I-Crystal Oscillator iyisihluthulelo kumklamo wesifunda sedijithali, imvamisa ekwakhiweni kwesifunda, wonke umsebenzi wesifunda sedijithali uhlukaniswa ngokuqondile ukuqala kwesikole sonke, kungashiwo ukuthi uma kukhona umklamo wesifunda wedijithali angabona i-Crystal Oscillator.

I. Yini i-crystal oscillator?

I-Crystal Oscillator ngokuvamile isho izinhlobo ezimbili ze-quartz crystal oscillator kanye ne-quartz crystal resonator, futhi ingabizwa ngqo ngqo i-Oscillator. Zombili zenziwa zisebenzisa umphumela we-piezoelectric wamakristalu e-quartz.

I-Crystal Oscillator isebenza kanjena: Lapho insimu kagesi isetshenziswa kuma-elektrokhi amabili wekristalu, ikristalu izobhekana nokuguquguquka kwemishini, naphezu, uma ingcindezi yemishini isetshenziswa emaphethelweni amabili ekristalu, ikristalu lizoveza insimu kagesi. Lesi simo siyaguqulwa, ngakho-ke sisebenzisa lesi sici sekristalu, ukungeza ukushintshashintsha kwamandla ama-voltages kuwo womabili ama-crystal, i-chip izokhiqiza ukudlidliza kwemishini, futhi ngasikhathi sinye kukhiqiza izindlela zikagesi ezishintshashintshayo. Kodwa-ke, le nkambu ye-vibrate ne-gener eyenziwe yi-crystal ngokuvamile incane, kepha inqobo nje uma isemhlabeni othile, okuphezulu kuzokhuphuka kakhulu, okufana kakhulu ne-LC Loop Designers esivame ukubonana.

II. Ukuhlukaniswa kwama-Oscals we-Crystal Oscillations (asebenzayo futhi angenasisekelo)

① I-Passip Crystal Oscillator

I-Passive Crystal iyi-crystal, ngokuvamile idivaysi engu-2-PIN okungeyona i-polar (I-Pines Crystal ene-PIN ebekiwe engenabukhosi).

I-Passip Crystal Oscillator ngokuvamile idinga ukuncika kumjikelezo wewashi owakhiwa yi-facacitor yokulayisha ukukhiqiza isinali ye-Oscillating (Sine Wave Signal).

② I-Crystal Oscillator esebenzayo

I-crystal oscillator esebenzayo yi-oscillator, imvamisa enamakhonkwane ayi-4. I-Crystal Oscillator esebenzayo ayidingi i-Oscillator yangaphakathi ye-CPU ukukhiqiza isinali yegagasi lesikwele. I-Crystal Power Power esebenzayo ikhiqiza isinali yewashi.

Isiginali ye-Crystal Oscillator esebenzayo iyazinza, ikhwalithi ingcono, futhi imodi yokuxhumana ilula, iphutha lentengo lincane kunaleso se-Prep Crystal Oscillator, futhi intengo ibiza kakhulu kune-Crystal Oscillator.

III. Amapharamitha ayisisekelo weCrystal Oscillator

Amapharamitha ayisisekelo we-General Crystal Oscillator yilezi: izinga lokushisa elisebenzayo, inani lokunemba, ukukhohlisa, ifomu lephakheji, imvamisa yephakheji, imvamisa yephakheji nokunye.

The core frequency of the crystal oscillator: The choice of the general crystal frequency depends on the requirements of the frequency components, like the MCU is generally a range, most of which are from 4M to dozens of M.

Ukunemba kwe-Crystal Vibration: Ukunemba kokudlidliza kwekristalu ngokuvamile

Ukuhambisana okufanayo kwe-Crystal Oscillator: Ngokuvamile ngokushintsha inani lokulinganisa okufanayo, imvamisa ye-crystal oscillator ingashintshwa, futhi njengamanje, le ndlela isetshenziselwa ukulungisa i-Crystal Oscillator ephakeme ephezulu.

Ohlelweni lokujikeleza, umugqa wesiginali we-Clock Clow Clock Clock unezinto eziphambili kakhulu. Umugqa wewashi uyisiginali ebucayi, futhi ukhuphuka imvamisa, umugqa mfushane ulayini uyadingeka ukuqinisekisa ukuthi ukuhlanekezela kwesiginali kuncane.

Manje emibuthanweni eminingi, imvamisa yewashi le-crystal yesistimu iphezulu kakhulu, ngakho-ke amandla okuphazamisa ama-harmonics nawo aqinile, futhi futhi aholele ekutheni kube yinkinga ye-PCStal Oscillator, futhi okunzima ukuxazulula ezinye izindlela. Ngakho-ke, kubaluleke kakhulu kwi-Crystal Oscillator kanye nokwakheka komugqa we-CLK Signal Signal lapho iBhodi lePCB liyabekwa.
