Izinzuzo ze-Low Phase Noise VCXO Oscillator 7 X 5

Umsindo Wesigaba Esiphansi Kakhulu
Isigaba somsindo isilinganiso se-jitter yesigaba sesignali yefrikhwensi, ikalwa nge-dBc/Hz (amandla omsindo ngomkhawulokudonsa we-Hz ngamunye uma kuqhathaniswa namandla enkampani yenethiwekhi). Umsindo wesigaba esiphansi usho i-spectrum yesignali ehlanzekile, ukuphazamiseka okuncane kwamasignali aseduze, namazinga aphansi wephutha lebhithi yesistimu.

 

Ukuvumelana nezimo
Ama-VCXO afinyelela imvamisa yokudonsa esebenzisa i-varactor diode, elungisa imvamisa yokuphuma nge-voltage yokulawula yangaphandle (imvamisa engu-0.5V ukuya ku-3.3V). Ibanga lokudonsa libonisa ukuchezuka kwefrikhwensi enkulu elungisekayo.

 

I-Ultra-I-Low Jitter
I-Jitter ukungaqiniseki kwesikhathi konqenqema lwesignali yewashi, kukalwa ngama-picosecond (ps). I-jitter ephansi iqinisekisa ukunemba kwesikhathi sesistimu futhi inciphisa izilinganiso zamaphutha amancane.

 

Ukuqina Kwezinga Lokushisa
Ukuchezuka kwemvamisa kungalawuleka ngaphakathi kuka-±25ppm ngaphansi kwamazinga okushisa adlulele, kuyenze ihambisane-nama-chips wesilawuli sezinga lezimboni ezifana ne-TI Sitara ne-STM32H7.

 

Uhlobo lwe-Low Phase Noise VCXO Oscillator 7 X 5

 

I-Quartz Crystal VCXOs

Besebenzisa ikristalu ye-quartz njenge-resonator, basebenzisa umphumela wayo we-piezoelectric kanye nezakhiwo ezinzile zokudlidliza kwemishini ukuze bakhiqize amaza. Zisetshenziswa ezinhlelweni ezifana neziteshi eziyisisekelo ze-5G, imishini yenethiwekhi ye-optical, kanye nokuzulazula kwesathelayithi, lapho ubumsulwa bemvamisa bubaluleke kakhulu.

 

MEMS (Micro-Electro-Mechanical System) VCXOs

Ukushintsha amakristalu e-quartz ngamaresonatha e-MEMS (njengezakhiwo ze-silicon-ezisekelwe), azuza ukukhiqizwa kwemvamisa ngokusebenzisa i-capacitive noma i-piezoresistive sensing. Ahlangene futhi asebenzisa amandla aphansi: ngokuvamile angaphansi kuka-10mW, okuwenza alungele amadivayisi aphathekayo.

 

Izinhlelo zokusebenza ze-Low Phase Noise VCXO Oscillator 7 X 5

Iziteshi eziyisisekelo ze-5G
Khonza njengomthombo wesiginali yereferensi yamasekhethi okushintshashintsha kwedijithali, oqinisekisa ukuzinza-kokudluliswa kwedatha ngesivinini esikhulu.

 

Imishini yenethiwekhi ye-Optical
Ihlinzeka ngomthombo wewashi-ophansi we-jitter kuzixhumi ezibonakalayo zenethiwekhi engu-25G/100G ukuze kwehliswe ukuwohloka kwesignali.

Ividiyo nokusakaza

Amafrikhwensi ereferensi okukhiphayo afana no-148.5MHz no-297MHz ukuze afane namawashi ephikseli yevidiyo (isb, 27MHz ku-1080p). Umsindo wesigaba kufanele ube Ngaphansi noma ulingane no--115dBc/Hz ngokususa imvamisa engu-10kHz ukuze ugweme ukungingiza noma ukuklebhuka kwesithombe.

Ukuhlolwa nokulinganisa

Ihlinzeka{0}ngomthombo wewashi onembe kakhulu ukuze kuqinisekiswe imiphumela yokulinganisa enembile. Kumasistimu wokuzulazula ngesathelayithi namasistimu okulawula indiza, imelana nezimo zokushisa ezeqisayo futhi inikeza ukulawulwa kwamafrikhwensi okuzinzile.

I-Automation yezimboni

Gcina ukuzinza phakathi kuka-±25ppm-ezindaweni zezinga lokushisa eliphezulu (-40℃ukuya ku-+85℃) futhi ahambisana nama-industrial-grade control chips afana ne-TI Sitara ne-STM32H7.

Izinyathelo Zokuqapha Ngesikhathi Sokusetshenziswa Kwesigaba Esiphansi Somsindo we-VCXO Oscillator 7 X 5

 

Control Voltage (Vc) Imininingwane

Ibanga lamandla kagesi:Namathela ngokuqinile kububanzi be-Vc obucaciswe kudatha yedatha (isb, 0.5V ukuya ku-3.3V). Ukweqa lobu bubanzi kungase kubangele i-frequency offset noma umonakalo.
Ukuthuthukiswa Komugqa:Uma-ukulawula ukunemba okuphezulu kudingeka, engeza i-op amp ukuze ubhafa isignali ye-Vc ukuze unciphise imithelela yokulayisha.
Ukunciphisa Umsindo:Khipha ulayini we-Vc kude-kumasignali anesivinini futhi wengeze ubuhlalu be-ferrite ukuze buhlungwe.

Ukuphathwa Kwezinga Lokushisa

Idizayini Yokukhipha Ukushisa: High-power VCXOs (e.g., >1W) zidinga usinki wokushisa noma i-thermal pad ukuze kuqinisekiswe izinga lokushisa lendawo ehlanganayo Lingaphansi noma lilingana no-85 degree.
Isinxephezelo Sezinga lokushisa:Uma izinga lokushisa le-ambient lishintshashintsha kakhulu, nika amandla umsebenzi we-TCXO noma xhuma inzwa yangaphandle yezinga lokushisa ukuze uthole isinxephezelo esiguqukayo.

Mechanical Stress Prevention

Indlela yokukhweza:Gwema ukucindezela okuqondile phezulu kwe-VCXO (okungase konakalise ikristalu). Kunconywa isokhethi noma i-SMD soldering.
Ukudlidliza Isolation:Okokusebenza kwezimoto noma kwe-aerospace, engeza amaphedi{0}}amunca ukushaqeka ukuze unciphise umthelela wokudlidliza komshini kumafrikhwensi.

 

Isondlo kanye nokuhlolwa
 

Ukulinganisa Okuvamile

Ukulinganisa Imvamisa:Okungenani kanye ngonyaka, sebenzisa ikhawunta yokubala (efana ne-Agilent 53132A) ukuze uqinisekise ukuthi imvamisa yokuphumayo ingaphakathi kwenani elivamile ± ibanga{1}}lokudonsa phezulu.
Isigaba Sokuhlolwa Komsindo:Njalo eminyakeni emibili, sebenzisa i-spectrum analyzer (efana ne-R&S FSWP) noma imitha yomsindo wesigaba (njenge-Keysight E5052B) ukuze uqinisekise imininingwane.

Ukuxazulula inkinga

Akukho okukhiphayo:Hlola ukuthi ingabe i-voltage yokuhlinzeka amandla kanye ne-Vc kungaphakathi kwebanga nokuthi i-soldering ikhululekile yini.
I-Frequency Drift:Qinisekisa ukuthi izinga lokushisa liyaweqa yini umkhawulo noma-i-voltage yokudonsa phezulu ayijwayelekile.
Isigaba Sokuwohloka Komsindo:Hlola umsindo wokunikezwa kwamandla, ukwehluleka kokuvikela, noma imithombo yokuphazamiseka eqinile eseduze.

Izimo Zokugcina

Izinga lokushisa kanye Nomswakama:Indawo yokugcina kufanele ilawulwe phakathi kuka -10℃kanye +60℃, enomswakama Ongaphansi noma olingana no-60% ukuze kuvinjelwe ukumuncwa komswakama yikristalu nokukhukhuleka kwamafrikhwensi.
I-Anti-I-Static:Gqoka ibhande-eliqinile esihlakaleni phakathi nokusebenza ukuze uvimbele ukulimala kwe-ESD kumasekhethi azwelayo.
