Kev txhais lus thev naus laus zis ntawm HDMI2.1 connector
Lub Hdmi 2.1 qhov txuas tau pom ntau qhov hloov tshiab hauv kev ua haujlwm hluav taws xob thiab lub cev piv rau HDMI 1.4 version. Cia peb kawm txog txhua qhov kev hloov tshiab no:
1、Kev Ntsuas Zaus Siab Ntau Ntxiv rau HDMI Connectors:
Raws li qhov kev thov rau kev xa cov ntaub ntawv siab, tshwj xeeb tshaj yog rau 4K thiab 8K Ultra HD (UHD) TVs, nce siab, HDMI ua qhov tseem ceeb rau kev xa cov ntaub ntawv txhim khu kev qha ntawm qhov chaw (video player) thiab lub receiver (TV). Nrog rau cov ntaub ntawv siab dua, qhov kev sib txuas ntawm cov khoom siv no ua rau muaj kev cuam tshuam rau kev xa cov ntaub ntawv txhim khu kev qha. Qhov kev sib txuas no yuav ua rau muaj teeb meem Signal Integrity (SI) xws li Electromagnetic Interference (EMI), crosstalk, Inter-Symbol Interference (ISI), thiab teeb liab jitter. Yog li ntawd, nrog rau kev nce ntxiv ntawm cov ntaub ntawv, HDMI 2.1 connector tsim tau pib xav txog SI. Yog li ntawd, kev sim kev koom tes tau ntxiv cov kev cai rau kev sim siab zaus. Txhawm rau txhim kho kev ua tau zoo SI ntawm HDMI connectors, cov chaw tsim khoom connector tau hloov kho cov duab ntawm cov hlau pins thiab cov ntaub ntawv dielectric raws li cov cai tsim thiab kev ntseeg siab ntawm cov khoom siv kom ua tau raws li cov kev cai sim siab zaus.
2、Cov Kev Xav Tau Bandwidth Ntxiv Rau HDMI 2.1 Cov Khoom Txuas:
HDMI 2.0 yav dhau los muaj qhov throughput ntawm 18Gbps tab sis tsis tau txhais cov tshiab Hdmi Cables lossis cov khoom sib txuas. HDMI 2.1, ntawm qhov tod tes, khav theeb ntau dua ob npaug ntawm qhov throughput, tso cai rau bandwidths txog li 48 Gbps. Thaum cov HDMI 2.1 cables tshiab yuav rov qab sib xws nrog HDMI 1.4 thiab HDMI 2.0 li, cov cables qub yuav tsis sib xws nrog cov lus qhia tshiab. HDMI 2.1 connectors muaj plaub cov ntaub ntawv channel: D2, D1, D0, thiab CK, uas cov ntaub ntawv raug xa mus sib txawv. Raws li txhua channel sib koom cov yam ntxwv hluav taws xob zoo sib xws, HDMI 2.1 connector tsim yuav tsum ua kom pom kev ua tau zoo SI zoo dua kom tau raws li 48Gbps bandwidth ntawm HDMI connector tiam tom ntej.
3, Cov Kev Cai Sib Txawv Ntxiv:
Kev kuaj HDMI 2.1 connector poob rau hauv Qeb 3, thaum kev kuaj HDMI 1.4 poob rau hauv Qeb 1 thiab Qeb 2. Tom qab HDMI 2.1, cov duab ntawm connector tsuas yog txwv rau Hom A, C, thiab D, nrog rau Hom E interface uas siv yav dhau los feem ntau hauv kev lag luam tsheb raug tshem tawm. Txhawm rau txhim kho cov yam ntxwv hluav taws xob kom ua tau raws li HDMI 2.1 cov qauv, cov qauv tsim connector xav tau kev hloov kho rau cov qauv tsim xws li qhov dav, tuab, thiab ntev ntawm cov hlau pins. Qee cov chaw tsim khoom kuj tseem yuav siv lwm txoj hauv kev, xws li kev qhia txog qhov sib txawv hauv cov khoom siv dielectric ntawm lub qhov (socket), kom txo qhov kev sib txuas capacitance. Thaum kawg, cov qauv tsim uas tau lees paub yuav tsum ua tau raws li cov qib impedance. HDMI 2.1 connectors muab kev ua tau zoo SI zoo dua li cov qauv qis dua yav dhau los, thiab cov chaw tsim khoom sib txuas yuav siv ntau yam khoom siv thiab cov txheej txheem tswj.
