Cov xov hlau USB
USB, lub npe luv ntawm Universal Serial BUS, yog tus qauv tsheb npav sab nraud, siv los tswj kev sib txuas thiab kev sib txuas lus ntawm cov khoos phis tawj thiab cov khoom siv sab nraud. Nws yog ib qho thev naus laus zis siv hauv PC teb.
USB muaj qhov zoo ntawm kev xa xov ceev (USB1.1 yog 12Mbps, USB2.0 yog 480Mbps, USB3.0 yog 5Gbps, USB3.1 yog 10Gbps, USB3.2 yog 20Gbps), USB cable yooj yim siv, txhawb kev sib pauv kub, kev sib txuas yooj ywm, kev muab hluav taws xob ywj pheej, thiab lwm yam. Nws tuaj yeem txuas nas, keyboard, tshuab luam ntawv, scanner, koob yees duab, flash disk, MP3 player, xov tooj ntawm tes, koob yees duab digital, mobile hard disk, external optical floppy drive, USB card, ADSL Modem, CableModem, thiab yuav luag txhua yam khoom siv sab nraud.
Lub ntsiab lus ntawm USB 1.0/2.0/3.0
USB 1.0/1.1
Lub Rooj Sab Laj USB Implement (USB Implement Forum) tau muab tso tawm thawj zaug xyoo 1995 los ntawm xya lub tuam txhab suav nrog Intel, IBM, Compaq, Microsoft, NEC, Digital, North Telecom, thiab lwm yam. Lub koom haum USBIF tau tshaj tawm cov lus qhia USB1.0 thaum Lub Ib Hlis 1996, nrog rau bandwidth ntawm 1.5Mbps. Txawm li cas los xij, vim tias thaum lub sijhawm ntawd kev txhawb nqa USB peripheral devices muaj tsawg, yog li cov lag luam host board tsis muab USB Port tsim ncaj qha rau ntawm host board.
USB 2.0
Cov lus qhia USB2.0 tau tsim thiab luam tawm los ntawm Compaq, Hewlett Packard, Intel, Lucent, Microsoft, NEC, thiab Philips. Cov lus qhia no ua rau qhov ceev ntawm kev xa cov ntaub ntawv ntawm cov khoom siv peripheral nce mus txog 480Mbps, uas yog 40 npaug sai dua li USB 1.1. Tus qauv USB 2.0, tsim muaj xyoo 2000, yog USB 2.0 tiag tiag. Nws hu ua High speed version ntawm USB 2.0, nrog rau qhov ceev ntawm kev xa mus rau theoretical ntawm 480 Mbps.
USB 3.0
USB3.0 yog qhov tseeb tshaj plaws ntawm USB, uas tau pib los ntawm Intel thiab lwm lub tuam txhab. Qhov siab tshaj plaws ntawm kev xa xov ntawm USB3.0 yog txog li 5.0Gbps (640MB / s). Usb 3.0 qhia txog kev xa cov ntaub ntawv puv-duplex. USB 3.0 tso cai rau kev nyeem thiab sau ua haujlwm synchronous thiab puv-ceev.
USB Hom A: Tus qauv no feem ntau siv tau rau cov khoos phis tawj tus kheej, PCS, yog tus qauv interface siv dav tshaj plaws
USB Hom B: Feem ntau siv rau kev txuas 3.5-nti portable hard disks, printers, thiab monitors
Mini-USB: Feem ntau siv rau cov koob yees duab digital, cov koob yees duab digital, cov cuab yeej ntsuas thiab cov hard disks mobile thiab lwm yam khoom siv mobile
Micro USB: Micro USB chaw nres nkoj, tsim nyog rau cov khoom siv mobile
Thaum ntxov ntawm lub xov tooj ntse, peb siv Micro-USB interface raws li USB 2.0 feem ntau, uas yog, USB data cable interface ntawm lub xov tooj ntawm tes. Tam sim no, lawv tau pib nkag mus rau hom TYPE-C interface. Yog tias muaj cov kev cai xa cov ntaub ntawv siab dua, lawv yuav tsum tau hloov mus rau version 3.2 lossis siab dua, tshwj xeeb tshaj yog nyob rau hauv lub hnub nyoog niaj hnub thaum cov lus qhia interface lub cev tau hloov kho tshiab. Nrog USB-C, lub hom phiaj yog los tswj lub ntiaj teb. Ua ntej Thunderbolt™ ntawm qhov ceev ceev, thiab tsis ntev los no nrog USB4, lub hom phiaj yog los tswj lub ntiaj teb los ntawm qhov kawg qis mus rau qhov kawg siab. Thunderbolt™ interface, uas yav dhau los tau txwv los ntawm INTEL cov nqi patent, tam sim no pub dawb rau daim ntawv tso cai, uas yuav pab nthuav kev lag luam rau nws lub interface. Intel tau tshaj tawm daim ntawv tso cai dawb rau Thunderbolt™ interface! Tej zaum Thunderbolt 3 lub caij nplooj ntoos hlav yuav los txog rau xyoo 2018! Ntau yam chaw nres nkoj tuaj yeem hloov los ntawm USB Hom C chaw nres nkoj uas txhawb nqa Thunderbolt 3.
USB Hom-C muaj cov yam ntxwv hauv qab no
Nws sib xws nrog cov lus qhia txuas ntawm USB 2.0, 3.0 yav dhau los thiab yav tom ntej USB specifications, txhawb nqa 10,000 plugging thiab unplugging, thiab txhawb nqa kev them ntawm 3C cov khoom (yog tias xav tau kev ua haujlwm ntawm tam sim no siab tsim los ntawm USB 3.1PD, nws yog qhov tsim nyog siv Hom C thiab cov xov hlau tshwj xeeb. Hom A / B thawj tsis tuaj yeem ua tiav), USB interface (Hom A, B, thiab lwm yam) uas tib neeg tham txog hauv lub neej txhua hnub thiab USB Hom C interface uas yuav thoob ntiaj teb yav tom ntej koom nrog cov lus qhia lub cev ntawm lub interface, thiab USB2.0, USB3.0, USB3.1, thiab lwm yam, yog cov txheej txheem sib txuas lus cuam tshuam.
USB Hom-C Qhov no yog qhov kev qhia tshwj xeeb tshiab ntawm USB association, USB Hom-C vim nws tau luam tawm nrog USB3.1, yog li ntau tus neeg yuam kev rau USB Hom-C 3.1 yuav tsum siv kev sib txuas xov hlau ntawm USB Hom-C, tuaj yeem ua tiav qhov kev ua tau zoo ntawm 10Gb / s, Qee tus neeg sau USB Hom-C ua USB3.1 Hom-C, uas tsis yog lawm.
Cov kab txuas sib txuas tib yam siv tau rau hauv USB3.0 thiab USB3.1, yog li ntawd, kev ua tau zoo 10Gb/s tib yam siv tau los ntawm kev siv cov kab xa xov USB3.0. Cia peb saib cov lus qhia hauv qab no:
Tau kawg, qhov ceev ntawm cov xov hlau zoo dua qhov yuav tsum tau ua, thaum koj siv cov khoom USB3.1, thov sim siv cov xov hlau uas muab los ntawm lub chaw tsim khoom loj dua, kom tsis txhob siv cov xov hlau tsis zoo, ua rau kev ua haujlwm tsis tuaj yeem txhim kho qhov xwm txheej, Tshwj xeeb tshaj yog qee cov khoom HUB ua haujlwm tag nrho (Dongguan Jingda Electronics Co., Ltd.)
https://www.jd-cables.com.
3.1 cov lus qhia ntawm GEN2 high-speed hlau tuaj yeem pom zoo rau kev siv, ntawm chav kawm, ntau dua tuaj yeem xa mus rau peb cov ntaub ntawv xa khoom: High frequency hlau ntau lawm khoom xa tuaj】), USB Hom-C connector (connector) kuj tuaj yeem siv rau hauv USB3.0, USB 2.0 kev sib txuas kis, tau siv rau hauv ntau yam khoom, xws li xov tooj ntawm tes, ntsiav tshuaj, thiab lwm yam.
