Intangiriro Kuri Type-C Ihuza
USB Ubwoko-Cyagaragaye nkumukinnyi wiganje ku isoko bitewe ninyungu zayo zihuza none iri hafi kugera hejuru. Porogaramu yayo mubice bitandukanye ntabwo ihagarikwa. MacBook ya Apple yatumye abantu bamenya ubworoherane bwa USB Type-C kandi inagaragaza iterambere ryibikoresho bizaza. Mu minsi iri imbere, ibikoresho byinshi bya USB Type-C bizashyirwa ahagaragara. Nta gushidikanya, interineti ya USB Type-C izagenda ikwirakwira buhoro buhoro kandi yiganje ku isoko mu myaka mike iri imbere. Byongeye kandi, kubikoresho bigendanwa nka terefone na tableti, bifite ibintu byinshi bifasha kwishyuza byihuse, umuvuduko wo kohereza amakuru byihuse, hamwe no gushyigikira ibyasohotse. Birakwiriye cyane nkibisohoka mubikoresho bigendanwa. Icyingenzi cyane, harakenewe cyane intera rusange kugirango yongere umubano hagati yibikoresho bitandukanye. Ibiranga birashobora gutuma Ubwoko-C bugaragara rwose bigahinduka intera ihuriweho nigihe kizaza, ntabwo ari murwego rwo gusaba gusa!
Niba yarakozwe hakurikijwe amahame yinganda zishyirahamwe rya USB, umuhuza wa USB Type-C ugomba kuba moda, yoroheje, kandi yoroheje, ikwiranye nibikoresho bigendanwa. Muri icyo gihe, igomba kuba yujuje imbaraga nyinshi zisabwa n’ishyirahamwe kandi ikwiriye gukoreshwa mu nganda zitandukanye. USB Type-C ihuza itanga interineti isubira inyuma; sock irashobora kwinjizwa mubyerekezo byose, kugera kubintu byoroshye kandi byizewe. Uyu muhuza akeneye kandi gushyigikira protocole nyinshi zitandukanye kandi irashobora gusubira inyuma igahuzwa na HDMI, VGA, DisplayPort, nubundi bwoko bwihuza buva kumurongo umwe wo mu bwoko bwa C bwa USB ukoresheje adapteri. Kugira ngo ukemure imikorere muri electromagnetic intervention (EMI) nibindi bidukikije bikaze, harakenewe ibindi bitekerezo. Birasabwa ko abayikora bahitamo abatanga umuhuza bafite icyemezo cya TID kugirango birinde ibibazo mubikorwa bya terefone!
UwitekaUSB Ubwoko-C 3.1Imigaragarire ifite ibyiza bitandatu byingenzi:
1) Imikorere yuzuye: Ifasha amakuru, amajwi, videwo, hamwe no kwishyuza icyarimwe, ishyiraho urufatiro rwamakuru yihuta, amajwi ya digitale, videwo isobanura cyane, kwishyuza byihuse, no kugabana ibikoresho byinshi. Umugozi umwe urashobora gusimbuza insinga nyinshi zikoreshwa mbere.
2) Kwinjiza ibintu bidasubirwaho: Bisa na Interineti ya Lightning, imbere ninyuma yicyambu ni kimwe, gishyigikira kwinjiza.
3) Ihererekanyabubasha: Amakuru n'imbaraga birashobora koherezwa mubyerekezo byombi.
4) Guhuza inyuma: Binyuze muri adapt, birashobora guhuzwa na USB Type-A, Micro-B, nibindi bice.
5) Ingano nto: Ingano yimbere ni 8.3mm x 2,5mm, hafi kimwe cya gatatu cy'ubunini bwa USB-A.
6) Umuvuduko mwinshi: Bihujwe naUSB 3.1protocole, irashobora gushyigikira kugeza 10Gb / s amakuru yoherejwe, nkaUSB C 10GbpsnaUSB 3.1 Itang 2ibipimo, kugera kuri ultra-yihuta yohereza.
Amabwiriza ya USB PD
USB - Gutanga amashanyarazi (USB PD) ni protocole isobanura ituma icyarimwe cyohereza icyarimwe kugeza kuri 100W yingufu nogutumanaho amakuru kumurongo umwe; USB Type-C ni ibisobanuro bishya rwose kubihuza USB ishobora gushyigikira urukurikirane rwibipimo bishya nka USB 3.1 (Gen1 na Gen2), Icyerekezo cyerekana, na USB PD; isanzwe ntarengwa ishyigikiwe na voltage nubu kuri USB Type-C icyambu ni 5V 3A; niba USB PD ishyizwe mubikorwa icyambu cya USB Type-C, irashobora gushyigikira ingufu za 240W zasobanuwe mubisobanuro bya USB PD, kubwibyo, kugira icyambu cya USB Type-C ntabwo bivuze ko ishyigikiye USB PD; USB PD isa nkaho ari protocole gusa yo kohereza amashanyarazi no kuyobora, ariko mubyukuri, irashobora guhindura inshingano zicyambu, kuvugana ninsinga zikora, kwemerera DFP kuba igikoresho cyo gutanga amashanyarazi nibindi bikorwa byinshi byateye imbere. Kubwibyo, ibikoresho bishyigikira PD bigomba gukoresha CC Logic chips (E-Mark chips), kurugero, ukoresheje a5A 100W USB C Umugoziirashobora kugera ku mashanyarazi meza.
USB Ubwoko-C VBUS Kumenyekanisha no Gukoresha
USB Type-C yongeyeho ibikorwa byo gutahura no gukoresha. Uburyo butatu bushya bwatangijwe: uburyo bwa USB busanzwe (500mA / 900mA), 1.5A, na 3.0A. Ubu buryo butatu bwoherejwe kandi bugaragazwa binyuze muri pine ya CC. Kuri DFPs isaba gutangaza ubushobozi bwibisohoka, indangagaciro zitandukanye za CC gukurura ristors Rp irakenewe kugirango ibi bigerweho. Kuri UFP, agaciro ka voltage kuri CC pin igomba gutahurwa kugirango ubone ubushobozi bwibisohoka byubu bya DFP.
DFP-kuri-UFP na VBUS Ubuyobozi no Kumenya
DFP ni icyambu cya USB Type-C giherereye kuri host cyangwa hub, ihujwe nigikoresho. UFP ni icyambu cya USB Type-C giherereye ku gikoresho cyangwa hub, gihujwe na host cyangwa DFP ya hub. DRP ni icyambu cya USB Type-C gishobora gukora nka DFP cyangwa UFP. DRP ihinduranya hagati ya DFP na UFP buri 50m muburyo bwo guhagarara. Iyo uhinduye kuri DFP, hagomba kubaho ristoriste Rp ikurura VBUS cyangwa isoko yasohotse kuri pin ya CC. Iyo uhinduye kuri UFP, hagomba kubaho ristoriste Rd ikamanuka kuri GND kuri pin ya CC. Iki gikorwa cyo guhinduranya kigomba kurangizwa na CC Logic chip.
VBUS irashobora gusohoka gusa mugihe DFP ibonye kwinjiza UFP. UFP imaze kuvaho, VBUS igomba kuzimwa. Iki gikorwa kigomba kurangizwa na chip Logic chip.
Icyitonderwa: DRP yavuzwe haruguru itandukanye na USB-PD DRP. USB-PD DRP bivuga ibyambu byamashanyarazi bikora nka Power Source (itanga) na Sink (umuguzi), kurugero, icyambu cya USB Type-C kuri mudasobwa igendanwa gishyigikira USB-PD DRP, gishobora gukora nka Power Source (mugihe uhuza USB cyangwa telefone igendanwa) cyangwa Sink (mugihe uhuza monitor cyangwa adaptateur power).
Igitekerezo cya DRP, igitekerezo cya DFP, igitekerezo cya UFP
Kohereza amakuru bigizwe ahanini nibice bibiri byerekana ibimenyetso bitandukanye, TX / RX. CC1 na CC2 ni pin ebyiri zingenzi zifite imirimo myinshi:
Gutahura amasano, gutandukanya impande zinyuma ninyuma, gutandukanya DFP na UFP, aribwo buryo bwa shebuja-imbata ya Vbus, hari ubwoko bubiri bwa USB Type-C na USB Power Delivery.
Kugena Vconn. Iyo hari chip mu mugozi, CC imwe itanga ikimenyetso, indi CC ihinduka amashanyarazi Vconn. Kugena ubundi buryo, nkigihe uhuza ibikoresho byamajwi, DP, PCIE, hariho imbaraga enye numurongo wubutaka kuri buri, DRP (Uruhare rwibikorwa bibiri): icyambu cyibikorwa bibiri, DRP irashobora gukoreshwa nka DFP (Host), UFP (Igikoresho), cyangwa guhinduranya hagati ya DFP na UFP. Igikoresho gisanzwe cya DRP ni mudasobwa (mudasobwa irashobora gukora nka USB yakira cyangwa igikoresho cyo kwishyurwa (Apple nshya ya MacBook Air ya Apple)), terefone igendanwa ifite imikorere ya OTG (terefone igendanwa irashobora gukora nk'igikoresho cyo kwishyurwa no gusoma amakuru, cyangwa nk'uwakiriye gutanga ingufu cyangwa gusoma amakuru ava muri USB Drive), banki y'amashanyarazi (gusohora no kwishyuza birashobora gukorwa binyuze kuri USB Type-C, kandi ni,)
Ubusanzwe host-umukiriya (DFP-UFP) uburyo bwo gushyira mubikorwa USB Type-C
CCpin
CC (Umuyoboro Iboneza): Umuyoboro Iboneza, uyu ni umuyoboro mushya wongeyeho muri USB Type-C. Mubikorwa byayo harimo kumenya USB ihuza, kumenya icyerekezo cyinjiza neza, gushiraho no gucunga isano iri hagati yibikoresho bya USB na VBUS, nibindi.
Hano harikururwa hejuru-ristoriste Rp kuri CC pin ya DFP, hamwe na rezistor yo hepfo Rd kuri UFP. Iyo idahujwe, VBUS ya DFP nta bisohoka. Nyuma yo guhuza, pin ya CC irahujwe, kandi CC pin ya DFP izamenya gukurura-gukuramo Rd ya UFP, byerekana ko ihuza ryakozwe. Hanyuma, DFP izakingura ingufu za Vbus nimbaraga zisohoka muri UFP. Nibihe CC pin (CC1, CC2) itahura rezistor ikurura igena icyerekezo cyo kwinjiza intera, kandi ikanahindura RX / TX. Kurwanya Rd = 5.1k, naho kurwanya Rp nigiciro kitazwi. Ukurikije igishushanyo kibanziriza iki, birashobora kugaragara ko hari uburyo bwinshi bwo gutanga amashanyarazi kuri USB Type-C. Nigute wabatandukanya? Ishingiye ku gaciro ka Rp. Umuvuduko wagaragajwe na CC pin uratandukanye mugihe agaciro ka Rp gatandukanye, hanyuma ukagenzura amaherezo ya DFP kugirango ukore uburyo bwo gutanga amashanyarazi. Twabibutsa ko pin ebyiri za CC zishushanyije mumashusho yavuzwe haruguru mubyukuri umurongo umwe wa CC mumurongo udafite chip.
