Ubuchwephesha obuphambili bokuPhumelela iUltra{0}}Inqanaba eliphantsi leNgxolo kwii-OCXOs

I-oveni {{0}Ii-Crystal Oscillators eziLawulwayo (i-OCXOs) ibambe indawo engenakuphinda ithathelwe indawo kwibala lexesha elichanekileyo, kwaye ukusebenza kwazo okugqwesileyo kubangelwa kulawulo olucwangcisiweyo lwengxolo yesigaba. Ukufezekisa le njongo, ukulungelelaniswa okupheleleyo ukusuka ekukhethweni kwezinto kunye noyilo lwesekethe kulawulo lokusingqongileyo kuyadingeka. Apha ngezantsi kukho imikhombandlela emithandathu engundoqo yokuqonda ingxolo enkulu-yenqanaba elisezantsi.

Izinto ezingundoqo zobuGcisa

1. Ulawulo lobushushu obuchanekileyo

Ngokusebenzisa -isakhiwo se-oveni ephindwe kabini, iqondo lobushushu lekristale lizinzisiwe kwindawo yalo yokuguquguquka kobushushu (ngokuqhelekileyo i-75-85 degree), inciphisa impembelelo yokuguquguquka kobushushu ukuya ngaphantsi kwe-1/100 yenqanaba lokuqala. Le ndlela yokulawula ubushushu ithintela ngokufanelekileyo indlela yokuvelisa yengxolo yesigaba esibangelwa ngubushushu.

2. Ukuphuculwa kwezinto zeCrystal

Uxinzelelo -lwehlisiwe i-SC{1}}iikristale ezisikiweyo zamkelwa endaweni ye-AT{2}}iikristale ezisikiweyo, ezidityaniswe neteknoloji ye-ion etching, inyusa i-intrinsic Q factor yekristale ngaphezulu kwe-30%. Olu phuculo lunciphisa ngokuthe ngqo umgangatho we-1/f wengxolo nge-6-8 dB.

3. Ukwenziwa kwezinto ezintsha kwiSakhiwo seSekethe

Usebenzisa-isiseko sesekethe ye-oscillation topology, edityaniswa{1}}nezixhobo eziphantsi ze-JFET zengxolo, icinezela ngokufanelekileyo igalelo lengxolo yombane ukuya ngaphantsi -170 dBc/Hz. Uyilo olwahlukileyo olulinganayo luthintela ngakumbi ukuqaliswa kwengxolo yemowudi eqhelekileyo.

4. UYilo loLwakhiwo oluchubekileyo loomatshini

Inkqubo yokubeka yodwa ye-multi-yenqanaba lokungcangcazela, idityaniswe nesakhiwo sezindlu esiphuculwe ngokuhlalutywa kwezinto ezinomda, inciphisa ubuntununtunu be-OCXO kwiintshukumo zangaphandle zoomatshini ngama-20 dB. Olu luyilo lufanelene ngakumbi-nendawo ezishukumayo eziphezulu ezifana ne-aerospace kunye ne-automotive applications.

5. Ukucocwa kweNkqubo yokuBonelwa koMbane

Ulwakhiwo oludityanisiweyo -lwenqanaba lolwakhiwo lombane lolawulo{1}}olubandakanya{2}}ngaphambili, ummiselo womda, kunye nohluzo olusebenzayo{3}}luphucula iRatiyo yokuLalwa koMbane (PSRR) ukuya kuma-80 dB. Ngeli xesha, iteknoloji yembuyekezo yenguquko ye-AM{{6} ephuhliswe ngokuzimeleyo isetyenziselwe ukucinezela ngokufanelekileyo ukuphazamiseka kwesigaba okubangelwa kukuguquguquka konikezelo lwamandla.

6. UPhulo lweMiqondiso

Ibhendi ehlengahlengiswayo -yokumisa isihluzi sidityaniswe kwinqanaba lemveliso, ibonelela ngaphezulu kwe-40 dB yokucinezela kwi-2nd kunye neye-3 ye-harmonics. I-adaptive impedance ehambelana nenethiwekhi iqinisekisa ukucoceka komqondiso wemveliso phezu komgangatho wokushisa osebenzayo.

Izalathisi zoMsebenzi oPhambili

Kwizicelo ezisebenzayo, iimveliso ze-OCXO zamkela obu buchwepheshe bunokufezekisa:

-140 dBc/Hz @ 100 Hz

-160 dBc/Hz @ 1 kHz

-180 dBc/Hz @ 10 kHz

Iimeko zosetyenziso oluqhelekileyo

Ezi nkqubela phambili zetekhnoloji zenza ukuba ii-OCXO zidlale indima ephambili kwezi nkalo zilandelayo:

I-Millimeter{0}}isigaba samaza ungqamaniso kwizikhululo ezisisiseko ze-5G/6G

Ukuveliswa komqondiso kwiirada zokuvula zokwenziwa

Ukuchaneka ukusuka kwiprobe yendawo enzulu

Ukuhanjiswa kwewotshi kwiinkqubo ze-quantum computing

Iindlela zoPhuhliso lweTekhnoloji

Itekhnoloji yangoku ye-OCXO iguqukela ekudityaneni okuphezulu kunye nokusetyenziswa kwamandla aphantsi. Izisombululo ezitsha ezifana ne-MEMS{1}i-oveni ezincinci ezisekwe kunye nesilicon{2}}esekwe kwikristale resonators ziyaphula imida yokusebenza kwee-OCXO zemveli. Ubukrelekrele bokwenziwa{4}}obuncedisiweyo bokulawula ubushushu buqalisile ukusetyenziswa kwisizukulwana esitsha seemveliso, okwenza ukuba ukulandelwa kobushushu obuchane ngakumbi kunye namaxesha okuqalisa ngokukhawuleza{5}}.

Ngokusebenzisa i-synergistic optimization yetekhnoloji ekhankanywe ngasentla, ii-OCXOs zanamhlanje zinokuzisa ukusebenza kwesigaba sengxolo kufutshane nomda wethiyori phantsi kweemeko ezirhabaxa zendalo esingqongileyo, zibonelela ngereferensi ethembekileyo yokwenziwa rhoqo kokusika{0}}usetyenziso lwetekhnoloji.
