Crystal oscillator ke senotlolo sa potoloho ea dijithale, mosebetsi oa Crystal o sebelisoa ka kotloloho letšoao la potoloho, le se ke hore haeba ho na le moralo oa potoloho oa dijithale ho ka bona oscillator ea potoloho ea dijithale.
I. Oscillator ke eng?
Crystal Oscillator ka kakaretso e bua ka mefuta e 'meli ea li-oscillator tse peli tsa Quartz le Quartz Rescillator ea Crystal. Ka bobeli ba entsoe ka phello ea piezoelectric ea li-kristale tsa Quartre.
Crystal oscillator e boetse e sebetsa tjena: Ha tšimo ea motlakase e tla sebelisoa ho matla a kristale, kristale e tla hlahisa tšimo ea kristale, kristale e tla hlahisa tšimo ea motlakase. Pheno ena e fetotsoe, ka hona e sebelisa tšobotsi ena ea kristale, ho eketsa likarolo tse fapaneng ho lipheletso tsa kristale, 'me ka nako e ngata li hlahisa masimo a motlakase a amanang le ona. Leha ho le joalo, ho vibration ena le lebala la motlakase tse hlahisitsoeng ke kristale hangata ho nyane, mokhoa oa LC o tla hopola hore hangata baqapi ba potoloho hangata ba bona. Khafetsa re bona hangata.
II. Classification of Crystal Oscillation (E mafolofolo le e Pate)
① Passive Crystal Oscillator
Crystal e ikhethileng ke kristale, ka kakaretso sesebelisoa sa 2 se seng sa polar (kristale e 'ngoe ea pente e na le phini e tsitsitseng e se nang thuso).
Passive oscillator ea Crystal o hloka ho itšetleha ka oache ho potoloha ke Cape Pitacitor ho hlahisa letšoao la signal (sine Wave Signal).
② Oscillator e sebetsang ea Crystal
Crystal oscillator o sebetsang ke oscillator, hangata e nang le 4. Oscillator e sebetsang e sebetsang ha e hloke oscillator ea ka hare ea CPU ho hlahisa letšoao la lisekoere-wave. Phepelo ea motlakase o sebetsang o hlahisa lets'oao la liaparo.
Letšoao la Oscillator e sebetsang e sebetsang e tsitsitse, boleng bo betere, 'me phoso e ka sehloohong e theko e tlaase ho feta kristale e iphetetsang.
III. Liparame tsa mantlha tsa Crystal Oscillator
Litšitiso tsa mantlha tsa li-kristale tse akaretsang tsa kristale li: mocheso o sebetsang, boleng ba ho tsepamisa mohopolo, foromo ea pakete, maqhubu a moeli, hangata a le joalo.
Khafetsa Crystal Oscillator: Khetho ea crystal crystal e latela litlhoko tsa litsie tsa khafetsa, tseo ka kakaretso li tsoang ho 4M ho feta ho ba le li-m.
Ka kakaretso ho nepahala ho khabisitsoeng: Ho nepahala ha ho hlophisoa ha kristale hangata ho joalo ka li-chips, ± 50ppm, ± 50ppm, u tla khetha ka ± 20ppm.
Boima ba papali ea kristale oscillator: Hangata ka ho fetola boleng ba bokhoni ba cristal, 'me hajoale o sebelisoa ho fetola Oscillator ea Crystal e phahameng.
Ts'ebetsong ea potoloho, mohala o phahameng oa mokokotlo o na le ntho e tlang pele ka ho fetisisa. Lethathamo la Clock ke sepontšo se tebileng, le khafetsa, mosomi o hlokahala ho netefatsa hore ho hlomoha hoa letšoao ke ho fokolang.
Hona joale lipotoloho tse ngata, hangata matla a ho kena-kenana le a radiation a tlamehang mahlaka, empa a kile a baka mekhoa e meng e potlakileng ea ho rarolla mekhoa e meng. Ka hona, ho bohlokoa haholo bakeng sa kristal oscillator le clk mochine oa lets'oao la "clk"
