ASM3P2879A是一款用于降低电磁干扰(EMI)的展频频率调制器,适用于需要低功耗的便携设备,如MP3播放器、笔记本电脑和数字相机。该芯片通过展频技术减少时钟源的电磁干扰,从而降低整个系统的EMI水平。
在文件中,有一个典型应用电路图,可以作为设计参考。以下是该芯片典型应用电路的一些关键组件和设计要点:
晶振振荡器电路:ASM3P2879A通常与晶振一起使用,以提供稳定的输入频率。晶振的规格也在文档中给出,例如14.31818MHz的标称频率,频率公差为±50ppm或更好。
电源:芯片可以工作在2.5V或3.3V的供电电压下。
输入/输出引脚:芯片具有不同的引脚配置,例如6引脚TSOT-23封装或8引脚SOIC和TSSOP封装。文档中提供了不同封装的引脚配置图。
调制配置:ASM3P2879A通过单一PLL(相位锁定环)输出调制,以“扩展”合成时钟的带宽,并降低其谐波的峰值幅度。
典型电路:文档中的典型应用电路图展示了如何将ASM3P2879A与外部元件(如晶振、去耦电容等)连接。
去耦电容:在电源引脚VDD和地引脚VSS之间通常需要放置去耦电容,以减少电源噪声。
负载电容:晶振两端可能需要连接负载电容,以确保晶振在规定的频率下稳定振荡。
输出:芯片提供了调制后的时钟输出ModOUT,可以连接到需要时钟信号的设备。
参考输出:REFOUT引脚提供了输入频率的缓冲输出,如果设计中需要的话。
无连接引脚:某些封装类型中可能包含NC(无连接)引脚,这些引脚在电路设计中不需要连接。
请注意,具体的电路设计还需要考虑实际应用中的其他因素,如电源管理、信号完整性、PCB布局和布线等。如果你需要更详细的电路设计示例或指导,可以进一步研究该芯片的数据手册或联系芯片制造商获取技术支持。
