MTI Unveils NextGen Cesium Atomic References for Military & Airborne Applications

MTI (MTI-Milliren Technologies Inc) has introduced next generation of atomic references for rugged military and airborne applications. It combines Cesium Atomic Clock performance with MTI’s patented Low G sensitivity DOCXO in a small outline hermetically sealed package. The Precision Reference generates a highly accurate frequency (typically better than 5E-11 after 24hrs) with very low phase noise performance in dynamic environments.

The device is also capable of locking to an external frequency reference or GPS. The entire assembly uses less than 16 W at -40°C (total continuous power) and offers a fast warm-up of less than 9 min with an accuracy better than 4E-10 at -40°C (reference time 30 min.). RS-422 provides communication, control and status reporting along with wired RS-422 level status outputs. Thermal interface allows for use with minimal direct airflow such as encountered at high altitudes. Multiple options are available to offer a customized, high performance next generation Atomic Frequency Reference.

Electrical Performance and Features:

  • Frequency Outputs: 5 MHz (qty 3) & 80 MHz (qty 7)
  • Supply Voltage: 12 VDC and 15 VDC
  • Warm Up Power Consumption: 12 VDC, 24 W Max. ; 15 VDC, 4 W Max.
  • Continuous Power Consumption: 12 VDC, 12 W, 15 VDC, 3.75 W @ -40 °C
  • Operating Temperature: -40 to +71 °C, Non-Operating -55 to 90 °C
  • Temperature Stability: ± 4.5E-10 (Reference=Internal Cesium)

Applications Include:

  • Low G Sensitivity for rugged military applications
  • Airborne and Shipboard
  • Ground and Satellite Communications
  • Secure Communication Links
  • Rubidium Clock Replacement
