Ezweni lama-electronics, ukuba nezingxenye ezinembayo kubalulekile ukuze kuqinisekiswe ukusebenza kahle kwanoma iyiphi isekethe. Enye yezinto ezibalulekile zokufeza lokhu yi- amakristalu oscillating kanye resonators Ceramic, ikakhulukazi lawo anemvamisa ye 16 MHz, njengephakeji elidumile le-HC-49S noma i-CSTCE16M0V53 resonator yobumba. Nakuba zingase zibonakale zifana ekuqaleni, ngayinye yenza imisebenzi ethile ezenza zifanelekele izinhlelo zokusebenza ezihlukene.
Ukwazi umehluko phakathi kwalezi zingxenye kanye nokuqonda ukuthi zisebenza kanjani kungaba ukhiye ekukhetheni okulungile kumaphrojekthi akho e-elekthronikhi. Kulesi sihloko, sizobheka yonke imininingwane ebalulekile mayelana nezingxenye. Amakristalu e-piezoelectric e-HC-49S kanye nemodeli I-CSTCE16M0V53, kusukela ezicini zayo kuya ekusetshenzisweni kwayo okuvame kakhulu kumadivayisi esimanje.
Iyini i-crystal oscillator futhi isebenza kanjani?
Un i-crystal oscillator kusekelwe ku i-resonance mechanical Impahla ye-piezoelectric, ngokuvamile i-quartz, isetshenziselwa ukukhiqiza isignali kagesi yefrikhwensi enembile. Lesi simo senzeka lapho ikristalu idlidliza lapho ithola ukushajwa kukagesi, ikhiqiza imvamisa ezinzile engasetshenziswa njengewashi noma isignali yesikhathi kumasekhethi edijithali. Ukuze unwebe ulwazi lwakho mayelana nendlela yokuhlola nokuqinisekisa lezi zingxenye, ungathintana nomhlahlandlela wethu kokuthi indlela yokuhlola izingxenye ze-elekthronikhi.
Imodeli I-HC-49S Ingenye yamaphakheji avame kakhulu kulawa makristalu. Inezikhonkwane ezimbili, ukumelana nochungechunge olusebenzayo cishe okungama-ohms angama-30, a imvamisa yokusebenza 16 MHz ngokubekezelela +/- 20 ppm namandla asondele ku-20 pF. Inesisindo esingamagremu angu-2, okuyenza ilungele amadivayisi angenayo imikhawulo yosayizi oqinile.
Ama-Ceramic resonators: enye indlela eguquguqukayo
Ngaphambi kwengilazi ye-HC-49S, sithola futhi ama-resonator e-ceramic njenge I-CSTCE16M0V53-R0, imodeli enikeza ukusebenza okufanayo, kodwa ngendlela ehlukile. Le ngxenye yaziswa kabanzi ngekhono layo loku khiqiza i-frequency oscillation ezinzile ngokudlidliza kwento yobumba esikhundleni se-quartz. Esihlokweni Izinhlobo zama-oscillator e-MEMS nokuningi ungangena ujule kubuchwepheshe bayo obuhlukene.
Lezi resonator zisetshenziselwa isikhathi, ukulawula imvamisa nokucubungula isignali ezinhlobonhlobo zezinto zikagesi. Ukusetshenziswa kwayo kuvamile emikhakheni efana ne-electronics yabathengi, izimoto, kanye namasistimu ashumekiwe asuselwa ku-microcontroller.
