Intshayelelo kwii-Connectors ze-Type-C
Uhlobo lwe-C lwe-USBIvele njengomdlali obalaseleyo kwimarike ngenxa yeenzuzo zayo zokudibanisa kwaye ngoku ikufutshane nokufikelela phezulu. Ukusetyenziswa kwayo kwiindawo ezahlukeneyo akunakuthintelwa. I-MacBook ye-Apple yenze abantu baqaphele ukulula kojongano lwe-USB Type-C kwaye ikwatyhile nendlela yophuhliso lwezixhobo zexesha elizayo. Kwimihla ezayo, izixhobo ezininzi ze-USB Type-C ziya kuqaliswa. Ngokungathandabuzekiyo, ujongano lwe-USB Type-C luya kusasazeka kancinci kwaye lulawule imarike kwiminyaka embalwa ezayo. Ngaphezu koko, kwizixhobo eziphathwayo ezifana neefowuni kunye neethebhulethi, ineempawu ezininzi ezivumela ukutshaja ngokukhawuleza, isantya esiphezulu sokudlulisa idatha, kunye nenkxaso yokukhupha isibonisi. Ifanelekile ngakumbi njengojongano lokukhupha kwizixhobo eziphathwayo. Okubaluleke kakhulu, kukho imfuneko enkulu yojongano lwehlabathi lonke ukuphucula unxibelelwano phakathi kwezixhobo ezahlukeneyo. Ezi mpawu zinokwenza ujongano lwe-Type-C lube ngujongano oludibeneyo lwexesha elizayo, kungekuphela nje kwiindawo zesicelo ozibonayo!
Ukuba yenzelwe ngokwemigangatho yoshishino lwe-USB Association, isixhumi se-USB Type-C siya kuba sefashonini, sincinci, kwaye sincinci, sifanele izixhobo eziphathwayo. Kwangaxeshanye, kufuneka sihlangabezane neemfuno ezinamandla aphezulu zombutho kwaye sifaneleke kwiintlobo ngeentlobo zezicelo zoshishino. Isixhumi se-USB Type-C sinika ujongano lweplagi oluguqukayo; isokhethi ingafakwa nakweyiphi na indlela, nto leyo eyenza kube lula kwaye kuthembeke unxibelelwano. Esi sixhumi kufuneka sixhase iiprotokholi ezahlukeneyo kwaye sinokuhambelana ngasemva ne-HDMI, i-VGA, i-DisplayPort, kunye nezinye iintlobo zonxibelelwano ukusuka kwi-USB port enye ye-C-type ngokusebenzisa ii-adapters. Ukujongana nokusebenza kwi-electromagnetic interference (EMI) kunye nezinye iindawo ezinzima, kufuneka kuqwalaselwe ngakumbi uyilo. Kucetyiswa ukuba abavelisi bakhethe ababoneleli besixhumi abanesatifikethi se-TID ukuze baphephe iingxaki kwiizicelo zesiphelo!
IUhlobo lwe-USB C 3.1Ujongano luneengenelo ezintandathu eziphambili:
1) Ukusebenza okugcweleyo: Ixhasa idatha, iaudio, ividiyo, kunye nokutshaja ngaxeshanye, ibeka isiseko sedatha ekhawulezayo, iaudio yedijithali, ividiyo ecacileyo, ukutshaja ngokukhawuleza, kunye nokwabelana ngezixhobo ezininzi. Intambo enye inokutshintsha iintambo ezininzi ezazisetyenziswa ngaphambili.
2) Ukufakwa okunokuguqulwa: Ngokufana ne-Apple Lightning interface, umphambili nomva we-port ziyafana, zixhasa ukufakwa okunokuguqulwa.
3) Uthumelo lwendlela ezimbini: Idatha kunye namandla zinokudluliselwa kuzo zombini iindlela.
4) Ukuhambelana ngasemva: Ngee-adaptha, ingahambelana ne-USB Type-A, Micro-B, kunye nezinye iindlela zokunxibelelana.
5) Ubungakanani obuncinci: Ubungakanani be-interface yi-8.3mm x 2.5mm, malunga nesinye kwisithathu sobukhulu be-interface ye-USB-A.
6) Isantya esiphezulu: IyahambelanaI-USB 3.1iprotokholi, inokuxhasa ukuhanjiswa kwedatha ukuya kuthi ga kwi-10Gb/s, efanaI-USB C 10GbpskwayeI-USB 3.1 Gen 2imigangatho, ukufikelela kuthumelo olukhawulezayo kakhulu.
Imiyalelo yoNxibelelwano lwe-USB PD
I-USB - Ukuhanjiswa kwamandla (i-USB PD) yinkcazo yeprotocol evumela ukuhanjiswa ngaxeshanye ukuya kuthi ga kwi-100W yamandla kunye nonxibelelwano lwedatha ngentambo enye; I-USB Type-C yinkcazo entsha ngokupheleleyo yesixhumi se-USB esinokuxhasa uthotho lwemigangatho emitsha efana ne-USB 3.1 (Gen1 kunye neGen2), iDisplay Port, kunye ne-USB PD; i-voltage ephezulu exhaswayo kunye nomsinga we-USB Type-C port yi-5V 3A; ukuba i-USB PD isetyenziswa kwi-USB Type-C port, inokuxhasa amandla angama-240W achazwe kwinkcazo ye-USB PD, ngoko ke, ukuba ne-USB Type-C port akuthethi ukuba ixhasa i-USB PD; I-USB PD ibonakala ngathi yinkqubo nje yokudlulisela amandla kunye nolawulo, kodwa eneneni, inokutshintsha iindima zezibuko, inxibelelane neentambo ezisebenzayo, ivumele i-DFP ukuba ibe sisixhobo sokubonelela ngombane kunye neminye imisebenzi emininzi ephambili. Ke ngoko, izixhobo ezixhasa i-PD kufuneka zisebenzise ii-CC Logic chips (ii-E-Mark chips), umzekelo, ukusebenzisa iIntambo ye-USB C ye-5A eyi-100Wingafikelela ekunikezelweni kombane ngokufanelekileyo.
Ukufunyanwa nokusetyenziswa kweVBUS yohlobo C lwe-USB
Uhlobo lwe-USB C longeze imisebenzi yokufumanisa nokusetyenziswa kwangoku. Iindlela ezintathu ezintsha zangoku ziye zaziswa: imo yamandla e-USB emiselweyo (500mA/900mA), 1.5A, kunye ne-3.0A. Ezi ndlela zintathu zangoku ziyadluliselwa kwaye zifunyanwe ngee-CC pin. Kwii-DFP ezifuna amandla okukhupha amandla okusasaza, amaxabiso ahlukeneyo e-CC pull-up resistors Rp ayafuneka ukuze kufezekiswe oku. Kwii-UFP, ixabiso le-voltage kwi-CC pin kufuneka lifunyanwe ukuze kufumaneke amandla okukhupha amandla angoku kwenye i-DFP.
Ulawulo kunye nokuFunyanwa kwe-DFP-to-UFP kunye ne-VBUS
I-DFP sisibuko se-USB Type-C esikwi-host okanye kwi-hub, esiqhagamshelwe kwisixhobo. I-UFP sisibuko se-USB Type-C esikwisixhobo okanye kwi-hub, esiqhagamshelwe kwi-DFP ye-host okanye ye-hub. I-DRP sisibuko se-USB Type-C esinokusebenza njenge-DFP okanye i-UFP. I-DRP itshintsha phakathi kwe-DFP kunye ne-UFP rhoqo emva kwe-50ms kwimo yokulinda. Xa utshintshela kwi-DFP, kufuneka kubekho i-resistor Rp etsala isiya kwi-VBUS okanye i-current source output kwi-CC pin. Xa utshintshela kwi-UFP, kufuneka kubekho i-resistor Rd etsala isiya kwi-GND kwi-CC pin. Esi senzo sokutshintsha kufuneka sigqitywe 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: I-DRP ekhankanyiweyo apha ngasentla yahlukile kwi-USB-PD DRP. I-USB-PD DRP ibhekisa kwiipoti zamandla ezisebenza njengoMthombo wamandla (umboneleli) kunye neSink (umthengi), umzekelo, ipoti ye-USB Type-C kwilaptop ixhasa i-USB-PD DRP, enokusebenza njengoMthombo wamandla (xa uqhagamshela i-USB drive okanye ifowuni ephathwayo) okanye iSink (xa uqhagamshela imonitha okanye iadaptha yamandla).
Ingcamango ye-DRP, ingqiqo ye-DFP, ingqiqo ye-UFP
Ukuhanjiswa kwedatha ikakhulu kuqulathe iiseti ezimbini zeempawu zomahluko, i-TX/RX. I-CC1 kunye ne-CC2 zii-key pin ezimbini ezinemisebenzi emininzi:
Ukufumanisa uqhagamshelo, ukwahlula phakathi kwamacala angaphambili nangasemva, ukwahlula phakathi kwe-DFP kunye ne-UFP, oluyilungiselelo le-master-slave ye-Vbus, kukho iintlobo ezimbini ze-USB Type-C kunye ne-USB Power Delivery.
Ukumisela i-Vconn. Xa kukho itshiphu kwintambo, i-CC enye idlulisela isignali, kwaye enye i-CC iba yi-Vconn yombane. Ukumisela ezinye iindlela, ezinje xa uqhagamshela izixhobo zesandi, i-DP, i-PCIE, kukho imigca emine yamandla kunye nomhlaba nganye, i-DRP (iDual Role Port): i-dual-role port, i-DRP ingasetyenziswa njenge-DFP (Host), i-UFP (Device), okanye itshintshe ngokuguquguqukayo phakathi kwe-DFP kunye ne-UFP. Isixhobo esiqhelekileyo se-DRP yikhompyutha (ikhompyutha ingasebenza njenge-USB host okanye isixhobo esiza kutshajwa (i-MacBook Air entsha ye-Apple)), ifowuni ephathwayo enomsebenzi we-OTG (ifowuni ephathwayo ingasebenza njengesixhobo esiza kutshajwa kwaye sifunde idatha, okanye njenge-host yokubonelela ngamandla okanye yokufunda idatha kwi-USB drive), ibhanki yamandla (ukukhupha kunye nokutshaja kungenziwa nge-USB Type-C enye, oko kukuthi, le port inokukhupha kunye nokutshaja).
Indlela eqhelekileyo yokuphumeza i-host-client (DFP-UFP) ye-USB Type-C
Ingcamango ye-CCpin
I-CC (Itshaneli yoCwangciso): Itshaneli yoCwangciso, le yitshaneli entsha eyongeziweyo kwi-USB Type-C. Imisebenzi yayo ibandakanya ukubona uqhagamshelo lwe-USB, ukubona icala elifanelekileyo lokufaka, ukuseka nokulawula uqhagamshelo phakathi kwezixhobo ze-USB kunye ne-VBUS, njl.
Kukho i-resistor yokutsala phezulu ephezulu i-Rp kwi-CC pin ye-DFP, kunye ne-resistor yokutsala esezantsi i-Rd kwi-UFP. Xa ingaqhagamshelwanga, i-VBUS ye-DFP ayinamveliso. Emva koqhagamshelo, i-CC pin iqhagamshelwe, kwaye i-CC pin ye-DFP iya kubona i-resistor yokutsala ezantsi i-Rd ye-UFP, nto leyo ebonisa ukuba uqhagamshelo lwenziwe. Emva koko, i-DFP iya kuvula iswitshi yamandla e-Vbus kunye namandla okukhupha kwi-UFP. Yeyiphi i-CC pin (CC1, CC2) ebona i-resistor yokutsala ezantsi imisela indlela yokufaka i-interface, kwaye ikwatshintsha i-RX/TX. I-resistance Rd = 5.1k, kwaye i-resistance Rp lixabiso elingaqinisekanga. Ngokwesazobe sangaphambili, kunokubonwa ukuba kukho iindlela ezininzi zombane ze-USB Type-C. Ungazihlula njani? Isekelwe kwixabiso le-Rp. I-voltage efunyenwe yi-CC pin yahlukile xa ixabiso le-Rp lahlukile, kwaye emva koko ilawula isiphelo se-DFP ukuze isebenze indlela yombane. Kufuneka kuqatshelwe ukuba ii-CC pin ezimbini ezidwetshwe kumfanekiso ongentla zingumgca omnye we-CC kwintambo ngaphandle kwetshiphu.
