Maxay yihiin arrimaha saameeya xasilloonida oscillators crystal quartz?
Crystal oscillators ayaa si weyn loogu isticmaalaa codsiyada la taaban karo, tusaale ahaan, wareegyada saacadaha CPU. Maadaama dhammaan akhristayaasha aysan aqoon u lahayn iyaga, maqaalkani wuxuu soo bandhigayaa xasilloonida soo noqnoqda ee oscillators crystal wuxuuna falanqeynayaa arrimaha saameeya xasilloonida soo noqnoqda ee oscillators crystal quartz.
Degganaanshiyaha soo noqnoqda ayaa qeexaya kala duwanaanshaha soo-saarka oscillator-ka ee uu keeno isbeddelka heerkulka inta lagu jiro hawlgalka. Haddii socodka soo noqnoqda uu ka bato shuruudaha codsiga, khaladaadka wakhtiga ayaa soo bixi doona. Degganaanshaha soo noqnoqda waxa lagu cayimay qaybo halkii milyan (ppm), marka loo eego inta jeer ee magaca ah ee kala duwanaanta heerkulka la cayimay.
Mid ka mid ah astaamaha muhiimka ah ee oscillators crystal quartz waa xasilloonidooda guud ahaan kala duwanaanta heerkulka hawlgalka, tanina waa qodobka ugu weyn ee saameeya qiimaha oscillator-ka crystal. Sida ugu wanaagsan ee xasilloonida soo noqnoqda ama kala duwanaanta heerkulka hawlgalka, ayaa sarreeya kharashka qaybta. Heerka -40~+85 kala duwanaanshaha darajada lagu qeexay heerarka warshadaha waxaa inta badan lagu soo xushay oo kaliya habdhaqanka naqshadeeyayaasha. Haddi heerka -20~{6}} heerkulku buuxiyo shuruudaha, looma baahna in la doorto kala duwanaansho heerkul balaadhan. Injineerada nakhshaduhu waa inay si taxadar leh u qiimeeyaan shuruudaha dhabta ah ee codsigooda ka hor inta aysan cayimin xasilloonida oscillator oscillator-ka. Sifeynta xad dhaafka ah waxay keentaa koror kharash aan loo baahnayn.
Da'da oscillators crystal quartz waa arrin kale oo weyn oo keenta isbeddelka soo noqnoqda. Iyadoo ku xiran shuruudaha nolosha adeegga ee alaabta dhamaadka, habab badan ayaa la heli karaa si loo yareeyo saameyntan. Da'da Crystal waxay sababtaa inta jeer ee wax soo saarka inay raacdo qalooca qulqulka logarithmic, taasoo la macno ah saamaynta gabowga ayaa inta badan loogu dhawaaqaa sanadka ugu horeeya ee shaqada. Tusaale ahaan, heerka gabowga ee crystal ka dib in ka badan 10 sano oo hawlgal ah waa qiyaastii hal -saddex meelood meel heerka sanadka ugu horeeya. Socodkan waxa lagu yarayn karaa farsamooyin farsamayneed oo khaas ah, ama lagu magdhaba habayn. Mid ka mid ah tusaalaha ayaa ah ku dhejinta korantada biinka kantaroolka (sida isku dhafka shaqada xakamaynta korantada).
Waxyaalaha kale ee saameeya xasiloonida waxaa ka mid ah kala duwanaanshaha korantada saadka, isbeddelka culeyska, buuqa wajiga iyo jitter. Halbeegyadan waa in la qeexaa marka la dooranayo oscillators crystal firfircoon. Wixii wershadaha{2}} alaabada darajada, gariir iyo qeexid shoog ayaa mararka qaarkood loo baahan yahay. Qalabka militariga iyo hawada hawada waxay soo rogaan shuruudo dheeraad ah, sida dulqaadka kala duwanaanshaha cadaadiska iyo soo-gaadhista shucaaca.
Quartz crystal oscillators waxaa sida caadiga ah laga soo saaraa crystals quartz synthetic. Quartz synthetic wuxuu taageeraa wax soo saarka ballaaran wuxuuna hoos u dhigaa kharashaadka wax soo saarka, halka kiristaalo quartz ee dabiiciga ah loo isticmaalo oo kaliya qayb yar oo codsiyada ah. Si kastaba ha ahaatee, soo dejinta alaabta crystal ceeriin ayaa kor u kacaysa. Qaar ka mid ah soosaarayaasha oscillator-ka crystal waxay qaataan alaab ceeriin ah oo hooseeya si ay u yareeyaan kharashyada. Isticmaalka alaabtan oo kale waxay u janjeertaa inay keento arrimo ay ka mid yihiin saxnaanta soo noqnoqoshada liidata ee SMD iyo oscillators crystal cylindrical, heerkulka aan ku filnayn, ku guul dareysiga oscillate iyo cilladaha kale ee shaqada.
Margin naqshadeynta guud ahaan waa in la xafidaa inta lagu jiro xulashada qaybaha si loo dammaanad qaado isku halaynta alaabta. Xulashada qaybaha sare - waxay sii yarayn kartaa ixtimaalka guuldarada waxayna keeni kartaa faa'iidooyinka suurtagalka ah. Dhinacan waxa kale oo loo baahan yahay in la tixgeliyo marka la barbar dhigayo qiimaha alaabta. Si loo gaaro waxqabadka guud ee dheellitiran oo macquul ah ee oscillators crystal quartz, injineeradu waa inay miisaamaan arrimo badan oo ay ku jiraan xasilloonida, kala duwanaanta heerkulka hawlgalka, saamaynta gabowga crystal, qaylada wajiga iyo qiimaha. Tixgelinta kharashku kuma koobna oo keliya qiimaha qaybta laakiin sidoo kale kharashka nolosha ee alaabta.
