时钟电路5G5544H 为 CMOS 集成电路,双列直插8脚封装,是上海元件五厂新研制的专用时钟电路。电路的性能指标及封装与 SM5544H 一致,可以互换。时钟电路5G5544H 专为闹钟设计,所以适用于一节电池工作,且只需外接32.768KHz 石英晶体和频率微调电容,就可自激工作并精确调整走时精度。电路的输出可直接驱动时钟的步进电机。图1和表1分别列出有关的电路图和主要参数。 Clock circuit 5G5544H for CMOS integrated circuits, dual in-line 8-pin package, is the fifth element of the Shanghai Institute of Newly developed dedicated clock circuit. Circuit performance and package specifications and SM5544H consistent, interchangeable. Clock circuit 5G5544H designed for alarm clock, so suitable for a battery work, and only an external 32.768KHz quartz crystal and frequency trimmer capacitor, you can self-excited work and accurately adjust the travel time accuracy. The output of the circuit can directly drive the stepper motor of the clock. Figure 1 and Table 1 list the relevant circuit diagram and the main parameters.
