Enye yezinto ezimangalisayo malunga ne-USB-C kubuchule bayo besantya esiphezulu. I-pinout ikunika izibini ezine zokwahluka kwesantya esiphezulu kunye nezibini ezahlukeneyo ezinesantya esisezantsi, ezikuvumela ukuba ukhuphele amanani amakhulu edatha ngezihlanganisi ngaphantsi kwe dime. Ayizizo zonke izixhobo ezisebenzisa eli nqaku, kwaye akufanelekanga - i-USB-C yenzelwe ukuba ifikeleleke kuzo zonke izixhobo eziphathwayo. Nangona kunjalo, xa isixhobo sakho sifuna isantya esiphezulu kwi-USB-C, uya kufumanisa ukuba i-USB-C inokukunika eso santya siphezulu kunye nendlela esebenza ngayo.
Ukukwazi ukufumana ujongano olukwisantya esiphezulu kwi-USB-C kuthiwa yiNdlela Eyenye, okanye iNdlela Eyenye ngokufutshane. Iindlela ezintathu onokuthi udibane nazo namhlanje yi-USB3, iDisplayPort, kunye neThunderbolt, ezinye sele ziphela, njenge-HDMI kunye ne-VirtualLink, kwaye ezinye ziphezulu, njenge-USB4. Uninzi lweendlela ezizezinye zifuna unxibelelwano lwedijithali lwe-USB-C usebenzisa uhlobo oluthile lomyalezo wekhonkco wePD. Nangona kunjalo, ayizizo zonke ii-USB3 ezilula kakhulu. Makhe sibone ukuba enye itemplate yenza ntoni.
Ukuba ubonile i-pinout, uzibonile izikhonkwane zesantya esiphezulu. Namhlanje ndifuna ukukubonisa ukuba yeyiphi i-interfaces ekhoyo kwezi zikhonkwane namhlanje. Olu ayiloluhlu olupheleleyo okanye olubanzi – andizukuthetha ngezinto ezifana ne-USB4, umzekelo, ngokuyinxenye kuba andazi ngokwaneleyo ngayo okanye ndinamava ngayo; kukhuselekile ukucinga ukuba siya kufumana ngakumbi izixhobo ezixhotyiswe nge-USB kwixesha elizayo -C kwizixhobo ezinesantya esiphezulu. Kwakhona, i-USB-C ibhetyebhetye ngokwaneleyo kangangokuba abaduni banokuveza i-Ethernet okanye i-SATA ngendlela ehambelana ne-USB-C ukuba yiloo nto uyifunayo, mhlawumbi olu hlaziyo lunokukunceda ukuba ufumanise.
I-USB3 ilula, ilula kakhulu - nje isibini se-TX kunye nesibini se-RX, nangona izinga lokudluliselwa liphezulu kakhulu kune-USB2, liyalawuleka kubaduni. Ukuba usebenzisa i-PCB ye-multilayer ene-USB3 yolawulo lwe-impedance yomqondiso kunye nentlonipho yezibini ezihlukeneyo, uqhagamshelwano lwakho lwe-USB3 luhlala lusebenza kakuhle.
Akukho nto ingako itshintshileyo kwi-USB3 ngaphezulu kwe-USB-C - uya kuba ne-multiplexer yokusingatha ukujikeleza, kodwa imalunga nayo. Ii-multiplexers ze-USB3 zininzi, ke ukuba wongeza i-USB-C ene-USB3 port kwi-motherboard yakho, akunakufane ube neengxaki. Kukwakho neDual Channel USB3, esebenzisa amajelo e-USB3 afanayo ukunyusa i-bandwidth, kodwa abahlaseli abadli ngokungena okanye bafune oku, kwaye i-Thunderbolt ithande ukugubungela le ndawo ngcono. Ngaba ufuna ukuguqula isixhobo se-USB3 sibe isixhobo se-USB-C? Ekuphela kwento oyifunayo yi-multiplexer. Ukuba ucinga ngokufaka i-MicroUSB 3.0 isidibanisi kwi-motherboard yakho yezixhobo zakho ezinesantya esiphezulu, ngoko ngokuzithoba kodwa ngamandla ndikucela ukuba utshintshe ingqondo yakho kwaye ufake isidibanisi se-USB-C kunye ne-VL160 kuyo.
Ukuba uyila isixhobo se-USB3 esineplagi, awufuni nokuba i-multiplexer yokusingatha ukujikeleza - enyanisweni, awudingi naluphi na ubhaqo lokujikeleza. I-resistor enye engalawulwayo ye-5.1kΩ yanele ukudala i-USB3 flash drive eplaga ngqo kwi-USB-C port, okanye ukwenza i-USB-C eyindoda ukuya kwi-adapter ye-USB-A 3.0. Ukuya kuthi ga kwisokethi, unokunqanda ukusebenzisa i-multiplexer ukuba unoqhagamshelo lwe-USB3 lwasimahla lokubingelela, leyo ayiyonto ingako. Andazi ngokwaneleyo malunga netshaneli ye-USB3 ephindwe kabini ukuqinisekisa ukuba itshaneli ye-USB3 ixhasa uqhagamshelo olunjalo, kodwa ndicinga ukuba impendulo ethi “hayi” inokubakho kuno “ewe”!
I-DisplayPort (DP) i-interface enkulu yokudibanisa i-high-resolution displays - igqithise i-HDMI kwiidesktops, ilawula indawo yokubonisa eyakhelwe-ngaphakathi ngendlela ye-eDP, kwaye ihambisa isisombululo esiphezulu kwikhebula elilodwa, ngokuphindaphindiweyo ingcono kune-HDMI. Iyakwazi ukuguqulwa kwi-DVI okanye i-HDMI isebenzisa i-adapter engabizi kakhulu esebenzisa umgangatho we-DP ++ kwaye i-royalty-free njenge-HDMI. Iyavakala into yokuba umanyano lweVESA lusebenze neqela le-USB ukuphumeza inkxaso yeDisplayPort, ngakumbi njengoko ii-DisplayPort transmitters kwii-SoCs zisiya zithandwa ngakumbi.
Ukuba usebenzisa idokhi ene-HDMI okanye i-VGA ephumayo, isebenzisa i-DisplayPort Elternate Mode emva kwezigcawu. Ababek'esweni bayanda beza negalelo le-DisplayPort ngaphezulu kwe-USB-C, kwaye ngenxa yenqaku elibizwa ngokuba yi-MST, unokudibanisa iimonitha, zikunika uqwalaselo lokujonga izinto ezininzi ngentambo enye - ngaphandle kokuba usebenzisa iMacbook, njengoko iApple iyekile nayo. macOS. I-MST ixhaswa kwi.
Kwakhona, inyani enomdla-i-DP Elternate Mode yenye yeendlela ezimbalwa eziNxibelelanayo ezisebenzisa izikhonkwane ze-SBU eziphinda zifakwe kwi-DisplayPort AUX ngababini. Ukungabikho ngokubanzi kwezikhonkwane ze-USB-C kuthetha ukuba izikhonkwane zokucwangcisa i-DP kufuneka zingabandakanywa, ngaphandle kwe-DP ++ HDMI / DVI imo ehambelanayo, ngoko ke zonke ii-adapter ze-USB-C DP-HDMI zisebenza ngokusebenzayo i-DP-HDMI converters. I-Masking - Ngokungafani ne-DP ++, i-DP ++ ikuvumela ukuba usebenzise utshintsho lwamanqanaba kwinkxaso ye-HDMI.
Ukuba ufuna ukutshintsha iDisplayPort, uya kufuna i-DP-enabled multiplexer, kodwa okona kubaluleke kakhulu, kufuneka ukwazi ukuthumela imiyalezo yePD yesiko. Okokuqala, yonke “isibonelelo/isicelo esiyenye imowudi yeDP” yenziwa ngePD – akukho zixhathisi zaneleyo. Kwakhona akukho zikhonkwane zamahhala ze-HPD, eziluphawu olubalulekileyo kwi-DisplayPort, ngoko ke i-hotplug kunye neziganeko zokulahla zithunyelwa njengemiyalezo kwikhonkco le-PD. Ukutsho oko, akunzima kakhulu ukuyiphumeza, kwaye ndicinga ngokuphunyezwa kwe-hacker-friendly-kude kube ngoko, ukuba ufuna ukusebenzisa i-DP Elternate Mode ukukhupha i-DP okanye i-HDMI phezu kwezibuko le-USB-C, kukho iichips ezifana I-CYPD3120 ekuvumela ukuba ubhale i-firmware kule nto.
Enye yezinto eyenza i-DP Elternate Mode igqame kukuba ineendlela ezine ezinesantya esiphezulu kwi-USB-C, ikuvumela ukuba udibanise uqhagamshelo lwe-USB3 kwelinye icala lezibuko le-USB-C kunye nekhonkco elidibanisa kabini enye. Le yindlela zonke iidokhi "ze-USB3, i-Peripherals, kunye ne-HDMI Out". Ukuba isisombululo seendlela ezimbini sisithintelo kuwe, unokuthenga kwakhona i-adapter ye-quad-lane - ngenxa yokungabikho kwe-USB3, akuyi kubakho ukuhanjiswa kwedatha, kodwa unokufumana isisombululo esiphezulu okanye iireyithi zesakhelo kunye neendlela ezimbini ze-DisplayPort ezongezelelweyo.
Ndifumana i-DisplayPort Elternate Mode yenye yezona zinto zibalaseleyo malunga ne-USB-C, kwaye ngelixa ezona zitshiphu (okanye ezona zilishwa) iilaptops kunye neefowuni zingayixhasi, kulungile ukuba nesixhobo esenzayo. Ewe kunjalo, ngamanye amaxesha inkampani enkulu ifumana olo vuyo ngokuthe ngqo, njengoko wenzayo uGoogle.
Ngokukodwa, nge-USB-C ungafumana i-Thunderbolt 3, kwaye kungekudala iThunderbolt 4, kodwa ukuza kuthi ga ngoku intle kakhulu. I-Thunderbolt 3 ekuqaleni yayiluphawu lobunikazi olwathi ekugqibeleni lwavulwa yi-Intel. Kuyabonakala ukuba azivulwanga ngokwaneleyo okanye zinenye i-caveat, kwaye ekubeni izixhobo ze-Thunderbolt ezi-3 endle zisakhiwa ngokukodwa nge-Intel chips, ndiyaqikelela ukuba ukungabikho kokhuphiswano sisizathu sokuba amaxabiso ahlale ezinzileyo. indawo yedijithali. Kutheni ukhangela izixhobo zeThunderbolt kwasekuqaleni? Ukongeza kwisantya esiphezulu, kukho enye into ebulalayo.
Ufumana i-PCIe bandwidth ngaphezulu kweThunderbolt kunye nokuya kuthi ga kwi-4x bandwidth! Esi ibe sisihloko esishushu kwabo bafuna inkxaso ye-eGPU okanye ugcino lwangaphandle olukhawulezayo ngendlela ye-NVMe drives esetyenziswa ngabanye abahlaseli kwii-FPGA ezincanyathiselwe kwi-PCIe. Ukuba uneekhompyutheni ezimbini ze-Thunderbolt (umzekelo, ii-laptops ezimbini), unokuphinda udibanise usebenzisa intambo ye-Thunderbolt - oku kudala i-interface yenethiwekhi ye-speed-speed phakathi kwabo ngaphandle kweengxenye ezongezelelweyo. Ewe, ewe, i-Thunderbolt inokwenza lula i-DisplayPort kunye ne-USB3 ngaphakathi. Itekhnoloji yeThunderbolt inamandla kakhulu kwaye imnandi kubasebenzisi abaphambili.
Nangona kunjalo, konke oku kupholile kufezekiswa ngobunikazi kunye nobuchwephesha obuntsonkothileyo. I-Thunderbolt ayisiyiyo into enokwenziwa lula yi-hacker, nangona umntu kufuneka ayizame ngenye imini. Kwaye ngaphandle kweempawu ezininzi ze-Thunderbolt dock, icala lesoftware lihlala libangela iingxaki, ngakumbi xa kufikwa kwizinto ezinjengokuzama ukulala ukuze usebenze kwilaptop ngaphandle kokuwa kwe-eGPU core. Ukuba ayikacaci okwangoku, ndijonge phambili kwi-Intel ukuyidibanisa.
Ndihlala ndisithi "multiplexer". Yintoni lento? Ngamafutshane, eli candelo linceda ukuphatha ukuxhawula izandla ngesantya esiphezulu ngokujikeleza kwe-USB-C.
I-High-Speed Lane yinxalenye ye-USB-C echatshazelwa kakhulu kukujikeleza kwezibuko. Ukuba izibuko lakho le-USB-C lisebenzisa iNdlela yesantya esiphezulu, uya kudinga i-multiplexer (i-multiplexer) chip ukulawula ukujika okunokwenzeka kwe-USB-C enokwenzeka - ukulungelelanisa ukuqhelaniswa namazibuko kunye neentambo kuzo zombini iziphelo kunye nabamkeli besantya esiphezulu sangaphakathi. . kwaye ii-transmitter zihambelana nesixhobo esiqhagamshelweyo. Ngamanye amaxesha, ukuba i-chip yesantya esiphezulu yenzelwe i-USB-C, ezi ziphindaphinda zingaphakathi kwi-chip yesantya esiphezulu, kodwa zihlala zizitshiphu ezahlukeneyo. Ngaba ufuna ukongeza inkxaso ye-Hi-Speed USB-C kwisixhobo esingasixhasiyo i-Hi-Speed USB-C? Ii-Multiplexers ziya kuxhasa imisebenzi yonxibelelwano olukwisantya esiphezulu.
Ukuba isixhobo sakho sinesixhobo se-USB-C esineNdlela yesantya esiphezulu, uya kufuna i-multiplexer - iintambo ezisisigxina kunye nezixhobo ezineziqhagamshelo aziyidingi. Ngokubanzi, ukuba usebenzisa intambo ukuqhagamshela izixhobo ezibini ezinesantya esiphezulu kunye neendawo zokubeka i-USB-C, bobabini baya kufuna i-multiplexer-ukulawula ukujikeleza kwentambo luxanduva lwesixhobo ngasinye. Kumacala omabini, i-multiplexer (okanye umlawuli wePD oxhunywe kwi-multiplexer) uya kulawula isalathiso se-CC pin kwaye enze ngokufanelekileyo. Kwakhona, uninzi lwezi ziphindaphinda zisetyenziselwa iinjongo ezahlukeneyo, kuxhomekeke kwinto oyifunayo kwizibuko.
Uya kubona ii-multiplexers ze-USB3 kwiilaptops ezitshiphu ezisebenzisa kuphela i-USB 3.0 kwizibuko loHlobo lwe-C, kwaye ukuba iyayixhasa i-DisplayPort, uya kuba ne-multiplexer ngegalelo elongezelelweyo lokuxuba le miqondiso yesixhobo. Kwi-Thunderbolt, i-multiplexer iya kwakhelwa kwi-Thunderbolt chip. Kubaduni abasebenza nge-USB-C kodwa abanakho ukufikelela kwi-Thunderbolt okanye abayidingi i-Thunderbolt, i-TI kunye ne-VLI zibonelela ngenani le-multiplexers ezilungileyo ngeenjongo ezahlukeneyo. Umzekelo, bendisebenzisa i-DisplayPort ngaphezulu kwe-USB-C mva nje, kwaye i-VL170 (ibonakala ngathi yi-1: 1 clone ye-TI's HD3SS460) ijongeka njenge-chip enkulu yokusetyenziswa kwe-DisplayPort + USB3 combo.
I-multiplexers ye-USB-C exhasa i-DisplayPort (njenge-HD3SS460) ayilwenzi ulawulo lwe-CC pin kwaye ijike ukubonwa, kodwa ngumda ofanelekileyo-iDisplayPort ifuna ikhonkco lePD elichanekileyo, elibaluleke kakhulu. amandla amaninzi. Ngaba wonwabile nge-USB3 engadingi qhagamshelwano lwePD? I-VL161 yinto elula ye-USB3 multiplexer IC enegalelo le-polarity, ukuze ukwazi ukuchaza i-polarity ngokwakho.
Ukuba nawe awufuni ukubonwa kwe-polarity - ngaba i-5v kuphela i-analog PD yanele iimfuno zakho ze-USB3? Sebenzisa into efana ne-VL160 - idibanisa abamkeli be-analog PD kunye nemithombo, amandla okucubungula kunye nomzila ohamba ngesantya esiphezulu udibanisa yonke into enye. Yitshiphu yokwenyani “Ndifuna i-USB3 ngaphezulu kwe-USB-C, ndifuna ukuba yonke into ilawulelwe mna”; umzekelo, amakhadi okubamba i-HDMI yomthombo wamva nje asebenzisa i-VL160 kumazibuko e-USB-C. Ukulunga, andidingi kukhetha i-VL160 – kukho inkitha yee-microcircuits ezinjalo; "I-USB3 mux ye-USB-C, yenza konke" mhlawumbi lolona hlobo ludumileyo lwe-chip enxulumene ne-USB-C.
Kukho iindlela ezininzi ze-USB-C zelifa. Eyokuqala, endingayi kulila ngayo, yiNdlela Eyenye ye-HDMI; ibeka ngokulula izikhonkwane ze-HDMI isinxibelelanisi phezu kwezikhonkwane zesiqhagamshelanisi se-USB-C. Inokukunika i-HDMI ngaphezulu kwe-USB-C, kwaye kubonakala ngathi ibikhona kwii-smartphones ixesha elifutshane. Nangona kunjalo, kufuneka ikhuphisane ngokukhululeka kokuguqula kwi-HDMI I-DisplayPort Alternate Mode, ngelixa ukuguqulwa kwe-HDMI-DP kudla ngokuba yindleko kwaye ayikwazi ukusetyenziswa ngokubambisana ne-USB 3.0 kuba i-HDMI idinga iibini ezine ezahlukeneyo kunye ne-HDMI imithwalo yelayisenisi, ngokutsho kubonakala ngathi. ukukhuthaza uphuhliso lwe-HDMI Alt Mode emhlabeni. Ndiyakholelwa ngokwenene ukuba kufuneka ihlale apho kuba andikholelwa ukuba umhlaba wethu unokuphuculwa ngokongeza i-HDMI.
Nangona kunjalo, enye inomdla ngokwenene - ibizwa ngokuba yiVirtualLink. Ezinye iinkampani ezinkulu zetekhnoloji zisebenza kubuchule be-USB-C kwi-VR - emva kwayo yonke loo nto, ipholile xa i-headset yakho yeVR ifuna intambo enye kuyo yonke into. Nangona kunjalo, iiglasi ze-VR zifuna i-high-resolution-display-display, i-high-frame-interfaces yevidiyo, kunye noqhagamshelo lwedatha olunesantya esiphezulu kwiikhamera ezongezelelweyo kunye ne-sensor, kunye nesiqhelo "ikhonkco elidibanisa i-DisplayPort + USB3" indibaniselwano ayikwazi ukunika iimpawu ezinjalo. ngelo xesha. Wenza ntoni ke ngoko
Iqela leVirtualLink lithi lilula: ungaqhagamshela ezimbini USB2 izibini ezingafunekiyo kwisidibanisi se-USB-C kwaye usebenzise izikhonkwane ezine ukudibanisa i-USB3. Khumbula i-USB2 ukuya kwi-USB3 yokuguqula i-chip endiyikhankanyileyo kwinqaku elifutshane kwisiqingatha sonyaka odlulileyo? Ewe, eyona njongo yayo yayiyiVirtualLink. Ewe, olu seto lufuna intambo yesiko ebiza kakhulu kunye neeperi ezimbini ezongezelelweyo ezikhuselweyo, kwaye ifuna ukuya kuthi ga kwi-27W yamandla avela kwiPC, okt imveliso ye-9V, engafane ibonwe kwiitshaja zodonga ze-USB-C okanye izixhobo eziphathwayo. amandla. Umahluko phakathi kwe-USB2 kunye ne-USB3 iyakhathaza kwabanye, kodwa kwiVR VirtualLink ibonakala iluncedo kakhulu.
Ezinye ii-GPUs ziza nenkxaso ye-VirtualLink, kodwa oko akwanelanga ekuhambeni kwexesha, kwaye iilaptops ezaziwayo ngokuhlala zinqongophele izibuko ze-USB-C azikwenzi. Oku kubangele iValve, umdlali ophambili kwisivumelwano, ukuba abuye umva ekongezeni ukuhlanganiswa kweVirtualLink kwiSalathiso seValve, kwaye yonke into yehla ukusuka apho. Ngelishwa, iVirtualLink ayizange idume. Inokuba yinto enomdla - intambo enye iya kuba lukhetho olukhulu kubasebenzisi beVR, kwaye ifuna amandla ombane aphezulu ngaphezulu kwe-USB-C iya kusinika ngaphezulu kwe-5V ngokusebenza kwePD. Amazibuko-Azikho iilaptops okanye iiPC ezibonelela ngezi mpawu kule mihla. Ewe, isikhumbuzi nje- ukuba unezibuko le-USB-C kwidesktop yakho okanye kwilaptop, ngokuqinisekileyo liya kukunika i-5V, kodwa awuzukufumana nto iphezulu.
Noko ke, makhe sijonge kwicala eliqaqambileyo. Ukuba unenye yezi GPUs ezinezibuko le-USB-C, iya kuxhasa zombini i-USB3 kunye ne-DisplayPort!
Into entle malunga ne-USB-C kukuba abathengisi okanye abahlaseli banokuchaza enye indlela yabo ukuba bayafuna, kwaye ngelixa iadaptha iya kuba yeyomnini-siqingatha, ngokusisiseko iseyi-USB-C port yokutshaja kunye nokudluliselwa kwedatha. Ngaba uyafuna iNdlela Eyenye ye-Ethernet okanye i-SATA ye-Dual Port? yenze. Zimkile iintsuku zokuzingela iziqhagamshelo ezingacacanga kakhulu zezixhobo zakho njengoko idokhi nganye kunye nesinxibelelanisi sentlawulo sahlukile kwaye sinokubiza ngaphezulu kwe-10 yeedola ukuba kunqabile ngokwaneleyo ukukufumana.
Ayizizo zonke izibuko ze-USB-C ezifuna ukuphumeza zonke ezi mpawu, kwaye ezininzi azikwenzi. Nangona kunjalo, abantu abaninzi bayayenza, kwaye njengoko ixesha lihamba, sifumana ukusebenza ngakumbi nangakumbi kwiizibuko ze-USB-C eziqhelekileyo. Olu manyano kunye nokulinganisa kuya kuhlawula ngexesha elide, kwaye nangona kuya kubakho ukuphambuka kwamaxesha ngamaxesha, abavelisi baya kufunda ukujongana nabo ngobuchule.
Kodwa inye into endihlala ndizibuza yona kukuba kutheni ukujikeleziswa kweplagi kungaphathwa ngokubeka i- + kunye – iingcingo kumacala ahlukeneyo. Ke, ukuba iplagi iqhagamshelwe ngendlela "engalunganga", + iya kuqhagamshelwa kuyo - kwaye - iya kudityaniswa +. Emva kokuchaza umqondiso kumamkeli, konke okufuneka ukwenze kukubuyisela umva amasuntswana ukuze ufumane idatha echanekileyo.
Ngokusisiseko, ingxaki yimfezeko yomqondiso kunye ne-crosstalk. Yiba nomfanekiso, yithi, isidibanisi esi-8, imiqolo emibini yesine, 1/2/3/4 kwelinye icala kunye no-5/6/7/8 kwelinye, apho u-1 echasana no-5. Masithi ufuna ipere +/- fumana /sasaza. Ungazama ukubeka i-Tx+ kwi-pin 1, Tx- kwi-pin 8, Rx+ kwi-pin 4, kunye ne-Rx- kwi-pin 5. Ngokucacileyo, ukufaka umva kuphela i-swaps +/-.
Kodwa umqondiso wombane awuhambi ngaphaya kwepini yomqondiso, uhamba phakathi komqondiso kunye nokubuya kwawo kumhlaba wombane. I-Tx-/Rx- kufuneka ibe "yimbuyekezo" ye-Tx+/Rx+ (kwaye ngokucacileyo ngokuphambeneyo). Oku kuthetha ukuba iisignali ze-Tx kunye ne-Rx ziyadibana.
"Ungazama" ukulungisa oku ngokwenza imiqondiso ehambelanayo ingalungelelaniswa - ngokubalulekileyo ukubeka inqwelomoya ephantsi komhlaba eqinile ecaleni kophawu ngalunye. Kodwa kulo mzekelo, ulahlekelwa yimeko yokungaxoki kwengxolo yokwahlukana kwesibini, nto leyo ethetha ukuba i-crosstalk elula esuka ku-Tx+/Rx- ejongene nenye ayirhoxisi.
Ukuba uthelekisa oku nokubeka i-Tx +/Tx- kwizikhonkwane 1/2 kunye ne-7/8 kunye ne-Rx+/Rx- kwizikhonkwane 3/4 kunye ne-5/6 nge-multiplexer, ngoku izibonakaliso ze-Tx/Rx azinqumli kwaye zonke ii-crosstalk ezibangelwayo. kubafowunelwa i-Tx okanye i-Rx, iyakuba yinto eqhelekileyo kuzo zombini izibini kwaye ihlawulwe ngokuyinxenye.
(Ngokucacileyo, isiqhagamshelo sokwenyani siya kuba nezikhonkwane ezininzi zomhlaba, khange ndiyikhankanye ngenxa yobufutshane.)
> Ukumanyanisa kuzisa ukuhambelana ekunzima ukukuxela, i-IMO into eziswa yi-USB-C lihlabathi nje lokungahambelani okufihlakeleyo ekunzima ukukuqonda kwi-tech-savvy kuba i-specs ayichazi nokuba yintoni enokuyenza / ayikwazi ukuyenza. kwaye iya kuba mbi ngakumbi njengoko ezinye iindlela zongezwa, kwaye ezo ntambo zinemiba nazo…
Uninzi lweziqhagamshelo zamandla zangaphambi kwe-USB-C beziziqhagamshelo zomphanda, ezingabizi kakhulu kune-USB-C. Ngelixa uninzi lwezikhululo zezikhululo zokumisa zinokuba neziqhagamshelo ezingaqhelekanga eziyinkathazo, zihlala zikwazi ukufikelela ngokuthe ngqo kwi-PCI-E kunye nezinye iibhasi, kwaye zihlala zineendlela ezininzi - ngokukhawuleza kune-USB-C, noko xa kuthelekiswa nexesha lakho. … I-USB-C yayingelophupha elibi kubagezeli ababefuna i-USB-2 kuphela, isiqhagamshelo esixabisa kakhulu, kwaye isiqhagamshelo sedokhi sasingafanelekanga, kodwa xa ufuna intsonkothe ngokwenene. Xa kufikwa kwizakhono zesantya esiphezulu, i-USB-C iyithatha iyise kwelinye inqanaba lokusebenza.
Ngokwenene, yayiyimbono yam leyo. Umgangatho uvumela yonke into, kodwa akukho mntu uya kuphumeza nantoni na enokwenza kube nzima kuzo naziphi na izixhobo ezibini ze-USB-C ukusebenzisana. Ndidlule kuyo; Ndisebenzise ithebhulethi yam ngeadaptha yamandla ye-USB-A kunye ne-USB-A ukuya kwintambo ye-USB-C iminyaka. Oku kundivumela ukuba ndiphathe iadaptha yethebhulethi kunye nefowuni yam. Ndithenge ilaptop entsha kwaye iadaptha endala ayizukuyihlawulisa – emva kokufunda iposti yangaphambili, ndiye ndaqonda ukuba ifuna enye yeevoltage eziphezulu ezingenakubonelelwa yi-USB-A. Kodwa ukuba awuyazi into ecacileyo yolu jongano oluntsonkothileyo, ke akucaci ukuba kutheni ikhebula elidala lingasebenzi.
Kwanomboneleli omnye akanakwenza oku. Safumana yonke into kuDell eofisini. Dell laptop, Dell docking station (USB3), kunye Dell monitor.
Nokuba yeyiphi idokhi endiyisebenzisayo, ndifumana impazamo ethi "Bonisa uqhagamshelo", impazamo "yokutshaja", sisinye kuphela izikrini ezibini ezisebenzayo, okanye aziyi kuqhagamshelwa kwidokhi konke konke. Yisiphithiphithi.
Uhlaziyo lweFirmware kufuneka lwenziwe kwi-motherboard, kwisikhululo sokumisa, kwaye abaqhubi kufuneka bahlaziywe. Ekugqibeleni yenza ukuba into embi isebenze. I-USB-C ibisoloko ibuhlungu.
Ndisebenzisa izikhululo ze-non-Dell kwaye yonke into ihambe kakuhle! =D Ukwenza idokhi ye-USB-C efanelekileyo akubonakali kunzima kangako - bahlala besebenza kakuhle de ube udibana nezinto ezingaqhelekanga zeThunderbolt, kwaye nalapho kukho iingxaki kwindawo “yeplagi, khulula, sebenza”. Andizuxoka, okwangoku bendifuna ukubona iskimu sebhodi yomama yelaptop yakwaDell enezi zikhululo zokumisa.
U-Arya ulungile. Zonke iingxaki zanyamalala xa ndithenga i-USB-C enexabiso eliphantsi eliqhekezayo elivela eAmazon. Iibhodi zekhibhodi, iiwebcams, iidongles ze-USB zinokudityaniswa, iiplagi zokujonga kwi-USB-C, HDMI, okanye i-DP port kwilaptop, kwaye ilungele ukuhamba. Ndiye ndaxelelwa into emandiyenze ngumfo wakwa-IT owathi idokhi yaseDell ayifanelekanga.
Hayi, ezi zizidenge zikaDell - ngokucacileyo bagqibe kwelokuba benze imveliso ingahambelani ne-USB-C xa besebenzisa isinxibelelanisi esifanayo.
Ewe, ukuba uyandibuza, isixhobo esifana nethebhulethi kufuneka sicacise ngakumbi malunga "kutheni singahlawuliswa ngokupheleleyo". Umyalezo ozivelelayo "Ubuncinci i-9V @ 3A itshaja ye-USB-C efunekayo" iya kusombulula iingxaki zabantu ezinje kwaye wenze kanye le nto ilindelwe ngumenzi wethebhulethi. Nangona kunjalo, asikwazi nokukholelwa ukuba nayiphi na kubo iya kukhulula uhlaziyo lwe-firmware enye emva kokuba isixhobo sithengisiwe.
Hayi nje ngexabiso eliphantsi, kodwa namandla. Zingaphi iziqhagamshelo ezaphukileyo ze-USB ozibonileyo kwizixhobo ezahlukeneyo? Ndihlala ndikwenza oku - kwaye ngesiqhelo isixhobo esinjalo siyalahlwa, kuba akunakwenzeka ngokoqoqosho ukusilungisa ...
Izixhumi ze-USB, eziqala nge-micro USB, ziye zancinci kakhulu, kwaye kufuneka zihlale ziplagi kwaye uzikhuphe, ngokuqhelekileyo ngabantu abangazilungelelanisi ngokufanelekileyo, basebenzise amandla amaninzi, bebashukumisa ukusuka kwelinye icala ukuya kwelinye, kwenza izihlanganisi zibe zibi. Kwidatha, oku kunokunyamezela, kodwa ngenxa yokuba i-USB-C ngoku isetyenziselwa ukunika amandla yonke into ukusuka kwii-smartwatches ukuya kwii-laptops zonke kunye nazo zonke iintlobo zezixhobo ze-elektroniki ezingasebenzisi datha konke konke, iziqhagamshelo ezonakalisiweyo ziya kuxhaphake ngakumbi. . Okukhona isikhathaza – kwaye akukho sizathu sibambekayo.
Kulungile, ndibone kuphela isinxibelelanisi sombhobho omnye owaphukileyo kwaye kulula ukuyilungisa (ngaphandle kwenguqulo ye-Dell BS, isebenza kuphela kwitshaja yobunikazi enokunxibelelana nayo, ethambileyo, ungonakalisa nokuba awuze ukhwele ibhayisekile
Iziqhagamshelo zemigqomo zinikwa ireyithingi yesiqingatha somjikelo (okanye ngaphantsi) kwizihlanganisi eziqhelekileyo ze-USB-C. Oku kungenxa yokuba i-pin ephakathi iguquguquka rhoqo xa ifakiwe, kwaye nge-USB, ingalo ye-lever imfutshane. Ndibone iijacks ezininzi zemiphanda ezonakaliswe kukusetyenziswa.
Esinye sezizathu zokuba i-USB-C ibonakale ingathembekanga kangako ziziqhagamshelo ezitshiphu okanye iintambo. Ukuba ufumana imveliso ekhangeleka “esisitayileyo” okanye “epholileyo” enenaliti yokubumba okanye nantoni na, inokuba bububhanxa. Ifumaneka kuphela kubavelisi abakhulu beentambo kunye neenkcukacha kunye nemizobo.
Esinye isizathu kukuba usebenzisa i-USB-C ngaphezu kweziqhagamshelo ezinombhobho. Iifowuni zidibanisa kwaye zikhuphe yonke imihla, ngamanye amaxesha amaxesha amaninzi.
