Ni ibihe bice vy’ibikoresho vy’ubuhinga bwa none bikoreshwa n’ubushuhe (TCXO)?
Igikoresho co guhindura ubushuhe (TCXO) ni ubwoko bw’igikoresho co guhindura ubushuhe kigumya igisohoka c’incuro zidahinduka mu bihe vy’ubushuhe butandukanye. Ishiramwo umurongo wo gusubiza inyuma ubushuhe kugira ngo ugabanye ingaruka z’ihinduka ry’ubushuhe bwo mu bidukikije ku nkuru z’uguhungabana, bigatuma habaho ibimenyetso vy’isaha vy’ukuri cane-mu bidukikije bitandukanye. TCXOs zigabanywa cane cane mu mice itatu: indishi itaziguye, indishi itaziguye, n’indishi y’ubuhinga bwa none.
Ibirango rusangi vya TCXOs
Gushikama gukomeye: Bitanga incuro zidahinduka zisohoka ku rugero runini rw’ubushuhe, bikagabanya ingaruka z’uguhinduka kw’ubushuhe ku mikorere y’ibikoresho.
Ugutomora neza cane: Itanga ibimenyetso vy'isaha vy'ukuri cane-, bibereye ibikorwa bisaba igihe c'ukuri cane.
Inguvu zikoreshwa nke: Akenshi zikoreshwa n'inguvu nke mu bikoresho vy'amaboko n'ibikorwa bikoreshwa na bateri-kugira ngo bateri zibeho.
Urusaku rw’Igice Gito: Ivyiyumviro bimwebimwe vya TCXO na vyo nyene biratanga ibiranga urusaku rw’Igice Gito, ivyo bikaba ari ngirakamaro cane ku mirongo y’itumanaho n’ibindi bikoresho bishobora gushikirwa n’uguhungabana kw’ibimenyetso.
Indishi itaziguye TCXO
Igikoresho co gusubiza inyuma TCXO gikoresha umurongo w’ugusubiza inyuma ubushuhe ugizwe n’ibikoresho vy’ubushuhe n’ibintu bishobora guhangana n’ibindi, bifatanye mu buryo bukurikiranye n’igikoresho co gusubiza inyuma ubushuhe kiri mu gikoresho co guhindura ubushuhe. Iyo ubushuhe bwo mu karere buhindutse, ubushobozi bwo guhangana n’ubushuhe n’ubushobozi bw’urutonde bungana bw’ikibiriti birahinduka bivanye n’ivyo, gutyo bikagabanya canke bikagabanya ubushuhe bugenda buhinduka bw’incuro z’uguhungabana. Ubu buryo bwo gusubiza inyuma buratanga inyungu nk’uruzitiro rworoshe, igiciro gito, n’ubunini bw’uruzitiro rwacapuwe (PCB) n’ahantu bisabwa, bikaba bituma bubereye cane ku bikorwa bikomeye, bifise umuriro muto, n’ibikorwa bifise umuriro muto. Ariko rero, bishobora kutaba bihuye n’ibisabwa kugira ngo umuyagankuba w’amabuye y’agaciro ukore neza kurusha ±1 ppm.
Indishi itaziguye TCXO
Inyishu idatomoye y'analog: Ikoresha ibice bimenya ubushuhe-nk'ibikoresho vy'ubushuhe kugira ngo bikore umurongo w'uguhindura ubushuhe-ku -umuriro. Ivyo bikoresho bikoreshwa ku diode varactor ifatanye mu buryo bukurikirana n’igikoresho co gutera ijwi ry’ikibiriti. Ihinduka ry’ubushobozi bw’urutonde rw’ivyuma bitera ijwi ry’ikibiriti risubiza inyuma uguhinduka kw’incuro zitari ku murongo z’ivyuma bitera ijwi. Ubu buryo bwo gusubiza inyuma burashobora gushika ku ntumbero nziza cane ya ±0.5 ppm ariko bushobora kuba bufise aho bugarukira mu bikorwa bikora munsi ya 3V.
Impinduka idatomoye y’Ibarabara: Yongerako igihinduzi c’ibarabara-ku -ibarabara (A/D) n’igihinduzi c’ibarabara-ku-ibarabara (D/A) inyuma y’umurongo w’uguhindura ubushuhe-ku-umuriro mu gutegura ibarabara ry’ibarabara. Ico kimenyetso kiva ku gikoresho co gupima ubushuhe gihindurwa kikaba ikimenyetso c’umubare n’umuhinduzi wa A/D, hanyuma kigasubira mu kimenyetso c’umubare n’umuhinduzi wa D/A, hanyuma kigaca kijana diode ya varactor biciye mu nzira ihuye. Ubwo buryo buratuma ubushuhe bushobora gusubirwamwo, ivyo bikaba bituma habaho ugushikama kw’incuro nyinshi cane ku gikoresho co guhindura amabuye y’agaciro. Ariko rero, urugendo rwo gutanga indishi ruragoye cane kandi rurazimvye.
TCXO
TCXOs z’ubuhinga bwa none zikoresha ubuhinga bwo gutunganya ibimenyetso vy’ubuhinga bwa none kugira ngo zibone ubushuhe bubereye. Bishiramwo igikoresho co gupima ubushuhe, igihindura A/D, umurongo w’impongano y’ubuhinga bwa none, n’igihindura D/A imbere. Ivyo bihimba birakurikirana ubushuhe bwo mu karere mu gihe nyaco kandi bikahindura neza incuro z’uguhungabana hakoreshejwe ubuhinga bwa none. Ubwo buryo bwo gusubiza inyuma buratanga ivyiza nk’ugutanga indishi ataco bihinduye, kwihuta gusubiza, no gushikama neza cane, naho nyene buza ku giciro kinini cane.
