Ib qho ntawm qhov zoo tshaj plaws ntawm USB-C yog nws lub peev xwm siab ceev. Lub pinout muab rau koj plaub qhov sib txawv ntawm qhov sib txawv thiab ntau qhov sib txawv qis, tso cai rau koj hloov cov ntaub ntawv loj los ntawm cov khoom sib txuas rau tsawg dua ib dime. Tsis yog txhua lub cuab yeej siv cov yam ntxwv no, lossis lawv yuav tsum - USB-C tau tsim los kom nkag mus tau rau txhua yam khoom siv nqa tau. Txawm li cas los xij, thaum koj lub cuab yeej xav tau kev kub ceev tshaj USB-C, koj yuav pom tias USB-C tuaj yeem muab rau koj qhov kev kub ceev thiab nws ua tau zoo npaum li cas.
Lub peev xwm kom tau txais kev sib txuas ceev los ntawm USB-C yog hu ua Alternate Mode, lossis Hloov Hom luv luv. Peb qhov kev xaiv uas koj tuaj yeem ntsib niaj hnub no yog USB3, DisplayPort, thiab Thunderbolt, nrog qee qhov twb ploj lawm, zoo li HDMI thiab VirtualLink, thiab qee qhov nce ntxiv, xws li USB4. Feem ntau lwm hom xav tau USB-C digital kev sib txuas lus siv qee hom PD txuas kev xa xov. Txawm li cas los xij, tsis yog txhua USB3s yog qhov yooj yim tshaj plaws. Cia wb mus saib seb qhov kev xaiv template ua li cas.
Yog tias koj tau pom tus pinout, koj tau pom cov pins siab ceev. Niaj hnub no kuv xav qhia koj tias dab tsi interfaces muaj los ntawm cov pins hnub no. Qhov no tsis yog ib daim ntawv teev tag nrho lossis dav - Kuv yuav tsis tham txog tej yam xws li USB4, piv txwv li, ib nrab vim kuv tsis paub txaus txog nws lossis muaj kev paub txog nws; Nws muaj kev nyab xeeb los xav tias peb yuav tau txais ntau USB-nruab cov khoom siv yav tom ntej -C rau cov khoom siv ceev ceev. Tsis tas li ntawd, USB-C hloov pauv tau txaus uas cov neeg nyiag nkas tuaj yeem nthuav tawm Ethernet lossis SATA hauv USB-C sib xws - yog tias qhov koj tab tom nrhiav, tej zaum qhov kev tshuaj xyuas no tuaj yeem pab koj txheeb xyuas nws.
USB3 yog heev, yooj yim heev - tsuas yog ob peb TX thiab ob peb RX, txawm hais tias tus nqi hloov pauv ntau dua li USB2, nws tswj tau rau cov neeg nyiag nkas. Yog tias koj siv ntau txheej PCB nrog USB3 teeb liab impedance tswj thiab hwm rau cov khub sib txawv, koj qhov kev sib txuas USB3 feem ntau yuav ua haujlwm zoo.
Tsis tau hloov ntau npaum li cas rau USB3 dhau USB-C - koj yuav muaj multiplexer los tswj kev sib hloov, tab sis qhov ntawd yog hais txog nws. USB3 multiplexers muaj ntau, yog li yog tias koj ntxiv USB3-enabled USB-C chaw nres nkoj rau koj lub motherboard, koj tsis zoo li yuav ua rau muaj teeb meem. Kuj tseem muaj Dual Channel USB3, uas siv ob qho tib si USB3 raws li kom nce bandwidth, tab sis hackers feem ntau tsis khiav mus rau lossis xav tau qhov no, thiab Thunderbolt nyhav los npog thaj chaw no zoo dua. Xav hloov lub USB3 ntaus ntawv mus rau ib tug USB-C ntaus ntawv? Txhua yam koj xav tau yog ib qho multiplexer. Yog tias koj tab tom xav txog kev txhim kho MicroUSB 3.0 connector ntawm koj lub motherboard rau koj cov khoom siv siab, ces kuv hais lus zoo tab sis thov kom koj hloov siab thiab nruab USB-C connector thiab VL160 rau nws.
Yog tias koj tab tom tsim lub USB3 ntaus ntawv nrog lub ntsaws, koj tsis tas yuav muaj ntau lub tshuab los tswj kev sib hloov - qhov tseeb, koj tsis tas yuav muaj kev sib hloov nrhiav kom pom. Ib qho kev tswj tsis tau 5.1kΩ resistor yog txaus los tsim ib lub USB3 flash drive uas ntsaws ncaj qha rau hauv USB-C chaw nres nkoj, los yog tsim ib tug USB-C txiv neej rau poj niam USB-A 3.0 adapter. Raws li qhov chaw mus, koj tuaj yeem zam kev siv multiplexer yog tias koj muaj kev sib txuas USB3 dawb rau kev txi, uas tsis yog txhua yam ntau. Kuv tsis paub txaus txog dual channel USB3 kom paub tseeb tias dual channel USB3 txhawb kev sib txuas zoo li no, tab sis kuv xav tias cov lus teb "tsis yog" yuav zoo dua li "yog"!
DisplayPort (DP) yog qhov kev sib txuas zoo rau kev sib txuas cov kev daws teeb meem siab - nws tau dhau HDMI ntawm desktops, dominating lub built-in zaub qhov chaw nyob rau hauv daim ntawv ntawm eDP, thiab xa cov kev daws teeb meem siab tshaj ib tug cable, feem ntau zoo dua HDMI. Nws tuaj yeem hloov mus rau DVI lossis HDMI siv tus nqi pheej yig adapter uas siv tus qauv DP ++ thiab tsis muaj nuj nqis xws li HDMI. Nws ua rau muaj kev nkag siab zoo rau VESA alliance ua haujlwm nrog pab pawg USB los siv DisplayPort kev txhawb nqa, tshwj xeeb tshaj yog raws li DisplayPort transmitters hauv SoCs tau dhau los ua neeg nyiam.
Yog tias koj siv lub chaw nres nkoj nrog HDMI lossis VGA tso zis, nws siv DisplayPort Lwm Hom tom qab qhov xwm txheej. Cov saib tau nce zuj zus tuaj nrog DisplayPort cov tswv yim dhau USB-C, thiab ua tsaug rau qhov tshwj xeeb hu ua MST, koj tuaj yeem txuas cov saib, muab rau koj ntau qhov kev teeb tsa nrog ib lub cable - tshwj tsis yog koj siv Macbook, raws li Apple tau tso tseg nrog macOS. MST tau txais kev txhawb nqa hauv .
Tsis tas li ntawd, qhov tseeb nthuav - DP Hloov Hom yog ib qho ntawm ob peb Txoj Kev Hloov Kho uas siv SBU tus pins uas tau rov ua dua rau DisplayPort AUX khub. Feem ntau tsis muaj USB-C pins kuj txhais tau hais tias DP configuration pins yuav tsum raug cais tawm, tshwj tsis yog rau DP ++ HDMI / DVI kev sib raug zoo hom, yog li txhua tus USB-C DP-HDMI adapters tau txais txiaj ntsig zoo DP-HDMI converters. Masking - Tsis zoo li DP ++, DP ++ tso cai rau koj siv qib hloov rau HDMI kev txhawb nqa.
Yog tias koj xav hloov DisplayPort, koj yuav xav tau DP-enabled multiplexer, tab sis qhov tseem ceeb tshaj, koj yuav tsum muaj peev xwm xa cov lus PD. Ua ntej, tag nrho "pab nyiaj / thov hloov DP hom" yog ua tiav los ntawm PD - tsis muaj cov resistors txaus. Kuj tseem tsis muaj tus pins pub dawb rau HPD, uas yog lub teeb liab tseem ceeb hauv DisplayPort, yog li cov xwm txheej kub kub thiab rho tawm raug xa raws li cov lus hla ntawm PD txuas. Uas tau hais tias, nws tsis nyuaj heev rau kev siv, thiab kuv xav txog kev siv hacker-phooj ywg - txog thaum ntawd, yog tias koj xav siv DP Hloov Hom los tso tawm DP lossis HDMI dhau ntawm USB-C chaw nres nkoj, muaj cov chips zoo li cov CYPD3120 uas tso cai rau koj sau firmware rau qhov no.
Ib qho ntawm cov khoom uas ua rau DP Alternate Mode sawv tawm yog tias nws muaj plaub txoj kab nrawm ntawm USB-C, tso cai rau koj los ua ke USB3 kev sib txuas ntawm ib sab ntawm USB-C chaw nres nkoj thiab dual-link DisplayPort kev sib txuas ntawm lub lwm yam. Qhov no yog li cas tag nrho "USB3 Ports, Peripherals, thiab HDMI Out" docks ua haujlwm. Yog hais tias ob txoj kab kev daws teeb meem yog ib qho kev txwv rau koj, koj tuaj yeem yuav ib lub quad-txoj kab adapter - vim tsis muaj USB3, yuav tsis muaj cov ntaub ntawv hloov mus, tab sis koj tuaj yeem tau txais kev daws teeb meem siab dua lossis tus nqi nrog ob txoj kab DisplayPort ntxiv.
Kuv pom DisplayPort Lwm Hom yog ib qho zoo tshaj plaws txog USB-C, thiab thaum pheej yig tshaj (lossis feem ntau tsis muaj hmoo) laptops thiab xov tooj tsis txhawb nqa, nws yog qhov zoo uas muaj cov cuab yeej ua tau. Tau kawg, qee zaum lub tuam txhab loj tau txais kev xyiv fab ncaj qha, zoo li Google tau ua.
Tshwj xeeb, ntawm USB-C koj tuaj yeem tau txais Thunderbolt 3, thiab tsis ntev Thunderbolt 4, tab sis tam sim no nws tsuas yog zoo heev. Thunderbolt 3 yog Ameslikas ib qho tshwj xeeb tshwj xeeb uas tau qhib thaum kawg los ntawm Intel. Pom tau tias lawv tsis qhib txaus lossis muaj lwm qhov caveat, thiab txij li Thunderbolt 3 cov khoom siv hauv cov tsiaj qus tseem tab tom tsim tshwj xeeb nrog Intel chips, Kuv tabtom twv qhov tsis muaj kev sib tw yog vim li cas vim li cas cov nqi tseem nyob ruaj khov. thaj chaw digital. Vim li cas koj tab tom nrhiav Thunderbolt li thawj qhov chaw? Ntxiv nrog rau kev nrawm dua, muaj lwm yam kev tua neeg.
Koj tau txais PCIe bandwidth hla Thunderbolt nrog rau txog li 4x bandwidth! Qhov no tau yog lub ntsiab lus kub rau cov neeg xav tau kev txhawb nqa eGPU lossis ceev ceev sab nraud cia hauv daim ntawv ntawm NVMe tsav uas qee tus neeg nyiag khoom siv rau PCIe-txuas nrog FPGAs. Yog tias koj muaj ob lub Thunderbolt-enabled computers (piv txwv li, ob lub laptops), koj tuaj yeem txuas rau lawv siv Thunderbolt-enabled cable - qhov no tsim kom muaj kev sib txuas ceev ceev ntawm lawv yam tsis muaj cov khoom ntxiv. Yog lawm, tau kawg, Thunderbolt tuaj yeem yooj yim tunnel DisplayPort thiab USB3 sab hauv. Thunderbolt thev naus laus zis muaj zog heev thiab qab heev rau cov neeg siv siab heev.
Txawm li cas los xij, tag nrho cov kev txias no tau ua tiav los ntawm cov cuab yeej cuab tam thiab cov txheej txheem thev naus laus zis. Thunderbolt tsis yog ib yam dab tsi uas ib leeg hacker tuaj yeem tsim tau yooj yim, txawm tias ib tus neeg yuav tsum sim nws ib hnub. Thiab txawm hais tias Thunderbolt dock muaj ntau yam nta, sab software feem ntau ua rau muaj teeb meem, tshwj xeeb tshaj yog thaum nws los txog rau tej yam xws li sim mus pw tsaug zog ua hauj lwm ntawm lub laptop yam tsis muaj crashing lub eGPU core. Yog tias nws tseem tsis tau pom tseeb, kuv tos ntsoov rau Intel muab nws ua ke.
Kuv pheej hais tias "multiplexer". Qhov no yog dab tsi? Nyob rau hauv luv luv, qhov no yuav pab tswj lub high-ceev tes tuav raws li USB-C rotation.
High-Speed Lane yog ib feem ntawm USB-C uas feem ntau cuam tshuam los ntawm kev sib hloov chaw nres nkoj. Yog tias koj qhov chaw nres nkoj USB-C siv Txoj Kev Kub Ceev, koj yuav xav tau ib lub multiplexer (multiplexer) nti los tswj ob qhov ua tau USB-C lem - aligning the orientation of the ports and cables at two end with the real high speed receivers. . thiab transmitters yog sib npaug rau cov khoom siv txuas nrog. Qee lub sij hawm, yog tias lub siab ceev nti yog tsim rau USB-C, cov multiplexers no nyob rau hauv lub siab ceev nti, tab sis feem ntau lawv yog nyias nyias. Xav ntxiv Hi-Speed USB-C kev txhawb nqa rau lub cuab yeej uas tsis tau txhawb nqa Hi-Speed USB-C? Multiplexers yuav txhawb nqa kev sib txuas lus ceev ceev.
Yog tias koj lub cuab yeej muaj USB-C txuas nrog Txoj Kev Kub Ceev, koj yuav xav tau ib lub multiplexer – tsau cables thiab pab kiag li lawm nrog connectors tsis xav tau. Feem ntau, yog tias koj siv ib lub cable los txuas ob lub cuab yeej ceev nrog USB-C qhov, lawv ob leeg yuav xav tau ib qho multiplexer - tswj kev sib hloov cable yog lub luag haujlwm ntawm txhua lub cuab yeej. Ntawm ob sab, lub multiplexer (los yog PD maub los txuas nrog multiplexer) yuav tswj cov kev taw qhia ntawm CC tus pin thiab ua raws li. Tsis tas li ntawd, ntau ntawm cov multiplexers no yog siv rau ntau lub hom phiaj, nyob ntawm seb koj xav tau dab tsi los ntawm qhov chaw nres nkoj.
Koj yuav pom multiplexers rau USB3 hauv cov laptops pheej yig uas tsuas yog siv USB 3.0 ntawm hom-C chaw nres nkoj, thiab yog tias nws txhawb nqa DisplayPort, koj yuav muaj lub multiplexer nrog ib qho kev tawm tswv yim ntxiv los sib xyaw cov khoom siv no. Hauv Thunderbolt, lub multiplexer yuav ua rau hauv Thunderbolt nti. Rau cov neeg nyiag nkas uas ua haujlwm nrog USB-C tab sis tsis muaj kev nkag mus rau Thunderbolt lossis tsis xav tau Thunderbolt, TI thiab VLI muab ntau tus lej zoo rau ntau lub hom phiaj. Piv txwv li, kuv tau siv DisplayPort dhau USB-C tsis ntev los no, thiab VL170 (zoo li yog 1: 1 clone ntawm TI's HD3SS460) zoo li lub nti zoo rau DisplayPort + USB3 combo siv.
USB-C multiplexers uas txhawb nqa DisplayPort (xws li HD3SS460) tsis yog ib txwm ua CC tus pin tswj thiab tig kom pom, tab sis qhov no yog qhov kev txwv tsim nyog - DisplayPort yuav tsum muaj cov ntawv thov tshwj xeeb PD txuas, uas yog qhov tseem ceeb heev. multiplexer muaj peev xwm. Koj puas zoo siab nrog USB3 uas tsis xav tau kev sib txuas PD? VL161 yog ib qho yooj yim USB3 multiplexer IC nrog polarity input, yog li koj tuaj yeem txhais qhov polarity koj tus kheej.
Yog tias koj tseem tsis xav tau kev kuaj pom polarity - puas yog 5v nkaus xwb analog PD txaus rau koj cov kev xav tau USB3? Siv ib yam dab tsi zoo li VL160 - nws muab cov analog PD txais thiab cov peev txheej, ua lub zog thiab kev khiav ceev nrawm sib cuam tshuam tag nrho hauv ib qho. Nws yog lub nti tiag tiag "Kuv xav tau USB3 dhau USB-C, Kuv xav kom txhua yam tswj tau rau kuv"; Piv txwv li, tsis ntev los no qhib qhov chaw HDMI ntes phaib siv VL160 rau lawv cov chaw nres nkoj USB-C. Yuav kom ncaj ncees, kuv tsis tas yuav tawm ib leeg ntawm VL160 - muaj ntau ntau ntawm cov microcircuits; "USB3 mux rau USB-C, ua txhua yam" yog tej zaum hom nrov tshaj plaws ntawm USB-C ntsig txog nti.
Muaj ntau yam qub qub USB-C alternate hom. Thawj qhov, uas kuv yuav tsis tso kua muag rau, yog HDMI Hloov Hom; Nws tsuas tso cov pins ntawm HDMI connector hla tus pins ntawm USB-C connector. Nws tuaj yeem muab rau koj HDMI hla USB-C, thiab nws zoo li tau muaj nyob rau ntawm lub xov tooj smartphones rau lub sijhawm luv luv. Txawm li cas los xij, nws yuav tsum tau sib tw nrog qhov yooj yim ntawm kev hloov mus rau HDMI DisplayPort Lwm Hom, thaum HDMI-DP hloov dua siab tshiab feem ntau raug nqi thiab tsis tuaj yeem siv nrog USB 3.0 vim HDMI xav tau plaub qhov sib txawv thiab HDMI daim ntawv tso cai hnab nqa khoom, raws li pom tau tias yog spurring txoj kev loj hlob ntawm HDMI Alt hom rau hauv av. Kuv ntseeg tiag tiag nws yuav tsum nyob ntawd vim kuv tsis ntseeg tias peb lub ntiaj teb tuaj yeem txhim kho los ntawm kev ntxiv HDMI ntxiv.
Txawm li cas los xij, lwm tus yog qhov nthuav heev - nws hu ua VirtualLink. Qee lub tuam txhab thev naus laus zis loj tau ua haujlwm ntawm USB-C peev xwm hauv VR - tom qab tag nrho, nws zoo nkauj heev thaum koj lub mloog pob ntseg VR tsuas yog xav tau ib lub cable rau txhua yam. Txawm li cas los xij, VR tsom iav yuav tsum muaj kev daws teeb meem siab dual-duab, siab-thav duab-tus nqi video interfaces, nrog rau cov ntaub ntawv ceev ceev sib txuas rau cov koob yees duab ntxiv thiab cov sensors, thiab ib txwm "dual-link DisplayPort + USB3" ua ke tsis tuaj yeem muab cov yam ntxwv zoo li no. thaum lub sijhawm. Thiab koj ua li cas thaum ntawd
Pab pawg VirtualLink hais tias nws yooj yim: koj tuaj yeem txuas ob lub USB2 rov ua tsis tau txuas mus rau USB-C txuas thiab siv plaub tus pins los txuas USB3. Nco ntsoov USB2 rau USB3 hloov dua siab tshiab nti uas kuv tau hais hauv ib tsab xov xwm luv luv ib nrab xyoo dhau los? Yog lawm, nws lub hom phiaj qub yog VirtualLink. Tau kawg, qhov kev teeb tsa no yuav tsum muaj cov kab hluav taws xob kim dua thiab ob lub thaiv thaiv ntxiv, thiab yuav tsum muaj txog li 27W ntawm lub zog ntawm PC, piv txwv li 9V tso zis, uas tsis tshua pom ntawm USB-C phab ntsa chargers lossis cov khoom siv txawb. zog. Qhov txawv ntawm USB2 thiab USB3 yog kev ntxhov siab rau qee tus, tab sis rau VR VirtualLink zoo li muaj txiaj ntsig zoo.
Qee GPUs tuaj nrog VirtualLink kev txhawb nqa, tab sis qhov ntawd tsis txaus nyob rau lub sijhawm ntev, thiab cov khoos phis tawj tsis zoo rau feem ntau tsis muaj USB-C chaw nres nkoj tsis yog. Qhov no ua rau Valve, tus neeg ua si tseem ceeb hauv kev pom zoo, thim rov qab los ntawm kev ntxiv VirtualLink kev koom ua ke rau Valve Index, thiab txhua yam poob qis los ntawm qhov ntawd. Hmoov tsis zoo, VirtualLink yeej tsis tau nrov. Nws yuav yog lwm txoj kev nthuav dav - ib lub cable yuav yog qhov kev xaiv zoo rau cov neeg siv VR, thiab xav tau qhov hluav taws xob ntau dua li USB-C tseem yuav muab rau peb ntau dua 5V nrog PD functionality. Ports - Tsis yog lub laptops lossis PCs muab cov yam ntxwv no hnub no. Yog lawm, tsuas yog ceeb toom - yog tias koj muaj USB-C chaw nres nkoj ntawm koj lub desktop lossis laptop, nws yuav muab rau koj 5V, tab sis koj yuav tsis tau txais dab tsi siab dua.
Txawm li cas los xij, cia peb saib qhov kaj. Yog tias koj muaj ib qho ntawm cov GPU no nrog USB-C chaw nres nkoj, nws yuav txhawb nqa USB3 thiab DisplayPort!
Qhov zoo tshaj plaws ntawm USB-C yog cov neeg muag khoom lossis cov neeg nyiag nkas tuaj yeem txhais lawv tus kheej hloov hom yog tias lawv xav tau, thiab thaum lub adapter yuav yog ib tus tswv, nws tseem ceeb tseem yog USB-C chaw nres nkoj rau them thiab xa cov ntaub ntawv. Xav Ethernet Hloov Hom lossis Dual Port SATA? ua nws. Ploj mus yog hnub uas yuav tsum tau mus yos hav zoov tsis tshua muaj neeg sib txuas rau koj cov khoom siv vim tias txhua qhov chaw nres nkoj thiab tus nqi sib txuas sib txawv thiab tuaj yeem raug nqi nce mus txog $ 10 txhua qhov yog tsawg txaus los nrhiav.
Tsis yog txhua qhov chaw nres nkoj USB-C yuav tsum siv tag nrho cov yam ntxwv no, thiab ntau yam tsis ua. Txawm li cas los xij, ntau tus neeg ua, thiab raws li lub sijhawm dhau mus, peb tau txais kev ua haujlwm ntau dua los ntawm cov chaw nres nkoj USB-C li niaj zaus. Qhov kev sib koom ua ke thiab kev tsim qauv no yuav them rau lub sijhawm ntev, thiab txawm hais tias yuav muaj qhov sib txawv ntawm lub sijhawm, cov tuam txhab yuav kawm paub daws lawv cov ntse dua.
Tab sis ib qho uas kuv ib txwm xav tsis thoob yog vim li cas qhov kev sib hloov ntawm lub ntsaws tsis raug tswj los ntawm kev tso cov + thiab - cov xov hlau ntawm sab nraud. Yog li, yog tias lub ntsaws txuas nrog txoj kev "tsis raug", + yuav txuas rau - thiab - yuav txuas nrog +. Tom qab txiav txim siab lub teeb liab ntawm lub receiver, txhua yam koj yuav tsum ua yog thim rov qab cov khoom kom tau txais cov ntaub ntawv raug.
Qhov tseem ceeb, qhov teeb meem yog teeb liab kev ncaj ncees thiab crosstalk. Xav txog hais tias, ib tug 8-pin connector, ob kab ntawm plaub, 1/2/3/4 ntawm ib sab thiab 5/6/7/8 nyob rau lwm yam, qhov twg 1 yog opposite 5. Cia hais tias koj xav tau ib tug khub ntawm +/- txais / tshaj tawm. Koj tuaj yeem sim muab Tx+ rau tus pin 1, Tx- ntawm tus pin 8, Rx+ ntawm tus pin 4, thiab Rx- ntawm tus pin 5. Obviously, ntxig rov qab tsuas yog swaps +/-.
Tab sis lub teeb liab hluav taws xob tsis tau taug kev hla lub teeb liab tus pin, nws taug kev ntawm lub teeb liab thiab nws rov qab los hauv hluav taws xob. Tx-/Rx- yuav tsum yog "rov qab" ntawm Tx + / Rx + (thiab pom tseeb vice versa). Qhov no txhais tau tias Tx thiab Rx teeb liab sib cuam tshuam.
Koj "yuav" sim kho qhov no los ntawm kev ua kom cov teeb liab sib npaug tsis sib npaug - qhov tseem ceeb yog muab lub dav hlau nruj heev nyob ib sab ntawm txhua lub teeb liab. Tab sis nyob rau hauv cov ntaub ntawv no, koj poob qhov sib txawv khub qhov sib txawv-hom suab nrov tiv thaiv, uas txhais tau hais tias yooj yim crosstalk los ntawm Tx + / Rx- opposite ib leeg tsis thim tawm.
Yog tias koj piv qhov no rau kev tso Tx + / Tx- ntawm tus pins 1/2 thiab 7/8 thiab Rx + / Rx- ntawm tus pins 3/4 thiab 5/6 ntawm tus multiplexer, tam sim no lub Tx / Rx teeb liab tsis hla thiab tag nrho crosstalk tshwm sim. ntawm kev sib cuag Tx los yog Rx, yuav ua tau me ntsis rau ob qho tib si thiab ib feem them nyiaj.
(Zoo meej, qhov sib txuas tiag tiag kuj tseem yuav muaj ntau tus pins hauv av, Kuv tsuas yog tsis tau hais txog nws rau qhov kev xav ntawm brevity.)
> Kev sib koom ua ke coj kev sib raug zoo uas nyuaj rau qhia, IMO qhov USB-C nqa tau tsuas yog lub ntiaj teb ntawm kev zais tsis sib xws uas nyuaj rau kev nkag siab rau tech-savvy vim cov specs tsis txawm hais tias nws ua tau / ua tsis tau. thiab nws yuav tsuas yog zuj zus ntxiv raws li ntau hom kev sib txuas ntxiv, thiab cov tib cables muaj teeb meem ib yam nkaus ...
Feem ntau pre-USB-C fais fab connectors yog chim connectors, uas yog ntau pheej yig dua USB-C. Txawm hais tias feem ntau ntawm cov chaw nres tsheb tuaj yeem muaj cov khoom sib txawv txawv uas yog qhov tsis txaus ntseeg, lawv kuj feem ntau muaj kev nkag ncaj qha rau PCI-E thiab lwm lub tsheb npav, thiab feem ntau muaj ntau txoj hauv kev - sai dua USB-C, tsawg kawg yog koj lub sijhawm. ... USB-C tsis yog npau suav phem rau cov neeg nyiag nkas uas tsuas xav tau USB-2, tsuas yog ib qho khoom siv kim, thiab cov khoom sib txuas tsis zoo tagnrho, tab sis thaum koj xav tau txoj hauv kev. Thaum nws los txog rau lub peev xwm siab ceev, USB-C coj nws mus rau lwm qib ntawm kev ua haujlwm.
Tseeb tiag, qhov ntawd yog kuv qhov kev xav thiab. Tus qauv tso cai rau txhua yam, tab sis tsis muaj leej twg yuav siv txhua yam uas yuav ua rau nws nyuaj rau ob qho khoom siv USB-C ua haujlwm ua ke. Kuv twb dhau lawm; Kuv tau siv kuv lub ntsiav tshuaj ntawm USB-A fais fab adapter thiab USB-A rau USB-C cable tau ntau xyoo. Qhov no tso cai rau kuv nqa ib lub adapter rau kuv lub ntsiav tshuaj thiab xov tooj. Yuav ib lub laptop tshiab thiab lub qub adapter yuav tsis them nws - tom qab nyeem cov ntawv dhau los, kuv pom tau hais tias nws yuav xav tau ib qho ntawm cov hluav taws xob ntau dua uas USB-A adapter tsis tuaj yeem muab. Tab sis yog tias koj tsis paub qhov tshwj xeeb ntawm no complex interface, ces nws tsis yog txhua yam meej vim li cas cov qub cable tsis ua haujlwm.
Txawm tias ib tus kws kho mob tsis tuaj yeem ua qhov no. Peb tau txais txhua yam los ntawm Dell hauv chaw ua haujlwm. Dell laptop, Dell docking station (USB3), thiab Dell saib.
Txawm kuv siv qhov chaw nres nkoj twg, kuv tau txais qhov yuam kev "Display connection limit", "Charging limit" yuam kev, tsuas yog ib qho ntawm ob lub vijtsam ua haujlwm, lossis yuav tsis txuas rau qhov chaw nres nkoj txhua. Nws yog ib qho mess.
firmware hloov tshiab yuav tsum tau ua nyob rau hauv lub motherboard, docking chaw nres tsheb, thiab tsav tsheb yuav tsum tau hloov kho. Thaum kawg nws ua rau qhov damn ua haujlwm. USB-C yeej ib txwm mob taub hau.
Kuv siv cov chaw nres tsheb tsis yog Dell thiab txhua yam mus zoo! =D Ua kom zoo USB-C dock tsis zoo li nyuaj - lawv feem ntau ua haujlwm zoo kom txog thaum koj khiav mus rau Thunderbolt oddities, thiab txawm tias tom qab ntawd muaj teeb meem hauv "plug, unplug, ua haujlwm" thaj tsam. Kuv yuav tsis dag, ntawm lub sijhawm no kuv xav pom schematic ntawm motherboard rau Dell laptop nrog cov chaw nres tsheb no.
Arya hais yog lawm. Txhua yam teeb meem ploj mus thaum kuv yuav pheej yig USB-C powered splitter los ntawm Amazon. Keyboards, webcams, USB dongles tuaj yeem ntsaws rau hauv, lub monitor ntsaws rau hauv USB-C, HDMI, lossis DP chaw nres nkoj ntawm lub laptop, thiab nws npaj mus. Kuv tau hais tias yuav ua li cas los ntawm tus txiv neej IT uas hais tias Dell dock tsis tsim nyog cov nyiaj.
Tsis yog, cov no tsuas yog Dell idiots - pom tau tias lawv tau txiav txim siab ua cov khoom lag luam tsis sib xws nrog USB-C thaum siv tib lub txuas.
Yog lawm, yog tias koj nug kuv, ib lub cuab yeej zoo li lub ntsiav tshuaj yuav tsum paub meej ntxiv txog "vim li cas nws tsis them tag nrho". Cov lus pop-up "Tsawg kawg 9V @ 3A USB-C charger yuav tsum tau" yuav daws tau tib neeg cov teeb meem zoo li no thiab ua raws nraim li cov neeg tsim khoom lag luam xav tau. Txawm li cas los xij, peb tsis tuaj yeem ntseeg tias ib qho ntawm lawv yuav tso tawm txawm tias ib qho firmware hloov tshiab tom qab lub cuab yeej mus muag.
Tsis tsuas yog pheej yig dua, tab sis kuj muaj zog dua. Muaj pes tsawg USB connectors tawg koj tau pom ntawm ntau yam khoom siv? Kuv feem ntau ua qhov no - thiab feem ntau xws li cov cuab yeej raug pov tseg, vim tias nws tsis muaj peev xwm kho tau nws ...
USB connectors, pib nrog micro USB, tau flimsy heev, thiab yuav tsum tau txuas mus tas li thiab unplug lawv, feem ntau yog los ntawm cov neeg uas tsis dlhos lawv kom zoo, siv zog ntau dhau, wiggling lawv ntawm ib sab mus rau sab, ua rau cov connectors txaus ntshai. Rau cov ntaub ntawv, qhov no yuav zam tau, tab sis muab hais tias USB-C tam sim no kuj tau siv los ua txhua yam los ntawm smartwatches rau tag nrho cov laptops thiab txhua yam khoom siv hluav taws xob uas tsis siv cov ntaub ntawv txhua, cov khoom sib txuas puas yuav ua ntau dua. . Qhov ntau nws txhawj xeeb rau peb - thiab tsis muaj laj thawj zoo.
Yog lawm, kuv tsuas yog pom ib qho kev sib txuas ntawm lub thoob tawg thiab nws yooj yim heev los kho (ib cag ntawm Dell BS version, nws tsuas yog ua haujlwm ntawm lub charger uas muaj peev xwm sib txuas lus nrog nws, uas zoo nkauj flimsy, koj tuaj yeem ua puas nws txawm tias. koj yeej tsis tau caij tsheb kauj vab..) Txawm tias muaj kev paub txog kev kho tsheb, USB-C txuas yuav yog PITA, nrog ntau thaj chaw PCB, cov pins me me ...
Cov kab txuas txuas feem ntau yog ntsuas rau ib nrab ntawm lub voj voog (lossis tsawg dua) ntawm USB-C txuas li niaj zaus. Qhov no yog vim qhov nruab nrab tus pin flexes txhua zaus nws tso, thiab nrog USB, lub caj npab luv dua. Kuv tau pom ntau lub thoob jacks uas tau raug puas tsuaj los ntawm kev siv.
Ib qho ntawm cov laj thawj USB-C zoo li tsis tshua muaj kev ntseeg siab yog pheej yig connectors lossis cables. Yog tias koj pom cov khoom uas zoo li "stylish" lossis "cooler" nrog kev txhaj tshuaj molding lossis txawm li cas los xij, nws yog qhov tsis zoo. Tsuas yog muaj los ntawm cov tuam txhab loj cable nrog cov lus qhia thiab kos duab.
Lwm qhov laj thawj yog tias koj siv USB-C ntau dua li cov khoom sib txuas. Xov tooj txuas thiab txiav tawm txhua hnub, qee zaum ob peb zaug.
