I-Oven Controlled Crystal Oscillator (OCXO)

I-Oven Controlled Crystal Oscillator (OCXO) iyi-crystal oscillator esebenzisa ithangi lokushisa elingaguquki ukugcina izinga lokushisa le-quartz crystal resonator ku-crystal oscillator constant, futhi ushintsho lwemvamisa yokukhishwa kwe-oscillator olubangelwa ushintsho lokushisa oluzungezile luyancipha lube luncane. I-OCXO yakhiwe yisekethe yokulawula ithangi lokushisa elingaguquki kanye nesekethe ye-oscillator, ngokuvamile isebenzisa "ibhuloho" le-thermistor elakhiwe nge-differential series amplifier ukuze kufezwe ukulawula izinga lokushisa.

Inezici ezilandelayo:

1. Ukusebenza kahle kokunciphisa izinga lokushisa: I-OCXO ithola isinxephezelo sokushisa ku-oscillator ngokusebenzisa izakhi zokuzwa izinga lokushisa kanye namasekethe okuzinzisa. Iyakwazi ukugcina umphumela ozinzile wemvamisa emazingeni okushisa ahlukene.
2. Ukuqina kwemvamisa ephezulu: I-OCXO ivame ukuba nokuqina kwemvamisa okunembile kakhulu, ukuphambuka kwayo kwemvamisa kuncane futhi kuzinzile. Lokhu kwenza ukuqina kwemvamisa ephezulu i-OCXO ifanele izinhlelo zokusebenza ezinezidingo zemvamisa ephezulu.
3. Isikhathi sokuqalisa esisheshayo: Isikhathi sokuqalisa se-OCXO sifushane, ngokuvamile ama-millisecond ambalwa kuphela, okungazinzisa ngokushesha imvamisa yokukhipha.
4. Ukusetshenziswa kwamandla aphansi: Ama-OCXO ngokuvamile asebenzisa amandla amancane futhi afanele izinhlelo zokusebenza ezinezidingo zamandla eziqinile, ezingonga amandla ebhethri.

Ukusetshenziswa kwama-Oscillator e-Crystal alawulwa yi-Oven:

1. Izinhlelo zokuxhumana: I-OCXO isetshenziswa kabanzi ekuxhumaneni ngeselula, ekuxhumaneni ngesathelayithi, ekudlulisweni kwedatha engenantambo nakwezinye izinkambu ukuze inikeze imvamisa yokubhekisela eqinile.
2. Izinhlelo zokubeka kanye nokuzulazula: Ezinhlelweni zokusebenza ezifana ne-GPS kanye ne-Beidou navigation System, i-OCXO isetshenziselwa ukunikeza izimpawu zewashi ezinembile, okwenza uhlelo lukwazi ukubala indawo ngokunembile kanye nokukala isikhathi.
3. Ukwenziwa Kwezinsimbi: Emishinini namathuluzi okulinganisa ngokunembile, i-OCXO isetshenziselwa ukunikeza izimpawu zewashi ezinembile ukuqinisekisa ukunemba nokuphindaphindwa kwemiphumela yokulinganisa.
4. Imishini ye-elekthronikhi: I-OCXO isetshenziswa kabanzi kumjikelezo wewashi wemishini ye-elekthronikhi ukuze inikeze imvamisa yewashi ezinzile ukuze kusebenze ukusebenza okuvamile kwedivayisi.

Ngamafuphi, i-OCXO inezici zokusebenza okunamandla kokunciphisa izinga lokushisa, ukuzinza kwemvamisa ephezulu, isikhathi sokuqalisa esisheshayo kanye nokusetshenziswa kwamandla aphansi, okulungele izinhlelo zokusebenza ezinezidingo zemvamisa ephezulu futhi ezizwela izinguquko zemvelo yezinga lokushisa.
