摘要
介绍了TEF6606芯片在车载收音机中的应用,根据车载供电的特点设计电路,实现了省电模式下低功耗操作;利用I^2C总线通信,控制TEF6606芯片相应的寄存器实现数字调频立体声收音功能的方法,并通过软件编程实现自动搜台、浏览选听等收音功能的多样化,满足不同的收音要求。
This paper mainly introduces the application of TEF6606 chip in car radio. According to the characteristics of automotive power supply, a reasonable circuit is designed, so the lower power consumption can be achieved in power-saving mode. The MCU control the corresponding registers of TEF6606 chip by the I^2C bus to implement the digital tuned stereo radio. And in order to meet the different requirements, the diversification of tuning function , such as audio-search and scampering modes, can be realized by programming.
