Temperature Compensated Crystal Oscillators (TCXOs)

Low Phase Noise and Low g-Sensitivity TCXOs


TCXOs offer improved temperature stability that cannot be provided by a standard crystal oscillator or Voltage-Controlled Crystal Oscillator (VCXO). This stability is achieved by adding a programmable ASIC or thermistor network, which adjusts the voltage on a varactor to compensate the nominal crystal's frequency vs. temperature curve. The result is a low-power oscillator, with better than ten times improvement in frequency vs. temperature performance.
