低功耗小型化时频模块的设计

Design of Low Power Miniature Time-frequency Module

随着科技的发展,高精度时间基准被广泛应用于通信、导航、电力、工业、商务以及国防建设等重要领域,精确的时间同步需求也越来越广泛,对时间和频率基准的精度提出了越来越高的要求,如何获得高精度时间同步是保障各系统正常可靠运行的关键。对于时间频率用户系统来说,在利用各种技术手段获得高精度、高可靠性的时间频率的同时,时统用户终端的体积、功耗等也成为更加关注的目标。研制低功耗、小型化的时间模块,可以有效解决时间频率用户系统性能指标与体积、功耗之间的矛盾,便于实现时间源的冗余备份,更大程度提高时统设备的可靠性。

With the development of science and technology, the high accuracy time benchmark is widely used in communications, navigation, electricity, industry, business and national defense construction and other important areas, precise time synchronization requirements also more and more widely, with time and the precision of frequency standards higher and higher demands are proposes. How to obtain high precise time synchronization is the key to guarantee the system normal and reliable operation. For time and frequency user in using various technical means to obtain high accuracy, high reliability, time frequency at the same time, the volume of the system when the user terminal, power consumption has also become more focused on goals. Developed low power miniaturization time module can effectively solve the contradiction between the time and frequency user system performance index and mass. It can be easy to realize time source redundancy backup, when a greater degree to improve the reliability of the system equipment.
