Abstract :
A new method has been developed to drive a single quartz crystal in both of its modes. Using a modulator and a demodulator the oscillator provides a C mode frequency output directly as well as the difference frequency between the C and B modes. Results concerning this dual-mode oscillator used in a digital temperature compensated quartz crystal oscillator (DTCXO) are reported.
