摘　　要：主要介绍了在个人数字助理(PDA)系统开发平台中,利用PHILIPS公司的FM收音机单芯片TEA5768HL通过I2C总线进行通信来设计和实现数字调频立体声收音机模块。重点讲述了TEA5768HL的工作原理、收音机模块设计方案。此收音机模块具有高性能、低功耗、低成本、占PCB面积小、CPU控制方便等优点,同时它也适合应用于智能手机、MP3播放器等掌上嵌入式系统产品中。In this paper, a digital tuned radio module is designed and implemented by the single chip FM radio IC TEA5768HL of PHILIPS and I^2C bus in the PDA developing platform. It describes I^2C bus technology and the circuit principle of TEA5767HN adn discusses the H/W design of the radio module. The testing result of the performance is listed in the end. This solution has proved to be of high performance, low power dissipation, low cost, reduction in PCB space and to be conveniently controlled by CPU. It is fit for the handheld system embedded application, such as smartphone and MP3 player.
