Cov kev qhia tshwj xeeb ua ntej Hom C (TypeA, TypeB, thiab lwm yam) tau tsom mus rau "nyuaj" cov yam ntxwv ntawm USB interface, xws li tus naj npawb ntawm cov cim, cov duab ntawm lub interface, cov yam ntxwv hluav taws xob, thiab lwm yam.TypeC ntxiv qee cov ntsiab lus "mos" raws li kev txhais cov "nyuaj" yam ntxwv ntawm USB interface.USB interface (tsuas yog hais txog TypeC) tau tshem tawm ntawm kev koom tes nrog USB thiab dhau los ua qhov tshwj xeeb tshiab uas tuaj yeem ua tau raws li USB specification.Tom qab USB tau hloov kho mus rau version 3.1, lub cev sib cuam tshuam tag nrho txais yuav hom C qauv, thiab qhov tseeb 3.1 tus qauv USB Hom-C hlau qauv tsis zoo li qub, uas ua rau muaj kev kub ntxhov ntau.Txog rau xyoo 2019, txhawm rau ua qauv rau lawv Rau kev ua haujlwm thiab kev ua haujlwm hluav taws xob, lub koom haum tau teeb tsa qhov pib.Yog tias ib qho khoom xav txhawb nqa 5A siab tam sim no, USB 3.0 lossis siab dua kev sib kis ceev thiab cov yeeb yaj kiab tso tawm, nws yuav tsum tau nruab nrog E-Marker nti.E-kos npe, tag nrho lub npe: Electronically Marked Cable, USB Type-C active cable ntim nrog E-Marker nti, DFP thiab UFP tuaj yeem siv PD raws tu qauv los nyeem cov khoom ntawm cov cable, suav nrog lub peev xwm xa hluav taws xob, cov ntaub ntawv xa mus, ID Tos rau cov ntaub ntawv, yooj yim hais, yog hais tias tus Type-C cov ntaub ntawv cable muaj ib tug E-Marker nti (peb hu nws ib tug hluav taws xob daim ntawv lo), E-Marker (Electronically Marked Cable) kuj yooj yim to taub raws li ib tug hluav taws xob daim ntawv lo rau hom-C. kab.Cov txheej txheem ua haujlwm ntawm lub cable tuaj yeem nyeem tau los ntawm E-Marker nti, xws li kev xa hluav taws xob, kev xa cov ntaub ntawv, kev sib kis video thiab ID.Raws li qhov no, qhov tso zis davhlau ya nyob twg tuaj yeem kho qhov sib txuam voltage / tam sim no lossis lub suab thiab cov teeb liab video raws li cov khoom siv txuas nrog xws li xov tooj ntawm tes lossis saib.Yav dhau los, E-Marker chips yeej ib txwm raug xa tawm.Cypress (Cypress) thiab Intel muaj zog E-Marker nti khoom.Apple ib zaug kho lub E-Marker USB 4 nti JHL 7040 los ntawm Intel los siv rau ntawm Thunderbolt interface.Nyob rau hauv xyoo tas los no, chips uas tuaj yeem txhawb nqa hauv tsev E-tshuaj kuj tau pib ua lag luam hauv cov khoom siv thiab dhau los ua cov ntsiab lus tseem ceeb.
| Qee cov qauv E-Marker cov khoom lag luam uas txhawb USB4 tau raug tso tawm | |
| Hom Lub Npe | Chip Model |
| Cypress | PEB 2103 |
| Intel | JHL7040 |
| VIA Labs | lwv 153 |
| ConvenientPower Semiconducto | CP8821 |
| INJOINIC | IP2133 |
Thawj lub hauv paus ntsiab lus ntawm kev siv E-kos npe: Yog tias koj xav muab qhov hluav taws xob ntau tshaj 5V lossis tam sim no tshaj 3A los ntawm USB TYPE-C interface, ces koj yuav tsum xav tau TYPE-C interface nti los siv USB PD raws tu qauv.
Lub hauv paus ntsiab lus thib ob ntawm kev siv E-kos: Yog tias koj lub cuab yeej siv 5V voltage, thiab tam sim no tsis tshaj 3A.Nws nyob ntawm tus yam ntxwv ntawm cov khoom siv hluav taws xob thiab cov ntaub ntawv kis tus yam ntxwv ntawm lub cuab yeej nws tus kheej.Yog tias lub cuab yeej nws tus kheej tsuas yog muab lub zog rau sab nraud, lossis tsuas yog lees txais lub zog los ntawm lwm tus neeg sab nraud, thiab lub luag haujlwm ntawm lub zog thiab cov ntaub ntawv xa tawm tau raug sib luag los ntawm lub neej ntawd (uas yog, lub hwj huam mov yog HOST, thiab cov neeg siv hluav taws xob yog qhev. los yog ntaus ntawv), ces koj tsis xav tau TYPE-C nti.
Lub hauv paus ntsiab lus thib peb ntawm kev siv E-kos: Ob lub hauv paus ntsiab lus no yog siv los txiav txim seb puas xav tau TYPE-C nti ntawm lub cuab yeej.Lwm lub ntsiab lus uas tau nyiam ntau yam yog seb puas yuav tsum muaj E-MARKER nti ntawm CC kis kab mob.Qhov kev txiav txim siab no yog cov txheej txheem siv, puas yuav dhau 3A?Yog tias nws tsis tshaj, koj tsis xav tau.Txoj kab A rau C, B rau C yog nyob ntawm seb koj yuav tsum tau ua raws li Txoj Cai Them Nqi Roj Teeb.Yog tias koj xav siv nws, koj tuaj yeem siv LDR6013.Qhov zoo dua yog tias nws tuaj yeem paub ob qho tib si them thiab them nyiaj.Hloov cov ntaub ntawv kom tsis txhob muaj teeb meem uas qee cov adapters uas tsis ua raws li Txoj Cai Lij Choj Battery Charging tsis tuaj yeem them Apple li.
