A Design of Real-Time Clock for Wireless Communication SoC in Smart Grid

Yingying Chi, Zhe Zheng


This paper presents a real-time clock (RTC) designed for wireless communication system-on-chip (SoC) in smart grid. The RTC is a high-density integrated application-specific circuit using high-precision crystal oscillator as the clock source to keep track of time and date information. The accuracy of travel time makes it very suitable for all occasions requiring low power consumption and accurate timing. The front-end design is implemented with Verilog HDL, and the back-end design and verification are performed with Synopsys` EDA tools.
