Oven Controlled Crystal Oscillator (OCXO)

The Oven Controlled Crystal Oscillator (OCXO) ndi crystal oscillator yomwe imagwiritsa ntchito thanki yotentha nthawi zonse kuti isunge kutentha kwa quartz crystal resonator mu crystal oscillator nthawi zonse, ndi kusintha kwafupipafupi kwa oscillator chifukwa cha kusintha kwa kutentha komwe kumakhala kochepa. 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. Mphamvu yolipirira kutentha kwamphamvu: OCXO imakwaniritsa kubwezera kutentha kwa oscillator pogwiritsa ntchito zinthu zozindikira kutentha ndi mabwalo okhazikika. Imatha kukhalabe ndi kutulutsa pafupipafupi kokhazikika pamatenthedwe osiyanasiyana.
2. Kukhazikika kwafupipafupi: OCXO nthawi zambiri imakhala ndi kukhazikika kwafupipafupi kolondola kwambiri, kupatuka kwake pafupipafupi kumakhala kochepa komanso kokhazikika. Izi zimapangitsa kukhazikika kwapafupipafupi kwa OCXO kukhala koyenera kwa mapulogalamu omwe ali ndi zofunika pafupipafupi.
3. Nthawi yoyambira mwachangu: Nthawi yoyambira ya OCXO ndi yaifupi, nthawi zambiri ndi ma milliseconds ochepa, omwe amatha kukhazikika mwachangu pafupipafupi.
4. 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.

Ntchito za Oven Controlled Crystal Oscillators:

1. Njira zoyankhulirana: OCXO imagwiritsidwa ntchito kwambiri poyankhulana ndi mafoni, mauthenga a satana, kutumiza ma data opanda zingwe ndi madera ena kuti apereke maulendo owerengeka 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.
