• 稀缺性的無源晶振使得ECS晶振格外有優(yōu)勢?ECS-120-20-5PXDN-TR，There are many other results of shrinking crystals. It’s not just a simple change to the process or build. Shrinking crystals are a major transformation to the design of the oscillator. In any frequency-related circuit, this will have further repercussions. Timing solutions are complex, so it’s important to recognize that functional changes can occur when modifying design. Things to watch include:
• Reduced Motional Capacitance (C1) - Also proportional to the electrode area at certain frequencies.
• Trim Sensitivity (TS) - When the circuit is not adjusted, the smaller load capacitance reduces TS.
• Perturbations - Deviations from ideal frequency resulting from different crystal cuts.

While there is not as much definitive information on these factors, they have been proven enough to be affected by smaller crystals to be monitored.

稀缺性的無源晶振使得ECS晶振格外有優(yōu)勢?ECS-120-20-5PXDN-TR，晶體收縮還有許多其他的結(jié)果。這不僅僅是對(duì)流程或構(gòu)建的簡單更改。貼片晶振的收縮是振蕩器設(shè)計(jì)的一個(gè)重大轉(zhuǎn)變。在任何與頻率相關(guān)的電路中，這將產(chǎn)生進(jìn)一步的影響。時(shí)間的解決方案是復(fù)雜的，所以在修改設(shè)計(jì)時(shí)認(rèn)識(shí)到功能更改是很重要的。ECS晶振需要注意的事項(xiàng)包括:

減小C0 -當(dāng)尺寸縮小到適合更小的封裝時(shí)，電極也更小。C0與電極成正比，所以它也會(huì)縮小。
減小運(yùn)動(dòng)電容(C1) -也與特定頻率下的電極面積成正比。
