HDMI2.1 connector technology txhais lus

Lub HDMI 2.1 txuas tau pom ntau yam hloov tshiab hauv hluav taws xob thiab lub cev ua haujlwm tsis zoo piv rau HDMI 1.4 version. Wb delve rau hauv txhua qhov hloov tshiab no:

1 、 Kev Ntsuas Siab Tshaj Lij rau HDMI Connectors:

Raws li qhov kev thov rau cov ntaub ntawv siab kis tau tus mob, tshwj xeeb tshaj yog rau 4K thiab 8K Ultra HD (UHD) TVs, nce, HDMI ua qhov tseem ceeb rau kev txhim kho cov ntaub ntawv hloov chaw ntawm qhov chaw (video player) thiab tus txais (TV). Nrog rau cov ntaub ntawv ntau dua, kev sib tshuam ntawm cov khoom siv no dhau los ua ib qho kev cuam tshuam rau kev xa cov ntaub ntawv txhim khu kev qha. Qhov kev sib cuam tshuam no yuav ua rau muaj teeb meem kev ntseeg siab (SI) xws li Electromagnetic Interference (EMI), crosstalk, Inter-Symbol Interference (ISI), thiab teeb liab jitter. Yog li ntawd, nrog kev nce hauv cov ntaub ntawv tus nqi, HDMI 2.1 connector tsim tau pib xav txog SI. Raws li qhov tshwm sim, lub koom haum kuaj tau ntxiv cov kev xav tau rau kev ntsuas siab. Txhawm rau txhim kho SI kev ua tau zoo ntawm HDMI connectors, connector manufacturers tau hloov kho cov duab ntawm cov hlau pins thiab dielectric cov ntaub ntawv raws li kev cai tsim thiab cov neeg kho tshuab kev ntseeg tau kom tau raws li qhov yuav tsum tau ntawm high-frequency xeem.

2, Ntxiv Bandwidth Requirements rau HDMI 2.1 Connectors:

Lub HDMI 2.0 yav dhau los muaj kev nkag mus ntawm 18Gbps tab sis tsis tau txhais cov HDMI cables tshiab lossis cov khoom sib txuas. HDMI 2.1, ntawm qhov tod tes, khav theeb dhau ob npaug ntawm qhov kev xa tawm, tso cai rau bandwidths txog li 48 Gbps. Thaum tshiab HDMI 2.1 cables yuav rov qab tau tshaj HDMI 1.4 thiab HDMI 2.0 cov khoom siv, cov cables qub yuav tsis ua rau pem hauv ntej-tshaj nrog cov lus qhia tshiab. HDMI 2.1 connectors muaj plaub cov ntaub ntawv raws: D2, D1, D0, thiab CK, los ntawm cov ntaub ntawv xa tawm txawv. Raws li txhua lub channel qhia cov yam ntxwv hluav taws xob zoo sib xws, HDMI 2.1 connector tsim yuav tsum tau ua kom pom kev ua tau zoo tshaj SI kom tau raws li 48Gbps bandwidth ntawm lwm tiam HDMI connector.

3 、 Ntxiv qhov yuav tsum tau sib txawv:

HDMI 2.1 connector tester poob rau qeb 3, hos HDMI 1.4 kev ntsuam xyuas poob rau hauv qeb 1 thiab qeb 2. Tom qab HDMI 2.1, connector duab raug txwv rau hom A, C, thiab D, nrog rau yav dhau los-siv hom E interface feem ntau nyob rau hauv lub tsheb. teb tau phased tawm. Txhawm rau txhim kho cov yam ntxwv hluav taws xob kom ua tau raws li HDMI 2.1 cov qauv, cov qauv txuas txuas yuav tsum tau hloov kho cov qauv tsim xws li qhov dav, tuab, thiab ntev ntawm cov hlau pins. Qee cov tuam txhab lag luam kuj tseem siv lwm txoj hauv kev, xws li qhia qhov tsis sib xws hauv lub qhov (socket) cov khoom siv hluav taws xob, kom txo qis kev sib txuas. Thaum kawg, cov kev tsim qauv tsim nyog yuav tsum tau ua kom tau raws li qhov ntsuas impedance. HDMI 2.1 connectors muab SI kev ua tau zoo dua li yav dhau los cov qib qis dua, thiab cov tuam txhab txuas sib txuas yuav siv ntau yam cuab yeej thiab cov txheej txheem tswj.
