Dab tsi yog USB4 Tshiab?

 

Ob tusUSB 3.1thiabUSB 3.2tau qhia kom nce bandwidth, thiab cov hom phiaj tsim qauv ntawmUSB4nyob twj ywm tsis hloov. Txawm li cas los xij, kev tso tawm ntawm qhov tshwj xeeb no tseem yog qhov sib sau ua keUSB hom-Cecology thiab txo cov kev tsis meej pem ntawm cov neeg siv kawg.

 

Txawm hais tias USB4 tus txheej txheem tshiab qhia txog txheej txheem txheej txheem tshiab, nws tseem tau sib xws nrog USB3.2, USB2.0 thiab Thunderbolt 3. USB4 yuav txais yuav ob txoj hauv kev ua ob txoj kab ke yooj yim architecture, uas ob zaug kev xa xov kis ntawm cov hom-C , nrog kev sib kis ntawm tsawg kawg 20Gbps thiab xaiv 40Gbps. Qhov xa tawm ntau tshaj plaws yog ob zaug ntawm cov dhau los USB 3.2. Txog kev sib tshuam thiab cov txuas hluav taws xob Ob lub cav sib txawv yuav tau muab. Rau40GbpsUSB4, txheej txheem encoding tseem 128b / 132b siv los ntawm USB 3.2, thaum 20Gbps yuav siv 64b / 66b. Qhov chaw USB4 muab tsawg kawg 7.5W ntawm lub zog (5V, 1.5A) rau ib qho chaw nres nkoj.

 

Ib qho ntxiv,USB4 ntxiv qhov kev txhawb nqa kom txhawb nqa PCie thiab DisplayPort1.4a, yog li ua tiav ntau txheej txheem kev ua haujlwm ntawm ib qho kev sib txuas ntawm lub cev. Brad Saunders taw qhia tias feem ntau cov koos pij tawj nruab nrog USB4 yuav tau sib haum nrog Thunderbolt 3, tab sis rau cov tuam txhab xov tooj ntawm tes, qhov kev txhawb nqa no yuav tsum tsis txhob ntxiv. Raws li rau kev them nyiaj yug software, nws paub tias Linux 5.6 system twb txhawb USB4, thiab USB4 tus tsav tsheb rau Microsoft Windows tau hais tias tseem tab tom tsim kho.

Cypress announced in March 2020 the Type-C controllers for next-generation desktop and mobile computers, EZ-PD CCG6DF and EZ-PD CCG6SF. Ob tuscontrollers are single-chip solutions and are compatible with USB 3.2/4.

CCG6DF / CCG6SF txhawb nqa ob lub luag haujlwm ntawm chaw nres nkoj (DRP) thiab yuav txhawb nqa tag nrhoPD3.0cov lus qhia tshwj xeeb. Qhov kev zov me nyuam muaj 64KB ntawm flash cia thiab 96KB ntawm ROM cia, thiab txhawb kev poob qis-nyab xeeb pib thiab firmware hloov khoom dua tshiab.
