Nano Atomic Clock (NAC2) Rubidium Frequency Oscillator

NAC2-Ver2-2024.jpg

Product Description

The NAC2 is the newest and smallest addition to AccuBeat’s line of Rubidium Frequency Standards. Incorporating proven traditional glass technology and based on Coherent Population Trapping (CPT), the NAC2 is an extremely small and compact atomic clock that has been designed as a board mounted component. NAC2 provides 10 MHz and 1PPS outputs and short term stability (Allan Deviation) of 2E-11 @ 100 seconds with aging of 3E-10/month at 25°C. The NAC2 has a RS232, format  CMOS compatible, 3.3V@1MΩ, 115200BPS interface for monitoring and control, a Built in Test (BIT) output and a warm up time of less than 130 seconds.  Measuring just 41.1mm X 35.3mm X 16mm and weighing only 38 grams and with power consumption of less than 250mW, the new NAC2 is a Rubidium atomic clock especially suitable and designed for a wide range of portable applications. The NAC2 accepts a 1PPS input that may be used to synchronize the unit’s 1PPS output to an external reference clock with ±100 ns accuracy.
