介绍了锁相环的原理和ADF4193芯片的特点和配置方式,结合Altera的SOPC技术,利用SOPC Builder中集成的SPI核,设计了一种基于Nios II软核CPU的嵌入式系统,用来配置AD公司生产的快锁芯片ADF4193。实测结果表明,配置成功。并且经过适当修改可用于其他基于SPI串口配置的芯片。
This paper introduces the principle of PLL and the features and configuration of ADF4193 chip. Based on the SOPC technology of Altera and the SPI core integrated in SOPC Builder, an embedded system based on Nios II soft core CPU is designed to configure AD Produced by the fast chip ADF4193. The measured results show that the configuration is successful. And can be used for other chips based on SPI serial port configuration with proper modifications.
