The Evolution ho tloha ho Standard Crystal Oscillators ho ea ho TCXO le OCXO
Tsoelo-pele ho tloha ho li-crystal oscillator tse tloaelehileng ho ea ho mocheso-compensated crystal oscillator (TCXOs) le oven-controlled crystal oscillator (OCXOs) e bonts'a ts'ebetso e tsoelang pele ea batho ea ho boloka botsitso le taolo e nepahetseng libakeng tse fapaneng tsa ts'ebeliso.
Ka 1921, Walter Guyton Cady o ile a fumana hore likristale tsa quartz li ka sebetsa e le li-resonator, tse bontšang tsoalo ea oscillator e tloaelehileng ea kristale. Leha ho nepahala ha eona khafetsa e bile ntlafatso e kholo ho feta li-oscillator tsa pejana, e ile ea lula e ts'oaroa habonolo ke mefuta e fapaneng ea mocheso, e lebisang ho hoholeha ha maqhubu.
Kaha libaka tse kang likhokahano tsa mehala le lits'ebetso tsa sesole li hloka botsitso bo boholo ba oscillator, thempereichara-compensated crystal oscillator (TCXO) e ile ea ntlafatsoa. TCXO e kenyelletsa potoloho ea matšeliso e sebelisang mocheso-likarolo tsa ho utloa, joalo ka li-thermistor, ho lokisa maqhubu a tlhahiso ka nako ea nnete, ho sebetsana ka katleho le ho kheloha ha maqhubu ho bakoang ke ho fetoha ha mocheso le ho boloka tlhahiso e tsitsitseng ea maqhubu tlas'a maemo a fapaneng a mocheso.
Bakeng sa lits'ebetso tse hlokang ho nepahala le ho feta, onto-controlled crystal oscillator (OCXO) e entsoe le ho hloekisoa. OCXO e boloka kristale ka har'a ontong e laoloang hantle, e e boloka e le mocheso o sa feleng. Mokhoa ona o fokotsa haholo phello ea ho fetoha ha mocheso ka ntle ho botsitso ba maqhubu. Ka lebaka leo, li-OCXO li fana ka botsitso bo betere ho feta li-crystal oscillator tse tloaelehileng le li-TCXO, hammoho le botsitso ba nako e telele{{4}le likarolo tse tlase tsa lerata.
Phetoho ena ea theknoloji e bakoa ke tlhokahalo e ntseng e hola ea ho nepahala, botsitso, le ho ts'epahala taolong ea khafetsa ka har'a litsamaiso tse tsoetseng pele tsa elektroniki. Sepheo e bile ho hlahisa li-oscillator tse khonang ho sebetsa maemong a ntseng a rarahana le ho ba boima, ho fihlela litlhoko tse thata tsa lits'ebetso tse kang likhokahano tsa sathelaete, litsamaiso tsa boemo ba lefatše (GPS), le{1}}marang-rang a lebelo a holimo.
Lilemong tsa morao tjena, boqapi bo ntse bo tsoela pele: li-oven tse peli-controlled crystal oscillator (DOCXOs) li na le botsitso bo matlafalitsoeng; Theknoloji ea matšeliso ea dijithale e 'nile ea kenyelletsoa ka ho eketsehileng ho TCXOs le OCXOs ka bobeli ho ntlafatsa tshebetso; le tekhenoloji e nyenyane{{1}ea electromechanical system (MEMS) e butse litsela tse ncha bakeng sa ho etsa hore ho be bonolo ho etsa hore ho be bonolo le ho etsa hore ho be le lisebelisuoa tsa kristale.
