实时时钟电路设计

Real-Time Clock Circuit Design

实时时钟 (RTC)作为系统同步或时间标志已被广泛应用于各种电子产品 ,利用DallasSemicon ductor提供的多种类型的RTC芯片 ,用户在设计中可方便地针对具体应用来选择相应的芯片。文中讨论了一些与实时时钟晶振选择以及电路设计相关的问题。

Dallas Semiconductor offers a large number of Real-Time Clock choices,allows the end user to deˉsign with the clock needed for their application.The crystal selection and layout techniques for real-time clock(RTC)circuit is described in this paper.And the questions about oscillator circuit-design criteria and system design are provided as well.
