I-Oven Controlled Crystal Oscillator (OCXO)

I-Oven Controlled Crystal Oscillator (OCXO) iyi-crystal oscillator esebenzisa ithangi lokushisa elihlala njalo ukugcina izinga lokushisa le-quartz crystal resonator ku-crystal oscillator njalo, futhi ukuguqulwa kwe-oscillator okukhipha imvamisa okubangelwa ukuguquka kwezinga lokushisa elizungezile kuyancishiswa kube okungenani. I-OCXO yakhiwe yisekethe yokulawula izinga lokushisa engaguquki kanye nesekethe ye-oscillator, imvamisa isebenzisa "ibhuloho" le-thermistor elakhiwe i-amplifier yochungechunge oluhlukile ukuze kuzuzwe ukulawula izinga lokushisa.

Inezici ezilandelayo:

1. Ukusebenza kwesinxephezelo sezinga lokushisa okuqinile: I-OCXO ifinyelela isinxephezelo sezinga lokushisa ku-oscillator ngokusebenzisa izakhi zokuzwa izinga lokushisa kanye neziyingi zokuzinzisa. Iyakwazi ukugcina ukuphuma kwefrikhwensi kuzinzile kumazinga okushisa ahlukene.
2. Ukuzinza kwefrikhwensi ephezulu: I-OCXO imvamisa inokuqina okunembe kakhulu, ukuchezuka kwayo kuncane futhi kuzinzile. Lokhu kwenza ukuzinza okuphezulu kwe-OCXO kulungele izinhlelo zokusebenza ezinezidingo zefrikhwensi ephezulu.
3. Isikhathi sokuqalisa esisheshayo: Isikhathi sokuqalisa se-OCXO sifushane, ngokuvamile ama-millisecond ambalwa kuphela, angamisa ngokushesha ukuvama kokuphumayo.
4. Ukusetshenziswa kwamandla okuphansi: Ama-OCXO ngokuvamile asebenzisa amandla amancane futhi afanele izinhlelo zokusebenza ezinezidingo zamandla eziqine kakhulu, ezingalondoloza amandla ebhethri.

Izicelo ze-Oven Controlled Crystal Oscillators:

1. Izinhlelo zokuxhumana: I-OCXO isetshenziswa kakhulu kwezokuxhumana ngeselula, ukuxhumana ngesathelayithi, ukudluliswa kwedatha okungenantambo kanye neminye imikhakha ukuze kuhlinzekwe imvamisa yereferensi ezinzile.
2. Amasistimu wokuma nawokuzulazula: Kuzinhlelo zokusebenza ezifana ne-GPS ne-Beidou navigation System, i-OCXO isetshenziselwa ukunikeza amasignali ewashi anembile, okuvumela uhlelo ukubala ngokunembile indawo kanye nesikhathi sokulinganisa.
3. Amathuluzi: Emishinini yokulinganisa ngokunemba namathuluzi, i-OCXO isetshenziselwa ukunikeza amasignali ewashi anembile ukuze kuqinisekiswe ukunemba nokukhiqizwa kabusha kwemiphumela yokulinganisa.
4. Imishini ye-elekthronikhi: I-OCXO isetshenziswa kakhulu kumjikelezo wewashi wezinto zikagesi ukuze kuhlinzekwe imvamisa yewashi ezinzile ukuze kusebenze ukusebenza okuvamile kwedivayisi.

Ngamafuphi, i-OCXO inezici zokusebenza kwesinxephezelo esiqinile sokushisa, ukuzinza okuphezulu kwemvamisa, isikhathi sokuqalisa ngokushesha kanye nokusetshenziswa kwamandla okuphansi, okulungele izinhlelo zokusebenza ezinezidingo zemvamisa ephezulu futhi ezizwelayo ekushintsheni kwendawo yezinga lokushisa.
