New Method for 100MHz High Frequency Temperature Compensated Crystal Oscillator.

The implementation of high performance and high frequency temperature compensated crystal oscillator still faces great challenges. In this paper, a new temperature compensation method for HFTCXO with closed-loop architecture is described. The sample of 100MHz HFTCXO with the measured temperature stability of ± 0.22ppm/-40 ∼ +85 °C and the phase noise of -151dBc/Hz@1kHz and -163dBc/Hz@10kHz was designed. Experimental results show that this method can realize real-time high-precision temperature compensation of high frequency crystal oscillator.
