Kana zvasvika kune nguva uye frequency control zvishandiso, oscillator inoita basa rakakosha. Kubva pamashandisirwo enharembozha kuenda kune GPS masisitimu, maindasitiri sensors uye satellite, izvi zvikamu zvakakosha kuti uve nechokwadi kururama y kugadzikana. Nekudaro, nekuda kwekusiyana kwesarudzo dziripo, kunzwisisa marudzi akasiyana emaoscillator anogona kuvhiringa. Muchinyorwa chino tinopaza pasi zvakakosha zvemhando huru dze oscillator: MEMS, TCXO, OCXO, VCO, VCXO and the rubidium oscillators, kuongorora maitiro ayo, zvakanakira uye zvinowanzoitika.
Kusarudza oscillator yakarurama kunosanganisira kuongorora zvinhu zvakadai se kugadzikana, kururama, saizi y bhajeti. Zvakakosha kuve pachena kuti mhando yega yega ine maitiro ayo ehunyanzvi uye maitiro ekuita. Pazasi, isu tichaongorora mune imwe neimwe yeaya akasiyana kuti tikubatsire iwe kuita sarudzo ine ruzivo.
MEMS Oscillators: Compact uye Rugged Technology
ari MEMS oscillators (MicroElectroMechanical Systems) inoratidzirwa nekuve yakanyanya hupfumi uye nyore kuita. Yavo compact dhizaini uye mhedzisiro kuramba inovaita sarudzo yakanaka kune inotakurika zvishandiso kana maapplication. Internet yezvinhu (IoT). Ivo vanoshanda vachishandisa micromechanical resonators, kazhinji inogadzirwa nesilicon, iyo inodedera pane chaiyo frequencies kana magetsi amutswa.
Pakati pezvakanakira kugona kwayo kushanda mukati kupisa kwakanyanya kubva pakati -40 uye + 150 ° C, kushandiswa kwavo kwesimba shoma uye kushorwa kwavo kwemagetsi. Nekudaro, kugadzikana kwayo uye kurongeka kwakadzikira kana ichienzaniswa nemamwe marudzi emaoscillator, ayo anoganhurira kubatsira kwawo mumashandisirwo anoda. kururamisa kwepamusoro.
TCXO: Tembiricha Inobhadharwa Oscillators
Kana iwe uchitsvaga kugadzikana kwakanyanya pasina kusvetuka kwakakosha mumutengo, iyo TCXO (Temperature-Compensated Crystal Oscillator) isarudzo yakasarudzika. Aya quartz oscillators akagadzirirwa kugadzirisa iyo frequency variations kunokonzerwa nekushanduka kwekushisa kuburikidza nemasekete emubhadharo wemukati.
Kushanda kwayo kunosanganisira tembiricha kubva -40 kusvika +85°C, ine a kururama iyo inosiyana pakati pe0,1 ne2 ppm/°C, iri nani pane yakapihwa neMEMS. Aya maitiro anoita kuti TCXOs ive yakanaka kune zvikumbiro munharembozha, maindasitiri sensors uye GPS zvishandiso. Pasinei zvake kuita kwepamusoro, ramba uine compact uye simba rinoshanda.
OCXO: Kugadzikana kuburikidza nekupisa kwekutonga
Nezvezvikumbiro zvinoda kugadzikana kwakanyanya, OCXO (Oven-Controlled Crystal Oscillator) ndeyechipiri kune imwe. Vanoshanda nekuchengeta quartz crystal pa tembiricha yenguva dzose mukati mevheni diki, iyo inobvisa zvachose kusiyana kwefrequency kunokonzerwa nenharaunda.
Nekuda kweiyi tekinoroji yekudzora kupisa, OCXOs inopa frequency kugadzikana inosvika 0,01 ppm/°C uye hushoma hwepagore hwekudonha mwero we0,1 ppm. Nekudaro, saizi yavo yakakura, mashandisiro esimba repamusoro uye mutengo wakakwira unovaendesa kune nyanzvi dzekushandisa, senge mauto masisitimu, chiridzwa chesainzi kana nharembozha yepamusoro.
Voltage inodzorwa oscillators: VCO uye VCXO
ari VCO oscillators (Voltage-Controlled Oscillator) uye VCXO (Voltage-Controlled Crystal Oscillator) inokosha mumasisitimu anoda kugadzirisa frequency zvichienderana nechiratidzo chekunze chekudzora. Iyo VCO inoshandisa dhizaini yemagetsi kusiyanisa zvakananga frequency yayo, nepo VCXO inoshandisa quartz crystal yakasanganiswa necircuitry kuti inyatso kudzora.
Ose ari maviri akakosha mukufambiswa kwemashoko, chiratidzo chemodulation uye demodulation application, pamwe nemasisitimu ekutaurirana. kuwiriranisa.
Rubidium Oscillators: Affordable Atomic Clocks
Paunenge uchitaura nezvekunyanya kurongeka mune zvekutengesa zvishandiso, iyo rubidium oscillators Ndivo chirevo. Kusiyana nemamwe marudzi, haatsamiri pamakristasi equartz, asi pane atomic resonance ye rubidium. Izvi zvinovaita sarudzo yakanakira satellite, mashandisirwo esainzi uye masisitimu anoda a kugadzikana kunoshamisa mukureba
Aya maoscillator ane kudonha mitengo se pasi Chemhondoro 10-11 a 10-12 ppm/zuva, kuwana kuita kunodarika kure OCXO neTCXO. Nekudaro, mutengo wavo wakakwira uye saizi inovamisa kune chaiwo mashandisiro.
Sarudzo chaiyo ye oscillator zvinoenderana nezvinodiwa zvepurojekiti yako. Nepo MEMS yakanakira kuremesa, inotakurika maapplication, TCXOs uye OCXOs inokunda mune zvikumbiro zvinoda kugadzikana uye nemazvo. Kune chikamu chavo, rubidium oscillators inomiririra iyo yepamusoro yekurongeka kwenzvimbo uko bhajeti inobvumira. Tekinoroji innovation inoramba ichifambira mberi mundima iyi, ichibatanidza maficha akavandudzwa mukugadzirisa compact senge tembiricha-inotsiva MEMS inotokwikwidza yemhando yepamusoro quartz.
