Definitions for "TCXO"
Temperature-compensated crystal oscillator often used often used for frequency control in tactical radios, telecom timing modules (Stratum 3 Type), wireless systems, and reference oscillators.
A kind of oscillator that adjusts the frequency for temperature variation and commonly has an outside adjustment for periodic calibration of frequency. This is to compensate for the aging of the crystal over time.
