery-powered applications where available power is limited and accurate frequency is required quickly after power-on. With built-in 1 PPS disciplining capability, these solutions deliver atomic clock accuracy combined with low size, weight and power and are ideal for a variety of commercial, industrial, space and defense applications where performance and ruggedness count.
Chip Scale Atomic Clock (CSAC)
- World’s lowest-power commercial atomic clock suitable for power-limited and battery-powered applications
- Fast warm-up time compared to crystal oscillators and extended operating temperature make the CSAC ideal for challenging environments
- Low profile and small footprint suitable for a wide variety of embedded applications

- Clockstudio™ software is a free design tool for CSAC and MAC atomic clocks. It allows you to quickly configure these clocks and collect device telemetry.
Featured Solutions
CSAC-Based GNSS Disciplined Oscillators
Utilize the most accurate time scales in the world for your mobile application with our GPS-2700 GNSS disciplined oscillator. This GNSS disciplined oscillator integrates our CSAC with a high-performance GNSS receiver to provide built-in synchronization with excellent holdover for stability in any type of environment. It comes with features such as low power, temperature stability and a fast warm-up that make it an excellent choice for use in unmanned aerial vehicles, tactical radios and other demanding applications.
Breakthrough LEO Space Applications Use CSAC
The number and variety of LEO space applications for small satellites is growing quickly with many commercial, scientific and defense payloads such as alternative PNT, optical time transfer, inter-satellite communications, RF geolocation, earth observation and interferometry requiring low Size, Weight and Power (SWaP) precision timing solutions. The space Chip Scale Atomic Clock (CSAC) is the industry’s first commercially available radiation-tolerant CSAC ideally suited to providing the accuracy and stability of atomic clock technology while achieving significant breakthroughs in reduced SWaP.
Better Undersea Sensing with our CSAC
Sensors employed in undersea applications rely on precise timing to be effective. However, because time from GNSS is unavailable underwater, these sensors have generally relied on Oven-Controlled Crystal Oscillators (OCXOs) for stable and accurate time stamping within the sensor. Now, these sensors have a better option: our CSAC. Compared to OCXOs, our CSAC maintains higher accuracy for longer periods of time, uses less power and maintains a more stable frequency despite the wide variations in temperature that these sensors encounter.
