摘　　要：介绍了一种锁相频率合成器 BU2 615 ,结合专用收音模块 CXA10 19S、单片机 AT89C5 1能实现 FM调谐器 ,该调谐器能实现频率扫描、锁定和显示等功能。使用串行 E2 ROM存储必要数据 ,实现数据掉电保护功能 。This paper introduces a PLL frequency synthesizer BU2614 combined with a special radio module CAX1019S and a MCU AT89C51, which can realize the FM tuner. The tuner can realize multiple functions, such as automatic frequency scanning, locking, and displaying etc. In order to protect data loss on power fault, a serial E 2ROM24L16 is applied to store the data of radio stations. Parts of real circuits and main program flow diagram are provided in detail.

关 键 词：锁相频率合成器 BU2614 FM调谐器 频率扫描
