Oven Controlled Crystal Oscillator (OCXO)

The Oven Controlled Crystal Oscillator (OCXO) ndi kristalo oscillator yomwe imagwiritsa ntchito thanki yotentha nthawi zonse kuti kutentha kwa quartz crystal resonator mu crystal oscillator nthawi zonse, ndi kusintha kwafupipafupi kwa oscillator chifukwa cha kusintha kwa kutentha kumachepetsedwa kukhala osachepera. . OCXO imapangidwa ndi dera lowongolera kutentha kwa thanki ndi dera la oscillator, nthawi zambiri limagwiritsa ntchito "mlatho" wopangidwa ndi masiyanidwe amplifier kuti akwaniritse kutentha.

Lili ndi izi:

1.Ntchito yolipirira kutentha kwamphamvu: OCXO imakwaniritsa kubwezera kwa kutentha kwa oscillator pogwiritsa ntchito zinthu zozindikira kutentha ndi mabwalo okhazikika. Imatha kukhalabe ndi kukhazikika kwafupipafupi pafupipafupi kutentha kosiyanasiyana.
2. Kukhazikika kwafupipafupi: OCXO nthawi zambiri imakhala yokhazikika pafupipafupi, kusinthasintha kwake kumakhala kochepa komanso kokhazikika. Izi zimapangitsa OCXO kukhala yoyenera kugwiritsa ntchito zomwe zili ndi zofunikira pafupipafupi.
2.Kuyambira nthawi yofulumira: Nthawi yoyambira ya OCXO ndi yaifupi, kawirikawiri ndi ma milliseconds ochepa chabe, omwe amatha kukhazikika mofulumira maulendo otuluka.
3. Kugwiritsa ntchito mphamvu pang'ono: Ma OCXO nthawi zambiri amadya mphamvu zochepa ndipo ndi oyenera kugwiritsa ntchito mphamvu zolimba kwambiri, zomwe zimatha kupulumutsa mphamvu ya batri.
OCXO imagwiritsidwa ntchito kwambiri polumikizana ndi mafoni, kulumikizana ndi satana, kutumiza ma data opanda zingwe ndi magawo ena kuti apereke ma frequency okhazikika. 2. Mawonekedwe ndi ma navigation systems: M'mapulogalamu monga GPS ndi Beidou navigation System, OCXO imagwiritsidwa ntchito popereka zizindikiro zolondola za wotchi, zomwe zimathandiza kuti dongosololi lizitha kuwerengera molondola malo ndi nthawi yoyeza. 3. Zida: Pazida zoyezera molondola ndi zida, OCXO imagwiritsidwa ntchito popereka zizindikiro zolondola za wotchi kuti zitsimikizire kulondola ndi kubwereza zotsatira zoyezera. 4. Zipangizo zamagetsi: OCXO imagwiritsidwa ntchito kwambiri pamayendedwe a wotchi yamagetsi kuti apereke nthawi yokhazikika ya wotchi kuti azitha kugwira ntchito bwino pa chipangizocho. Mwachidule, OCXO ili ndi mawonekedwe achitetezo champhamvu cha kutentha, kukhazikika kwafupipafupi, nthawi yoyambira mwachangu komanso kugwiritsa ntchito mphamvu zochepa, zomwe ndizoyenera kugwiritsa ntchito zomwe zimafunikira pafupipafupi komanso kukhudzidwa ndi kusintha kwa chilengedwe.
