Intshayelelo kwi-Type-C Connectors
USB Type-Ciye yavela njengomdlali obalaseleyo kwimarike ngenxa yeenzuzo zayo zokudibanisa kwaye ngoku isendleleni yokufikelela phezulu. Ukusetyenziswa kwayo kwiinkalo ezahlukeneyo akuthinteki. IMacBook kaApple yenze abantu bakubona lula ujongano lwe-USB Type-C kwaye iveze nendlela yophuhliso lwezixhobo ezizayo. Kwiintsuku ezizayo, ngakumbi nangakumbi izixhobo ze-USB Type-C ziya kusungulwa. Ngaphandle kwamathandabuzo, i-interface ye-USB Type-C iya kuthi ngokuthe ngcembe isasazeke kwaye ilawule imarike kwiminyaka embalwa ezayo. Ngaphezu koko, kwizixhobo eziphathwayo ezifana neefowuni kunye neetafile, zineempawu ezininzi ezenza ukuba utshaje ngokukhawuleza, isantya esiphezulu sokudlulisa idatha, kunye nenkxaso yokukhupha umboniso. Ifanelekile ngakumbi njengojongano lwemveliso yezixhobo eziphathwayo. Okona kubaluleke kakhulu, kukho imfuno eyomeleleyo yojongano lwendalo yonke ukomeleza unxibelelwano phakathi kwezixhobo ezahlukeneyo. Ezi mpawu zinokwenza ujongano lwe-Type-C lube lujongano oludityanisiweyo lwekamva, hayi kumhlaba wesicelo owubonayo!
Ukuba iyilwe ngokuhambelana nemigangatho yoshishino yoMbutho we-USB, isidibanisi se-USB Type-C sibopheleleka ukuba sibe sefashonini, sibhityile, sicuthene, silungele izixhobo eziphathwayo. Ngexesha elifanayo, kufuneka lihlangabezane neemfuno eziphezulu zamandla ombutho kwaye zifaneleke kwizicelo ezahlukeneyo zoshishino. Isidibanisi se-USB Type-C sibonelela nge-interface yeplagi ebuyiselwa umva; i-socket inokufakwa kuyo nayiphi na indlela, ukufezekisa uxhumano olulula noluthembekileyo. Esi sidibanisi sikwafuna ukuxhasa iiprothokholi ezininzi ezahlukeneyo kwaye sinokubuyela ngasemva ehambelana ne-HDMI, i-VGA, i-DisplayPort, kunye nezinye iintlobo zoqhagamshelo ukusuka kwi-C-type enye ye-USB port ngokusebenzisa iadaptha. Ukujongana nokusebenza kuphazamiseko lwe-electromagnetic (EMI) kunye nezinye iimeko ezingqongileyo ezirhabaxa, ingqwalasela yoyilo ngakumbi iyafuneka. Kucetyiswa ukuba abavelisi bakhethe abanikezeli bekhonkco abanesatifikethi se-TID ukuphepha iingxaki kwizicelo ze-terminal!
IUSB Type-C 3.1ujongano luneenzuzo ezintandathu eziphambili:
1) Ukusebenza ngokupheleleyo: Ixhasa idatha, iaudio, ividiyo, kunye nokutshaja ngaxeshanye, ukubeka isiseko sedatha yesantya esiphezulu, iaudio yedijithali, ividiyo enenkcazo ephezulu, ukutshaja ngokukhawuleza, kunye nokwabelana ngezixhobo ezininzi. Intambo enye inokubuyisela iintambo ezininzi ezisetyenziswe ngaphambili.
2) Ukufakela ukuguqulwa: Ngokufana ne-Apple Lightning interface, i-front and back of the port iyafana, ixhasa ukufakwa ukuguqulwa.
I-3) Ukuhanjiswa kwe-Bidirectional: Idatha kunye namandla anokudluliselwa kuwo omabini amacala.
I-4) Ukuhambelana ngasemva: Ngokusebenzisa iadaptha, inokuhambelana ne-USB Type-A, Micro-B, kunye nolunye ujongano.
5) Ubungakanani obuncinci: Ubungakanani be-interface yi-8.3mm x 2.5mm, malunga nesinye kwisithathu sobungakanani be-interface ye-USB-A.
6) Isantya esiphezulu: Iyahambelana neI-USB 3.1protocol, inokuxhasa ukuya kuthi ga kwi-10Gb / s ukuhanjiswa kwedatha, njengayeI-USB C 10GbpskwayeUSB 3.1 Gen 2imigangatho, ukufikelela usulelo olukhawuleza kakhulu.
Imiyalelo yoNxibelelwano lwe-USB PD
I-USB - Ukuhanjiswa kwamandla (i-USB PD) yinkcazo yeprotocol eyenza ukuhanjiswa kwangaxeshanye ukuya kuthi ga kwi-100W yamandla kunye nonxibelelwano lwedatha kwintambo enye; I-USB Type-C yinkcazo entsha ngokupheleleyo yokudibanisa i-USB enokuxhasa uluhlu lwemigangatho emitsha efana ne-USB 3.1 (Gen1 kunye ne-Gen2), i-Display Port, kunye ne-USB PD; amandla ombane aphezulu amiselweyo kunye akhoyo kwizibuko le-USB Type-C yi-5V 3A; ukuba i-USB PD iphunyeziwe kwi-USB Type-C port, inokuxhasa amandla e-240W achazwe kwinkcazo ye-USB PD, ngoko ke, ukuba ne-USB Type-C port akuthethi ukuba ixhasa i-USB PD; I-USB PD ibonakala iyiprothokholi yokuhanjiswa kwamandla kunye nolawulo, kodwa ngokwenene, inokutshintsha iindima zezibuko, inxibelelane neentambo ezisebenzayo, ivumele i-DFP ibe sisixhobo sonikezelo lwamandla kunye neminye imisebenzi emininzi ephezulu. Ngoko ke, izixhobo ezixhasa iPD kufuneka zisebenzise i-CC Logic chips (ii-chips ze-E-Mark), umzekelo, usebenzisa i-5A 100W USB C Cableinokufezekisa unikezelo lwamandla olusebenzayo.
I-USB Type-C VBUS Ukufunyanwa kwangoku kunye nokusetyenziswa
I-USB Type-C yongeze ubhaqo lwangoku kunye nokusetyenziswa kwemisebenzi. Iimowudi ezintathu zangoku ezintsha ziye zaziswa: imowudi yamandla ye-USB engagqibekanga (500mA/900mA), 1.5A, kunye ne-3.0A. Ezi ndlela zintathu zangoku zihanjiswa kwaye zichongiwe ngeephini zeCC. Kwii-DFPs ezifuna isakhono semveliso yosasazo yangoku, amaxabiso ahlukeneyo e-CC pull-up resistors Rp ayafuneka ukufezekisa oku. Kwii-UFPs, ixabiso le-voltage kwiphini ye-CC kufuneka lichongwe ukuze lifumane amandla okukhutshwa kwangoku kwenye i-DFP.
I-DFP-to-UFP kunye noLawulo lwe-VBUS kunye nokuFumana
I-DFP yi-USB Type-C port ebekwe kumamkeli okanye i-hub, eqhagamshelwe kwisixhobo. I-UFP yi-USB Type-C port ebekwe kwisixhobo okanye kwi-hub, eqhagamshelwe kumamkeli okanye i-hub's DFP. I-DRP yi-USB Type-C port enokusebenza njenge-DFP okanye i-UFP. I-DRP itshintsha phakathi kwe-DFP kunye ne-UFP yonke i-50ms kwimodi yokulinda. Xa utshintshela kwi-DFP, kufuneka kubekho i-resistor Rp edonsa ukuya kwi-VBUS okanye imveliso yangoku yomthombo kwi-pin ye-CC. Xa utshintshela kwi-UFP, kufuneka kubekho i-resistor Rd edonsa phantsi kwi-GND kwiphini ye-CC. Eli nyathelo lokutshintsha kufuneka ligqitywe yi-CC Logic chip.
I-VBUS inokukhutshwa kuphela xa i-DFP ibona ukufakwa kwe-UFP. Nje ukuba i-UFP isusiwe, i-VBUS kufuneka icinywe. Lo msebenzi kufuneka ugqitywe yi-CC Logic chip.
Qaphela: Le DRP ikhankanywe ngasentla yahlukile kwi-USB-PD DRP. I-USB-PD DRP ibhekisela kumazibuko ombane asebenza njengoMthombo waMandla (umboneleli) kunye neSinki (umthengi), umzekelo, i-USB Type-C port kwi-laptop isekela i-USB-PD DRP, enokuthi isebenze njengoMthombo waMandla (xa udibanisa i-USB drive okanye ifowuni yeselula) okanye iSinki (xa udibanisa imonitha okanye i-adapter yamandla).
Ingcamango ye-DRP, ingcamango ye-DFP, ingcamango ye-UFP
Ukuhanjiswa kwedatha ubukhulu becala kuqulathe iiseti ezimbini zemiqondiso eyahlukileyo, TX/RX. I-CC1 kunye ne-CC2 zizikhonkwane ezibini eziphambili ezinemisebenzi emininzi:
Ukubona uxhulumaniso, ukwahlula phakathi kwamacala angaphambili nangasemva, ukwahlula phakathi kwe-DFP kunye ne-UFP, eyi-master-slave configuration ye-Vbus, kukho iindidi ezimbini ze-USB Type-C kunye ne-USB Power Delivery.
Ukuqwalasela iVconn. Xa kukho i-chip kwikhebula, enye iCC idlulisela umqondiso, kwaye enye iCC iba ngumbane weVconn. Ukuqwalasela ezinye iindlela, njengaxa udibanisa izixhobo zomsindo, i-DP, i-PCIE, kukho amandla amane kunye nemigca yomhlaba ngamnye, i-DRP (i-Dual Role Port): i-port yendima ye-dual, i-DRP ingasetyenziswa njenge-DFP (I-Host), i-UFP (Isixhobo), okanye i-dynamically switch phakathi kwe-DFP kunye ne-UFP. Isixhobo esiqhelekileyo se-DRP yikhompyuter (ikhompyuter inokusebenza njengenginginya ye-USB okanye isixhobo esiya kuhlawuliswa (iMacBook Air entsha ye-Apple)), ifowuni ephathwayo enomsebenzi we-OTG (ifowuni ephathwayo inokusebenza njengesixhobo ekufuneka ihlawulwe kwaye ifunde idatha, okanye njengenginginya ukunika amandla okanye ukufunda idatha esuka kwi-USB drive), ibhanki yamandla (ukukhutshwa kunye nokutshaja kunokwenziwa nge-USB Type-C enye, ukukhupha i-USB Type-C).
Umxhasi oqhelekileyo womxhasi (DFP-UFP) uphumezo indlela ye-USB Type-C
Ingcamango yeCCpin
I-CC (Ishaneli yoLungiso): Ishaneli yoqwalaselo, le tshaneli entsha eyongeziweyo engundoqo kwi-USB Type-C. Imisebenzi yayo ibandakanya ukufumanisa uxhulumaniso lwe-USB, ukufumanisa isalathiso esichanekileyo sokufaka, ukuseka nokulawula uxhulumaniso phakathi kwezixhobo ze-USB kunye neVBUS, njl.
Kukho i-high pull-up resistor Rp kwi-CC pin ye-DFP, kunye ne-down pull-down resistor Rd kwi-UFP. Xa ingaxhunyiwe, i-VBUS ye-DFP ayinayo imveliso. Emva kokudibanisa, i-pin ye-CC ixhunyiwe, kwaye i-CC pin ye-DFP iya kubona i-pull-down resistor Rd ye-UFP, ebonisa ukuba uxhumano lwenziwa. Emva koko, i-DFP iya kuvula umbane weVbus kunye negunya lokuphuma kwi-UFP. Yeyiphi i-CC pin (CC1, CC2) ebona i-resistor yokutsalela-phantsi imisela indlela yokufaka ujongano, kwaye iphinde itshintshe i-RX/TX. Ukuxhathisa i-Rd = 5.1k, kunye nokumelana ne-Rp lixabiso elingaqinisekanga. Ngokomzobo wangaphambili, kunokubonwa ukuba kukho iindlela ezininzi zobonelelo lwamandla kwi-USB Type-C. Indlela yokwahlula? Isekelwe kwixabiso le-Rp. I-voltage efunyenwe yi-CC pin ihluke xa ixabiso le-Rp lihlukile, kwaye emva koko ulawule ukuphela kwe-DFP ukwenza ukuba yeyiphi imo yonikezelo lwamandla. Kufuneka kuqatshelwe ukuba izikhonkwane ezimbini zeCC zizotyiweyo kulo mzobo ungentla eneneni ngumgca omnye weCC kuphela kwintambo ngaphandle kwechip.
