YXC无源晶振【选型篇】
晶振是一种能够产生时钟频率信号的关键元件。无源晶振的工作原理基于石英的压电效应。在石英水晶片的两边镀上电极,当在两电极上加一定的电压时,由于石英的压电效应会产生形变,从而给IC提供一个正弦波形。这个正弦波形经过IC的内部整形和PLL(锁相环)电路后,产生方波,然后输入给下级电路。无源晶振必须结合外围电路构成一个振荡器才能输出特定频率的信号,而这个振荡器需要外部电源提供驱动电流。

解析无源晶振的工作原理
无源晶振的工作原理是基于压电效应和共振原理原理交互作用而产生的。晶体通过加电场产生压电效应,发生压缩或扭曲变形引起足够振荡能量时实现回振,电路通过外接电路(电容、电感)实现振荡自激效应。由此,产生了稳定、准确的频率信号。无源晶振作为一种高精度的时基电子元件,其广泛地应用于计算机、通信以及其他电子设备中,并发挥着重要的作用。
用于音频应用的时钟芯片SJWCH5351,支持I²C接口编程,实现单一芯片取代锁相环、晶振、压控振荡器
SJWCH5351产生多路自由运行时钟以用于替换晶体和晶体振荡器的内部振荡器,方便实现输出智能音频系统所需的48kHz采样时钟、对应3.072MHz的位同步时钟以及90.3168MHz的系统时钟,只需外面挂一颗25MHz的价格较低的无源晶体作为输入源,可正常实现三路不同频点输出。
