Ubwino wa VCXO Oscillators
Zabwino-Kutha Kukonza
Ma VCXO amalola kusintha kolondola kwa ma frequency otuluka kudzera mumagetsi owongolera omwe amagwiritsidwa ntchito. Kukonza bwino kumeneku-ndikofunikira pamapulogalamu monga matelefoni ndi mauthenga pa data, pomwe nthawi yeniyeni ndi kulunzanitsa ndikofunikira.
Kukhazikika Kwambiri
Ma kristalo a quartz mu VCXO amapereka kukhazikika kwafupipafupi pafupipafupi pa kutentha kosiyanasiyana komanso chilengedwe. Izi zimatsimikizira magwiridwe antchito odalirika pamapulogalamu ofunikira.
Low Phase Noise
Ma VCXO nthawi zambiri amakhala ndi phokoso lotsika, lomwe ndi lofunika kwambiri kuti ma siginolo akhale omveka bwino-panthawi zambiri. Phokoso la gawo lotsika limapangitsa kuti machitidwe onse azilumikizana bwino komanso achepetse zolakwika.
Kusinthasintha
Ma VCXO ndi osinthika ndipo amatha kugwiritsidwa ntchito m'mapulogalamu osiyanasiyana, kuphatikiza kulumikizana ndi netiweki, gawo-zotsekeka zotsekera (PLLs), komanso kusinthasintha kwafupipafupi pokonza ma siginolo.
Yocheperako komanso Yothandiza
Ma VCXO ndi ang'onoang'ono komanso amphamvu-amagwira ntchito moyenera, zomwe zimapangitsa kuti zikhale zoyenera kuphatikizidwa ndi zida zamakono zamagetsi momwe malo ndi magetsi ndizofunikira kwambiri.
Mtundu wa VCXO Oscillators
Zithunzi za Basic VCXO
Onetsani ma voltage okhawo-controlled frequency control, popanda kubweza kutentha kapena kutentha kosasintha. Ndioyenera kutengera mtengo-mapulogalamu osavuta kumva okhala ndi kutentha kokhazikika, monga mawotchi amagetsi ogula (ma foni a m'manja ndi matabuleti).
Kutentha-kulipidwa ma VCXO (TC-VCXOs)
Gwirizanitsani zozungulira kutentha (zachindunji kapena zosalunjika) kuti zikhale zolondola kwambiri pa kutentha kwapakati pa -madigiri 40 mpaka +85 madigirii . Ndioyenera malo olumikizirana m'manja, makina oyendera ma satelayiti, ndi zida zolondola kwambiri.
Ovuni-ma VCXO olamulidwa (OC-VCXOs)
Ikani kristalo ndi oscillator dera mu chipinda cha kutentha kosalekeza kuti athetse zotsatira za kutentha, kukwaniritsa kulondola kwafupipafupi pa dongosolo la 10⁻⁷. Ndizoyenera kugwiritsa ntchito zomwe zimafuna kukhazikika kwapamwamba kwambiri, monga chitetezo, navigation, ndi zowerengera pafupipafupi.
Ntchito za VCXO Oscillators
Matelefoni:M'matelefoni, ma VCXO amagwiritsidwa ntchito kupanga mawotchi okhazikika, olondola omwe amagwirizanitsa kufalitsa ndi kulandira pakati pa zipangizo. Ndiwothandiza makamaka pamapulogalamu omwe amafunikira nthawi yolondola, monga makina olumikizirana opanda zingwe, ma base station, ndi ma satellite communications.
Kulumikizana ndi Data:Njira zoyankhulirana ndi data zimafuna mawotchi olondola kuti atsimikizire kutumiza kodalirika kwa data. Ma VCXO amatha kugwiritsidwa ntchito m'makinawa kuti apange mawotchi olondola komanso okhazikika, ngakhale pakakhala phokoso ndi zosokoneza zina. Amagwiritsidwa ntchito nthawi zambiri pamapulogalamu monga ma switch a Ethernet, ma routers, ndi zida zina zamaneti.
Zida Zoyesera ndi Zoyezera:Pazida zoyesera ndi zoyezera, ma VCXO amagwiritsidwa ntchito kupanga ma siginecha olondola omwe amagwiritsidwa ntchito poyesa ndi kuyesa zida zina. Ndiwothandiza makamaka pamapulogalamu omwe amafunikira kulondola kwambiri komanso kukhazikika, monga ma frequency counter, ma spectrum analyser, ndi ma oscilloscopes.
GPS Receivers:Zolandila za Global Positioning System (GPS) zimagwiritsa ntchito ma VCXO kupanga masigino olondola a nthawi omwe amagwiritsidwa ntchito kuwerengetsera komwe wolandilayo ali. VCXO imagwiritsidwa ntchito kupanga chizindikiro chokhazikika cha wotchi chomwe chimalumikizidwa ndi chizindikiro cha satellite ya GPS.
Zida Zomvera ndi Makanema:Pazida zomvera ndi makanema, ma VCXO amagwiritsidwa ntchito kupanga mawotchi omwe amalumikizana ndi magawo osiyanasiyana adongosolo. Mwachitsanzo, VCXO ingagwiritsidwe ntchito kupanga chizindikiro cha wotchi yomwe imagwirizanitsa chizindikiro cha kanema ndi siginecha yomvera m'nyumba ya zisudzo.
Makina Oyang'anira Mafakitale:M'mafakitale olamulira, ma VCXO amagwiritsidwa ntchito kupanga mawotchi omwe amagwirizanitsa ntchito zamagulu osiyanasiyana mu dongosolo. Amagwiritsidwa ntchito kwambiri pamapulogalamu monga programmable logic controllers (PLCs) ndi makina owongolera magalimoto.
Military and Aerospace Systems:Zida zankhondo ndi zakuthambo zimafunikira zizindikiro zolondola za nthawi yolumikizirana, kuyenda, ndi ntchito zina zofunika. Ma VCXO amagwiritsidwa ntchito kwambiri m'makinawa kuti apange mawotchi okhazikika omwe amakwaniritsa zofunikira zodalirika komanso zolondola pamapulogalamuwa.
Zida Zachipatala:Pazida zamankhwala, ma VCXO amagwiritsidwa ntchito kupanga mawotchi omwe amalumikizana ndi magawo osiyanasiyana adongosolo. Amagwiritsidwa ntchito nthawi zambiri pamakina a ultrasound, makina ojambulira a MRI, ndi zida zina zowunikira zomwe zimafuna nthawi yolondola komanso kuyanjanitsa.
Pamtima pa VCXO pali chozungulira chomwe chimakhala ndi capacitor ndi inductor. Kuchuluka kwa resonant kwa dera lino kumatsimikiziridwa ndi mfundo za capacitor ndi inductor. Mwa kuwongolera mphamvu kapena inductance ya resonant dera, ma frequency a oscillator amatha kusinthidwa.
Mu VCXO, dera la resonant limapangidwa ndi kristalo. Ma kristalo amapangidwa kuti azigwedezeka pafupipafupi pomwe gawo lamagetsi likugwiritsidwa ntchito modutsa. Ma kristalo amalumikizidwa ndi dera la amplifier lomwe limakulitsa kugwedezeka kwa kristalo, komwe kumapangitsanso kutulutsa kwa sine wave.
Kutulutsa pafupipafupi kwa VCXO kumatha kuwongoleredwa pogwiritsa ntchito magetsi owongolera ku diode ya varactor limodzi ndi kristalo. The varactor diode amasintha mphamvu yake poyankha magetsi ogwiritsidwa ntchito, omwe amasintha ma frequency a resonant a kristalo. Izi zimapangitsa kuti ma frequency amtundu wotuluka asinthe.
Kuchuluka kwakusintha pafupipafupi pagawo lililonse lamagetsi ogwiritsidwa ntchito kumadziwika kuti VCXO's tuning sensitivity. Kukhudzika kwa kusintha kungasinthidwe posintha kukondera kwa DC komwe kumagwiritsidwa ntchito pa varactor diode.
