TCXO
Temperature Compensated Crystal Oscillators
Overview
For applications requiring temperature stability levels that a standard XO or VXCO cannot achieve, Microsemi offers a variety of temperature compensated crystal oscillators (TXCOs). TCXOs use multi-order temperature to voltage transducers to compensate for the frequency versus temperature effects of the crystal, and consume only a few milliamps while maintaining stabilities of 1E-7. Portfolio options include low g-sensitivity and low noise TCXOs, microprocessor corrected TCXOs, space-qualified TCXOs and Stratum-3 TCXOs.
