The chip scale atomic clock (CSAC) represents a significant advancement in timekeeping technology, offering atomic clock accuracy in a compact, low-power package. CSACs utilize miniature physics packages, such as those based on coherent population trapping (CPT) or optically pumped vapor cells, to achieve frequency stability and precision comparable to traditional atomic clocks but at a fraction of the size and power consumption. This makes them ideal for applications where size, weight, and power (SWaP) constraints are critical, such as in portable navigation devices, unmanned aerial vehicles (UAVs), and wearable technology.

Chip Scale Atomic Clock (CSAC) | Ultra-Precision Timing Solution

 Next-Gen Atomic Clock Technology for Space-Constrained, High-Reliability Systems

California Triangle is a leading time-frequency technology company specializing in Chip Scale Atomic Clocks (CSACs) that deliver ultra-precise, low-power, and compact timing solutions for mission-critical applications.

As one of the few global suppliers with full-stack self-developed atomic clock chip technology, we enable synchronization accuracy at picosecond (PS) levels—empowering next-gen GNSS-denied navigation, military communications, industrial IoT, and timing-critical telecom networks.

 What Is a CSAC (Chip Scale Atomic Clock)?

A CSAC is a miniaturized atomic clock that integrates advanced rubidium or cesium frequency reference technology into a chip-level form factor. It offers:

• Ultra-small size: Ideal for portable or embedded applications

• Ultra-low power consumption: Perfect for battery-powered systems

• High long-term stability: Better than quartz oscillators

• Autonomous timing: Works without GPS signal
