Abstract

The invention discloses a temperature control and temperature compensation oscillation device and a temperature control and temperature compensation oscillation method. When the ambient temperature is in a first range between a first temperature and a second temperature higher than the first temperature, a voltage is provided to the frequency source to reduce a change in frequency of the frequency source due to a change in the ambient temperature. When the ambient temperature is in a second range between the third temperature and a fourth temperature higher than the third temperature, the heater is driven to a target temperature to adjust the operating temperature of the frequency source. Wherein the first temperature is higher than the third temperature.

Description

technical field [0001] The present invention relates to a temperature-controlled and temperature-compensated oscillating device and a related method. Background technique [0002] A quartz resonator applied to a crystal oscillator has a characteristic of greatly changing the oscillation frequency characteristics depending on the temperature. Various techniques have been proposed in order to compensate for such changes to ensure stable frequency characteristics with high accuracy. A conventionally known oven-controlled crystal oscillator is one such technique. [0003] This type of oven controlled crystal oscillator is used to compare the actual temperature with a set temperature, the actual temperature is related to the outside air temperature measured by the temperature sensor, and control the heat source to reduce the difference between the two temperatures, thereby reducing the temperature. The temperature of the quartz resonator housed in the constant temperature furna...
