指针式石英电子钟具有走时准确、耗电省、式样美观新颖、使用方便等特点。机械钟有被指针式石英电子挂钟、台钟、闹钟、旅行钟等所代替之势。指针式石英电子钟用集成电路大致可分为三大类:低频石英电子钟电路;高频石英电子钟电路;多功能石英电子钟电路。这些电路是构成石英电子钟机芯的关键器件。不论那一种石英电子钟电路,都是用低功耗CMOS集成电路工艺制作而成。本文只对秒跳 Analog Quartz clock with accurate walking time, power consumption, beautiful and innovative style, easy to use and so on. Mechanical clock has been the pointer quartz electronic wall clock, desk clock, alarm clock, travel clock, etc. instead of the potential. Pointer quartz electronic clock with integrated circuits can be broadly divided into three categories: low-frequency quartz clock circuit; high-frequency quartz clock circuit; multi-function quartz clock circuit. These circuits constitute the key components of quartz clock movement. Regardless of the kind of quartz electronic clock circuit, are made with low-power CMOS integrated circuit technology.
