技术问答

破壁机不管是家用还是商用都在厨房家电中占有一席之地，商用破壁机是奶茶店、饮料店的好帮手。商用破壁机相比于家用破壁机功能更多，对性能要求也更严苛。

客户在设计一款商用破壁机时，因MCU内置的时钟精度不能满足需求，需要外置一颗8M的无源晶振，精度要求10PPM，贴片封装，体积小一点。笔者推荐了国产晶光华的HC-49S系列的无源晶振，8M的具体型号是49SAT080000201060，精度10PPM，满足客户需求。下图是产品应用框图。

选择49SAT080000201060的理由：

1、匹配电容20PF，精度在10PPM，精度高，满足客户需求。

2、贴片封装，尺寸11.4x4.8x3.8mm，体积小，节省电路板面积。

3、国产厂牌，供货有保障，物美价廉。
