The NAC1 atomic clock is the newest and smallest addition to AccuBeat’s range of rubidium frequency standards. Using proven traditional glass technology and based on Coherent Population Trapping (CPT), the NAC1 is an extremely small and compact atomic clock designed as a board mounted component.

The NAC1 offers both 10MHz and 1PPS outputs and a short term stability (Allan Deviation) of 2E-11 @ 100 seconds with an aging of 3E-10/month at 25°C. The NAC1 has an RS232 interface for monitoring and control, a built-in test output (BIT) and a warm-up time of typically 160 seconds. Measuring just 41.1 mm x 35.3 mm x 22 mm, weighing just 75 grams and consuming less than 1.2 watts, the new NAC1 is a rubidium atomic clock particularly suited to a wide range of wearables applications.
