## **AR36CPT series** Coherent Population Trap (CPT) Atomic Clock, Rubidium Oscillator 

## **Description** 

_Abracon’s AR36CPT low phase noise Atomic Clock Oscillator offers the latest Coherent Population Trap (CPT) technology, enabling exceptional performance including tight frequency accuracy, low short-term stability, and reduced power consumption. The Abracon AR36CPT is available in a miniature 45mm x 36mm x 14.5mm package with a CMOS 1PPS and 10MHz output and an input supply voltage of +3.3Vdc. This clock oscillator accepts a 1PPS (pulse per second) input signal that contains extremely accurate time information.  The module locks its 10MHz output to the 1PPS input clock, providing a highly accurate 10MHz frequency reference. Control of the module parameters is performed via UART communications interface._ 

## **Features** 

- CMOS output frequency 10MHz and 1PPS 

- Ultra-tight frequency accuracy ≤5.0E-11 

- Low phase noise high precision atomic clock 

- Operating supply voltage +3.3Vdc 

- Low power consumption <1.6W 

- Voltage control input feature with ±100 ppb range 

- Control functions via UART communication 

- Tight frequency stability ±0.5 ppb typical 

## **Typical Applications** 

   - Satellite Timing and Frequency Communications 

   - Oil, Gas and Underwater Systems 

   - Test and Measurement Instrumentation 

   - Navigation Systems 

   - Telecommunication Infrastructure 

   - Reference for DTV, DAB, VHF, UHF& PMR TX, CMDA, UTMS, LTE, Tetra and IPTV 

- Extended operating temperature range -40 to +70 °C
