ASM3P2879A芯片是一种用于减少电磁干扰(EMI)的展频频率调制器。它的EMI优化技术主要通过以下几个方面实现:
展频时钟信号生成:ASM3P2879A能够生成一个经过EMI优化的时钟信号,通过在时钟信号的频谱中引入一定的频率偏移,从而降低频谱中的峰值幅度。
集成环路滤波器组件:该芯片内部集成了环路滤波器组件,这有助于进一步优化时钟信号的稳定性和减少噪声。
低功耗CMOS设计:采用低功耗CMOS技术设计,有助于降低整体系统的能耗,同时保持高性能。
工作电压范围:芯片可以工作在3.3V或2.5V的供电电压下,这为不同应用场景提供了灵活性。
输入频率范围:芯片的输入频率范围是13MHz到30MHz,这允许它适配多种不同的时钟频率。
调制率和频率偏差:ASM3P2879A使用FCC批准的最有效和优化的调制轮廓,通过数字方法实现,调制率由公式FIN/640\text{FIN}/640决定,频率偏差控制在±1% @ 24MHz,这有助于进一步降低EMI。
单PLL调制:该芯片调制单个PLL的输出,以“扩展”合成时钟的带宽,更重要的是降低其谐波的峰值幅度,从而显著降低系统的EMI。
展频时钟生成:通过增加信号的带宽来降低EMI,这种方法称为“展频时钟生成”。
应用范围:ASM3P2879A主要针对所有具有极低功耗要求的便携设备,如MP3播放器、笔记本电脑和数字相机。
通过上述技术,ASM3P2879A芯片能够有效地减少时钟源的电磁干扰,允许系统在减少电路板层数、减少铁珠和屏蔽等传统EMI合规措施的同时,实现更低的系统EMI。
