VCXO (Umuvuduko - Igenzurwa na Crystal Oscillator) Kumenyekanisha ibicuruzwa

• Incamake y'ibicuruzwa

Umuvuduko - Igenzurwa na Crystal Oscillator (VCXO) ni ubwoko bwa kristu oscillator ihindura inshuro zayo isohoka muguhindura voltage yo hanze. Ugereranije ihindagurika ryinshi rya kristu oscillator hamwe noguhindura inshuro, VCXOs zikoreshwa cyane mubisabwa bisaba kugenzura neza neza.

VCXOs ikoresha quartz kristal nkibintu byumvikana, itanga Q - ikintu kinini kugirango ibintu bisohore neza. Mugutangiza imbaraga za voltage, VCXO irashobora guca - guhuza inshuro zayo murwego ruto, bigatuma biba byiza mugihe cyo guhuza amasaha no guhindura ibimenyetso.

• Ihame ry'akazi

Ibice bigize ibice bya VCXO birimo kristal ya quartz hamwe numuzunguruko wa oscillator. Iyo igenzura rya voltage rihindutse, ubushobozi bwa diode ya varactor burahinduka, bigahindura ubushobozi bwuzuye bwumuzunguruko wa oscillator. Uku guhindagurika mubushobozi bitera guhinduka gake mumirongo yinyeganyeza. Igenzura ryinshi rya voltage bivamo gutandukana kwinshi. Nubwo urwego ruringaniza rugufi, birahagije kurwego rwo hejuru -.

• Ibintu by'ingenzi:

1.Uburebure bukomeye: VCXOs ifata kristu ya quartz kugirango itange inshuro zidasanzwe zihamye, nibyiza kumasaha yuzuye na sisitemu yo guhuza.

2. Guhindura inshuro: Ibisohoka inshuro zishobora kuba nziza - zahujwe mugihe cyagenwe (mubisanzwe ppm nkeya kugeza kuri mirongo ppm) ukoresheje kugenzura imbaraga za voltage.

3.Ureke urusaku rw'icyiciro.

4, Ubushyuhe buhebuje: VCXOs igumana ubunyangamugayo buhamye kandi butajegajega hejuru yubushyuhe bwagutse (-40 dogere ~ +85 dogere), ibereye ibidukikije bikora nabi.

• Porogaramu

1. Sisitemu y'itumanaho.

2.Ibikoresho bikora.

3.Audio/Ibikoresho bya Video: Muri sisitemu yo hejuru - sisitemu yo gutunganya amajwi n'amashusho, VCXOs itanga ibimenyetso bike - jitter yisaha kugirango ikomeze guhuza no kuzamura ireme ryimikino.

4.Ibizamini & Ibipimo byo gupima: Nibyingenzi kuri comptabilite yumurongo, ibyuma bitanga ibimenyetso nibikoresho byipimisha neza, bigafasha kubyara neza no guhuza.

5.Satelite & Sisitemu yo kuyobora: Hejuru - guhuza neza bituma VCXOs iba nziza kuri GPS hamwe na sisitemu yitumanaho rya satelite kugirango igenzure neza.

• Ibicuruzwa byihariye

Urutonde rwinshuro: 1.25 MHz kugeza 1500 MHz (icyitegererezo - biterwa)

Urwego rwo Kuringaniza Inshuro: ± 50 ppm kugeza ± 100 ppm

Igenzura rya voltage: 0V kugeza 5V (biratandukanye ukurikije igishushanyo)

Gukoresha Ubushyuhe: -40 dogere kugeza +85 impamyabumenyi

Urusaku rw'icyiciro: -135 dBc / Hz @ 1kHz offset @ 50MHz

Tanga Umuvuduko: 1.8V / 2.5V / 3.3V / 5.0V

• Umwanzuro

Hamwe nimikorere idasanzwe kandi ihindagurika, VCXOs igira uruhare runini mubitumanaho bigezweho, guhuza imiyoboro, amajwi / videwo, hamwe no gupima no gupima. Guhindura imbaraga za voltage itanga igisubizo cyiza kuri sisitemu isaba guhinduranya inshuro. Haba mubihe by'ubushyuhe bukabije cyangwa hejuru - ibintu bisobanutse neza, VCXOs itanga imikorere isumba iyindi.

Kumanika bitanga ibicuruzwa bya VCXO mubipaki bitandukanye, hamwe nurusaku rwo hasi hamwe nubwoko bwinshi busohoka (CMOS, LVDS, LVPECL).
