Liggéey bi ñuy jëfandikoo: Laal sampling, feeñal, lees audio, ak ñoom seen, ñoom ñépp dañu soxla seeni royuwaayi montor ngir mëna déggoo liggéey bi.

3. Miniaturisation ak boole:

Osilatëri kristal yuñ monte ci kaw suuf (SMD) yu melni 3225, 2520, 2016, 1612, ak xeetu SMD ñooy gëna bari, ngir mëna dëppoo ak bëgg-bëggu bayaalu PCB bu dëgër lool ci aparey elektronik yu bees yi.

4. Dakkal ak wóor:

Aparey elektronik yi dañu wara mëna dox bu baax ci anam yu bari (coppite tàngoor, yëngu yu woyof). Osilatëru kristal yi dañu wara am màndarga tàngoor yu baax ci fréquence (indicatëru stabilite), baña yëngu ak yëngu, ak wóor ci diir bu yàgg.

5. Xool ni ñuy mànkee kuuraŋ:

Rawatina sa oscillateur kristal RTC, seen konsommasioŋ bu tuuti lool ci kuuraŋ lu am solo la ngir yokk diiru xaarandi aparey bi. Konsommaasioŋu doole bu yeneen osilatëri kristal itam dafa wara nekk ci diggante buñ mëna saytu.

6. Njëgg-Njariñ:

Ci premise ngir mëna dëppoo ak li ñuy laaj ci performance, tànn oscillateur kristal ak performance bu gëna baax lu am solo la ci defarkat yi. Amna ay wuute yu am solo ci njëg yi ci digganté oscillateurs kristal yu bari ay paquet, niveau de précision ak màrk.

Conclusion: e-bookcase senaario aplikaasioŋ la bu am ay laaj yu bari te bari ci osilatëri kristal yi. Xam anam wi sistem bi di doxee ak li modle bu nekk di sàkku ci osilatëru kristal (paquet, fréquence, capacité de charge, indicateurs de performance core) mooy li am solo. Focus ci ñaari - valeur bu kawe ak - poñ yi ñuy laaj ci montor yu mag yi ak montor yi amul kable, joxe produit yu méngoo bu baax, performance bu wóor, ak taxawaayu joŋante, boole ci ndimmbalu xarala yu xarañ, dina jàppale Hangjing ubbi marse bi bu baax. Fexeel bu baax ci miniaturisation (2520, 1612) ak njubte bu rëy, dayo bu rëy dina nekk tendaas ci jëfandikoo osilatëri kristal!
