The Oven Sarrafa Crystal Oscillator (OCXO)

The Oven Sarrafa Crystal Oscillator (OCXO) ne crystal oscillator cewa yana amfani da akai zazzabi tanki don kiyaye zafin jiki na ma'adini crystal resonator a cikin crystal oscillator akai-akai, da oscillator fitarwa mita canji lalacewa ta hanyar yanayi zazzabi canji an rage zuwa mafi m. OCXO yana kunshe da da'irar kula da tankin zafin jiki akai-akai da da'irar oscillator, yawanci ta yin amfani da "gada" ta thermistor wanda ya ƙunshi nau'in amplifier daban-daban don cimma ikon sarrafa zafin jiki.

Yana da halaye kamar haka:

1. Ƙarfin aikin ramuwa na zafin jiki: OCXO yana samun ramuwar zafin jiki ga oscillator ta amfani da abubuwan gano zafin jiki da daidaitawa da'ira. Yana da ikon kiyaye ingantaccen fitowar mitar mitoci a yanayin zafi daban-daban.
2. Babban mitar kwanciyar hankali: OCXO yawanci yana da daidaiton daidaiton mitar mitar, rarrabuwar mitar ƙarami ne kuma ingantacciyar kwanciyar hankali. Wannan yana sa babban mitar kwanciyar hankali OCXO ya dace da aikace-aikace tare da buƙatun mitar mai girma.
3. Lokacin farawa da sauri: Lokacin farawa na OCXO gajere ne, yawanci 'yan millise seconds kawai, wanda zai iya daidaita saurin fitarwa.
4. Karancin amfani da wutar lantarki: OCXOs yawanci suna cinye ƙarancin wuta kuma sun dace da aikace-aikace tare da ƙarin buƙatun wutar lantarki, wanda zai iya adana ƙarfin baturi.

Aikace-aikacen Crystal Oscillators Mai Sarrafa Tanda:

1. Tsarin sadarwa: OCXO ana amfani dashi sosai a cikin sadarwar wayar hannu, sadarwar tauraron dan adam, watsa bayanai mara igiyar waya da sauran fagage don samar da ingantaccen mitar tunani.
2. Tsarin matsayi da kewayawa: A aikace-aikace kamar GPS da Beidou kewayawa System, OCXO ana amfani da shi don samar da ingantattun siginar agogo, yana ba na'urar damar ƙididdige matsayi daidai da auna lokaci.
3. Kayan aiki: A cikin ma'auni na ma'auni da kayan aiki, ana amfani da OCXO don samar da daidaitattun sigina na agogo don tabbatar da daidaito da sake fasalin sakamakon aunawa.
4. Kayan lantarki: OCXO ana amfani dashi sosai a cikin agogo na kayan lantarki don samar da mitar agogo mai tsayayye don ba da damar aiki na yau da kullun na na'urar.

A takaice, OCXO yana da halaye na aikin ramawa mai ƙarfi na zafin jiki, kwanciyar hankali mai ƙarfi, saurin farawa da ƙarancin wutar lantarki, wanda ya dace da aikace-aikace tare da buƙatun mitar mai girma da kula da canjin yanayin yanayin zafi.

Qualwaveyana ba da ƙaramar amo OCXO.
