摘　　要：介绍基于DSP和PLL400的915MHz频段RFID跳频系统设计,探讨DSP对PLL400控制,跳频信道分配、跳频图案设计等问题。实现宽间隔跳频和自适应频率控制,增强了RFID阅读器工作的安全性和稳定性。Design of 915 MHz frequency band adaptive frequency hopping system based on DSP and PLL400 is presented. Control circuit between DSP and PLL400, distribution of the frequency hopping channels, design of frequency hopping patterns are discussed. which enhance security and steadiness Wide gap frequency hopping and adaptive frequency control are achieved, of RFID readers when querying tags.
