Abstract: The present invention discloses an Oven Controlled Crystal Oscillator and a manufacturing method thereof. The Oven Controlled Crystal Oscillator comprises a thermostatic bath, a heating device, a PCB and a signal generating element, where the signal generating element is used for generating a signal of a certain frequency, the heating device, the PCB and the signal generating element are mounted in the thermostatic bath, the signal generating element is mounted in a groove formed on one side of the PCB, while the heating device is mounted against the other side of the PCB that is opposite to the groove. The signal generating element may be a passive crystal resonator or an active crystal oscillator. The Oven Controlled Crystal Oscillator according to the invention is advantageous for a small volume and a high temperature control precision.

Abstract: Disclosed are an oven controlled crystal oscillator device and a frequency compensation method thereof. The oven controlled crystal oscillator device includes: an oven, a microcontroller, an oven controlled crystal oscillator disposed in the oven, and a current detection circuit. The current detection circuit is coupled to the oven controlled crystal oscillator, and is configured to obtain an operating current value of the oven controlled crystal oscillator and provide the operating current value to the microcontroller. The microcontroller is configured to determine a frequency compensation amount according to the operating current value based on a frequency compensation rule, and output the frequency compensation amount to the oven controlled crystal oscillator to compensate an output frequency.
