Kev txhim kho theem tom ntej ntawm USB thev naus laus zis yog USB4, uas muab 40Gbit / sec cov ntaub ntawv xa mus ceev, yog sib xws nrog Thunderbolt 3, thiab tsuas yog siv USB-C interface. Cov lus qhia tshiab PD ntawm USB Hom-C Spec R2.1 txhawb nqa txog 240W (48V / 5A). ) Them fais fab / P (lub zog)=U (voltage) × I (tam sim no). USB-C 240W PD tuaj yeem muab lub zog ntau dua rau cov saib loj, tshuab luam ntawv thiab qee lub khoos phis tawj desktop. Txawm li cas los xij, yog tias koj xav txhawb 240W PD, koj xav tau USB-C cable tshiab. Lub 240W PD USB-C cable disassembly yuav raug tso tawm tag kis, thiab cov cable yuav tsum muaj lub logo tshwj xeeb rau cov neeg siv khoom kom paub qhov txawv. USB4 yog tsim los ua kom muaj bandwidth thiab tsom mus rau npog lub USB-C interface ecosystem thiab txo qhov tsis meej pem rau cov neeg siv kawg.
Ntau qhov tseem ceeb tsim ntawm USB4 suav nrog:
Siv ib qho USB-C interface kom paub cov zaub, cov ntaub ntawv thiab thauj khoom / khaws cia ua haujlwm
Universally sib xws nrog cov khoom uas twb muaj lawm USB thiab Thunderbolt
Txhais qhov chaw nres nkoj ua haujlwm kom ua tiav qhov kev xav tau thiab cov neeg siv kev paub zoo ib yam
Cia tus tswv tsev hloov kho kom yooj yim teeb tsa bandwidth, tswj fais fab thiab lwm yam kev ua haujlwm cuam tshuam raws li qhov system yuav tsum tau ua
Txij li thaum nws pib, USB thev naus laus zis tau ua tiav zoo thiab yuav txuas ntxiv mus rau yav tom ntej. Rau USB 3.1 Gen 1 thiab Gen 2, qhov sib txawv tsuas yog ceev, lawv ob leeg rov qab sib xws nrog USB 3.0 thiab USB 2.0. Nyob rau hauv lub neej yav tom ntej, nrog rau kev tso tawm ib tiam tshiab ntawm USB cov qauv thiab USB-C, USB yuav tsum tau txhim kho ntxiv.
