Enkulaakulana okuva ku Standard Crystal Oscillators okutuuka ku TCXO ne OCXO
Okukulaakulana okuva ku standard crystal oscillators okutuuka ku temperature-compensated crystal oscillators (TCXOs) ne oven-controlled crystal oscillators (OCXOs) kiraga obuntu obutasalako okugoberera okutebenkera kwa frequency eya waggulu n’okufuga okutuufu mu mbeera ez’enjawulo ez’okukozesa.
Mu 1921, Walter Guyton Cady yakizuula nti kirisitaalo za quartz zisobola okukola nga resonators, ekiraga okuzaalibwa kwa standard crystal oscillator. Newankubadde nga obutuufu bwayo bwa frequency bwali bulongoofu bwa maanyi okusinga oscillators ezasooka, yasigala nga esobola okukyukakyuka mu bbugumu, ekyavaako frequency drift.
Nga ennimiro ng’empuliziganya n’okukozesa mu magye bwe zaali zeetaaga okutebenkera kwa oscillator okusingawo, temperature-compensated crystal oscillator (TCXO) yakolebwa. TCXO erimu ekiyungo ky’okuliyirira ekikozesa ebitundu ebitegeera ebbugumu-, nga thermistors, okutereeza frequency efuluma mu kiseera ekituufu, okuziyiza obulungi okukyama kwa frequency okuva mu nkyukakyuka mu bbugumu n’okukuuma okufuluma kwa frequency okunywevu ennyo mu mbeera z’ebbugumu ezitali zimu.
Ku nkola ezeetaaga obutuufu obusingako awo, oven-controlled crystal oscillator (OCXO) yakolebwa era n’erongoosebwa. OCXO etereka kirisitaalo mu oven efugibwa obulungi, n’egikuuma ku bbugumu eritakyukakyuka. Enkola eno ekendeeza nnyo ku buzibu obuva mu nkyukakyuka z’ebbugumu ery’ebweru ku kutebenkera kwa frequency. N’ekyavaamu, OCXOs ziwa obutebenkevu bwa frequency obulungi ennyo okusinga standard crystal oscillators ne TCXOs, awamu n’obutebenkevu obulungi ennyo obw’ekiseera ekiwanvu-n’engeri z’amaloboozi ga phase entono.
Enkulaakulana eno eya tekinologiya eva ku bwetaavu obweyongera obw’obutuufu, obutebenkevu, n’okwesigamizibwa mu kufuga frequency munda mu nkola z’ebyuma ez’omulembe. Ekigendererwa kibadde kya kukola oscillators ezisobola okukola mu mbeera ezigenda zeeyongera okuzibuwalirwa era ezisaba, okutuukiriza ebisaanyizo ebikakali eby’enkola enkulu nga empuliziganya ya setilayiti, enkola z’okulaga ebifo mu nsi yonna (GPS), n’emikutu gya digito egy’amaanyi-.
Mu myaka egiyise, obuyiiya bugenda mu maaso: dual oven-controlled crystal oscillators (DOCXOs) byongedde okutumbula obutebenkevu; tekinologiya w’okuliyirira mu ngeri ya digito yeeyongedde okugattibwa mu TCXO ne OCXO zombi okusobola okulongoosa omulimu; ne tekinologiya wa micro-electromechanical systems (MEMS) agguddewo amakubo amapya ag’okukendeeza n’okumenya omulimu mu biwujjo bya kirisitaalo.
