Phokoso Lapansi Kwambiri
Phokoso la gawo ndi muyeso wa jitter ya gawo la siginecha ya pafupipafupi, yoyezedwa mu dBc/Hz (mphamvu yaphokoso pa bandwidth ya Hz poyerekeza ndi mphamvu yonyamula). Phokoso lotsika limatanthawuza mawonekedwe oyeretsa, kusokoneza pang'ono ndi ma sigino oyandikana nawo, komanso kutsika kwa zolakwika zapadongosolo.
Kusinthasintha
VCXOs amakwaniritsa kukoka pafupipafupi pogwiritsa ntchito diode ya varactor, kusintha ma frequency otuluka kudzera pamagetsi owongolera kunja (nthawi zambiri 0.5V mpaka 3.3V). Kukoka kwamitundu kumawonetsa kusinthasintha kosinthika pafupipafupi.
Ultra-Low Jitter
Jitter ndi kusatsimikizika kwa nthawi kwa m'mphepete mwa chizindikiro cha wotchi, yoyezedwa ndi ma picoseconds (ps). Low jitter imatsimikizira kulondola kwa nthawi yadongosolo ndikuchepetsa kulakwitsa pang'ono.
Kutentha Kukhazikika
Kupatuka kwapang'onopang'ono kungawongoleredwe mkati mwa ±25ppm kutentha kwambiri, kupangitsa kuti igwirizane ndi tchipisi tamakampani-magiredi monga TI Sitara ndi STM32H7.

Quartz Crystal VCXOs
Pogwiritsa ntchito kristalo wa quartz ngati resonator, amawonjezera mphamvu yake ya piezoelectric komanso kugwedezeka kwa makina kuti apange ma frequency. Amagwiritsidwa ntchito ngati masiteshoni a 5G, zida zama netiweki zowoneka bwino, ndikuyenda pasatana, komwe kuyeretsa pafupipafupi ndikofunikira kwambiri.
MEMS (Micro-Electro-Mechanical System) VCXOs
Kusintha makhiristo a quartz ndi ma resonator a MEMS (monga silicon-based beam structures), amatha kupanga ma frequency kudzera pa capacitive kapena piezoresistive sensing. Ndiwophatikizika ndipo amagwiritsa ntchito mphamvu zochepa: nthawi zambiri zosakwana 10mW, zomwe zimawapangitsa kukhala oyenera pazida zonyamula.
Malo oyambira a 5G
Imagwira ntchito ngati gwero la ma siginoloji a ma circuit modulation, kuonetsetsa kuti{0}}kutumiza kwa data mwachangu.
Zida zamagetsi zamagetsi
Amapereka-otchi yocheperako mu 25G/100G netiweki kuti achepetse kuwonongeka kwa ma siginecha.
Kanema ndi kuwulutsa
Kutulutsa kwanthawi yayitali monga 148.5MHz ndi 297MHz kuti agwirizane ndi mawotchi a pixel a kanema (mwachitsanzo, 27MHz pa 1080p). Phokoso la gawo liyenera kukhala Lochepera kapena lofanana ndi -115dBc/Hz pa 10kHz pafupipafupi kuchepetsa kuti chithunzi chisachite chibwibwi kapena kung'ambika.
Kuyesa ndi kuyeza
Amapereka-wotchi yolondola kwambiri kuti atsimikizire zotsatira zolondola. M'mayendedwe a satellite navigation ndi kayendedwe ka ndege, imalimbana ndi malo otentha kwambiri ndipo imapereka kuwongolera pafupipafupi.
Industrial automation
Sungani bata mkati mwa ±25ppm potentha-malo otentha kwambiri (-madigiri 40 mpaka +85 digiri ) ndipo zimagwirizana ndi tchipisi tamakampani monga TI Sitara ndi STM32H7.
Kusamala Pa Kugwiritsa Ntchito Low Phase Phokoso VCXO Oscillator 7 X 5
Mtundu wa Voltage:Tsatirani mosamalitsa kusiyanasiyana kwa Vc komwe kumatchulidwa mu datasheet (mwachitsanzo, 0.5V mpaka 3.3V). Kupyola mulingo uwu kungayambitse kusokoneza pafupipafupi kapena kuwonongeka.
Linearity Optimization:Ngati pakufunika kuwongolera bwino kwambiri-, onjezani op amp kuti muteteze siginecha ya Vc kuti muchepetse kutsitsa.
Kuchepetsa Phokoso:Chotsani mzere wa Vc kutali- ndi ma siginecha akuthamanga kwambiri ndikuwonjezera mikanda ya ferrite kuti musefe.
Mapangidwe a Kuwotcha Kutentha: High-power VCXOs (e.g., >1W) imafuna choyamwitsa chotenthetsera kapena chotenthetsera chotenthetsera kuti kutentha kwa mphambano ndikochepera kapena kofanana ndi madigiri 85.
Malipiro a Kutentha:Ngati kutentha yozungulira kusinthasintha kwambiri, athe TCXO ntchito kapena kulumikiza kunja kutentha sensa kwa chipukuta misozi zazikulu.
Njira Yoyikira:Pewani kuthamanga kwachindunji pamwamba pa VCXO (zomwe zingawononge kristalo). Socket kapena SMD soldering ikulimbikitsidwa.
Kudzipatula kwa Vibration:Pazida zamagalimoto kapena zamumlengalenga, onjezani ma shock-pads kuti muchepetse kugwedezeka kwa makina pafupipafupi.
Kusamalira ndi Kuyesa
Nthawi zonse Calibration
Kuwongolera pafupipafupi:Pafupifupi kamodzi pachaka, gwiritsani ntchito makina owerengera pafupipafupi (monga Agilent 53132A) kuti mutsimikize kuti kutulutsa kwake kuli mkati mwa mtengo wake ± kukoka-kumtunda.
Mayeso a Phase Noise:Zaka ziwiri zilizonse, gwiritsani ntchito spectrum analyzer (monga R&S FSWP) kapena mita ya phokoso la gawo (monga Keysight E5052B) kuti mutsimikizire zomwe mukufuna.
Kusaka zolakwika
Palibe zotuluka:Yang'anani ngati magetsi amagetsi ndi Vc ali mkati mwamtunduwo komanso ngati soldering ndi yotayirira.
Frequency Drift:Tsimikizirani ngati kutentha kwadutsa malirewo kapena -voltage yokwera ndi yachilendo.
Kuwonongeka kwa Phase Noise:Yang'anani phokoso lamagetsi, kulephera kwa chitetezo, kapena magwero amphamvu osokoneza pafupi.
Zosungirako
Kutentha ndi Chinyezi:Malo osungira akuyenera kuyendetsedwa pakati pa -10 digirii ndi +60 madigiri , ndi chinyezi Chochepera kapena chofanana ndi 60% kuti chisamayamwitse chinyezi ndi kristalo ndi kutengeka pafupipafupi.
Anti-Zokhazikika:Valani anti-lamba pamanja mukamagwira ntchito kuti mupewe kuwonongeka kwa ESD pamagawo okhudzidwa.
