Embodiment Construction
[0024] The embodiment of the present invention provides a technical solution to improve the reliability of the temperature-compensated oscillator when the current components have a long working time, a high frequency of use, and a small user terminal single board.
[0025] It should be noted that the embodiments of the present invention are applicable to various temperature-compensated oscillators. Since the principles are basically the same, the following only takes the temperature-compensated voltage-controlled oscillator VCTXO as an example for description.
[0026] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by...

An embodiment of the invention discloses a method for increasing the reliability of wireless terminal temperature compensation oscillator and a device thereof. The wireless terminal comprises a plurality of temperature compensation oscillators which are respectively corresponding with different operating modes of wireless terminal. Each temperature compensation oscillator is positioned on the area with low temperature on the single board in the corresponding operating mode. The method of the invention comprises the following steps: confirming the operating mode of wireless terminal; and enabling the temperature compensation oscillator corresponding with the operating mode. The embodiment of the invention also provides a method for laying the temperature compensation oscillators. The embodiment of the invention aims at different operating modes and selects the temperature compensation oscillator in the area with lower temperature in the operating mode thereby preventing the condition that the temperature compensation oscillator can not normally operate because of overhigh temperature rising at the position of the temperature compensation oscillator in a certain degree, and increasing the reliability of temperature compensation oscillator.
Description
Technical field [0001] The present invention relates to the technical field of terminals, and more specifically, to a method and device for improving the reliability of an oscillator and a method for arranging the oscillator, in particular to a voltage-controlled temperature-compensated crystal oscillator (Voltage Controlled Temperature Compensated Crystal Oscillator, VCTXO) Reliability method and device, and method of deploying the VCTXO. Background technique [0002] With the development of wireless communication technology, user communication terminals have become more and more powerful, from early telephone voice services to current data services such as video phones. In addition, with the development of GPRS-EDGE-WCDMA-HSDPA and other technologies, the data download capability of communication terminals has gradually improved. In addition, the use of large-capacity batteries makes the continuous use time of communication terminals longer and longer. [0003] The above condit...
