Comtest Technologies, accredited southern African partner to Symmetricom – the world’s leading source of highly precise timekeeping technologies, instruments and solutions in generation, synchronization and distribution of precise time and frequency signals - is proud to introduce the SA.45s Chip Scale Atomic Clock (CSAC) which provides the accuracy and stability of atomic clock technology while achieving dramatic reductions in size, weight, and power consumption. The newest member of Symmetricom’s QUANTUM™ family of atomic oscillators is ideal for portable applications requiring precise synchronization and timekeeping, especially in GPS-denied environments. It is only 16cc in volume, weighs only 35 grams, requires only 115mW of power and is two orders of magnitude more accurate than the more power-consuming quartz-based solutions it replaces.
Atomic oscillators (“atomic clocks”) employ the fundamental physical principles that define world time. When the atoms of certain elements (e.g., hydrogen, cesium, and rubidium are most commonly used) are excited to resonance they emit radiation of a precise frequency. Oscillators that are synchronized to this frequency produce a timing signal that is extremely accurate and stable — much more so than signals produced by crystal-based technology. Symmetricom’s QUANTUM™ family achieves this accuracy and stability in atomic oscillators of extraordinarily small size and low power consumption. These atomic clocks are small enough to be embedded directly on a circuit board, and are ideal for portable applications where size, weight, and power consumption are key issues.
