基于MC13233的ZigBee物理层分析与设计

摘要

以Freesacle公司的ZigBee RF4CE芯片MC13233为基础,依据嵌入式硬件构件的规范设计了硬件各模块.介绍MC13233的ZigBee物理层的模型.详细阐述MC13233的ZigBee物理层的设计方法,具体实现RF收发器的工作模式设置、物理层数据收发、CCA/ED/LQI,并给出了物理层正确性和可靠性测试.%Based on microcontroller MC13233 which is produced by Freescale Corporation for ZigBee RF4CE,the paper designs all MC13233 hardware modules based on the Embedded Building Blocks specifications. It introduces the ZigBee physical layer model of MC13233 and elaborates its design method, and concretely realizes the RF transceiver mode settings, the physical layer data transceiver as well as CCA/ED/LQI,and at last offers a test for physical layer validity and reliability.
