The 222 Series from MTI-Milliren is a range of rugged OCXOs for demanding military applications such as UAVs, rotorcraft, and tracked vehicles. These OCXOs are especially designed for applications that require significantly reduced acceleration sensitivity which can’t be obtained through conventional solutions. They have low G sensitivity of less than 2.0 E-10/g /axis with a high resolution digital tuning interface via 24-bit DAC for tuning I2C and have low static phase noise. The OCXOs are available in a hermetic package measuring 1.0 x 1.0 x .565 inch.
