GMSL2 cable VS GMSL3 cable

Ob leeg GMSL2 thiab GMSL3 cables yog coaxial cables siv los txhawb high-bandwidth video thiab cov ntaub ntawv kis tau tus mob. Qhov sib txawv tseem ceeb yog nyob rau hauv cov kev txhawb nqa raws tu qauv thiab cov kev xav tau ntawm kev ua haujlwm. Nov yog qhov sib piv:

1. Cov ntaub ntawv tus nqi thiab kev daws teeb meem txhawb nqa

GMSL2 kab

Cov ntaub ntawv tus nqi: Txhawb cov ntaub ntawv tus nqi mus txog 6 Gbit / s.
Kev them nyiaj yug kev daws teeb meem: Txhawb lub koob yees duab txog li 8 megapixels, thiab txhawb nqa 4K daws teeb meem qhia thiab cov kwj video los ntawm Display Stream Compression (DSC) thev naus laus zis.
Daim ntawv thov: Tsim nyog rau kev xa cov ntaub ntawv lub koob yees duab siab daws teeb meem, lossis 4K tso saib video ntws.

GMSL3 kab

Cov ntaub ntawv tus nqi: Txhawb kev txuas txuas mus txog 12 Gbit / s, uas yog ob zaug ntawm GMSL2.
Kev them nyiaj yug kev daws teeb meem: Feem ntau txhawb ntau channel 4K daws teeb meem video kwj kis, thiab tuaj yeem daisy-chain ntau cov lus qhia thiab lub koob yees duab.
Daim Ntawv Thov: Tsim los rau cov xwm txheej uas yuav tsum tau muaj kev sib koom ua ke ntawm ntau cov channel video, xws li ADAS (Advanced Driver Assistance System), cov koob yees duab nyob ib puag ncig, thiab daisy-chain sib txuas rau cov khoom hauv tsheb.

2. Cable yuav tsum tau thiab tsis

Hom kab ntau lawm

GMSL2 thiab GMSL3 systems feem ntau siv cov coaxial shielded cables (xws li RTK031, thiab lwm yam) los yog twisted khub los xa cov teeb liab.
Fakra lossis HSD connectors feem ntau yog siv rau hauv cov tshuab no kom ntseeg tau tias muaj kev ntseeg siab thiab tiv thaiv kev cuam tshuam ntawm cov teeb liab ntau zaus.

Kev sib kis nrug:

GMSL2 Cable: Ntawm tus qauv shielded coaxial cable, qhov kis tau tus mob yog feem ntau 15 mus rau 20 meters, nyob ntawm seb hom cable thiab kis tus nqi.
GMSL3 Cable: Vim yog lub teeb liab siab dua, qhov kev sib kis ntawm qhov deb feem ntau yog 10 mus rau 15 meters, thiab cov khoom siv hluav taws xob zoo thiab cov khoom sib txuas tuaj yeem txuas ntxiv mus.

3. Cov yam ntxwv tseem ceeb thiab cov txiaj ntsig

GMSL 2

Muab compressed thiab uncompressed video cov ntaub ntawv kis tau tus mob.
Txhawb Ethernet tunneling, tso cai Ethernet cov ntaub ntawv kis tau tus mob hla ib kab (txog 1.5 Gbit / s rov qab channel tus nqi).
Haum rau mainstream automotive systems nrog high-resolution ib lub koob yees duab thiab cov lus qhia.

GMSL 3

Txhim kho ntau lub cuab yeej sib sau ua ke, tso cai rau cov kwj tawm video los ntawm ntau lub koob yees duab lossis cov lus qhia kom kis tau tus kab mob ib zaug.
Txhawb nqa cov ntaub ntawv ntau dua thiab ntau cov txheej txheem kev ua haujlwm nyuaj, xws li ntau-channel 4K tso saib video kwj.
Muab cov kev daws teeb meem zoo tshaj plaws rau ntau lub sensor thiab tso saib kev sib txuas hauv cov tsheb tsis muaj zog.

4. Keeb kwm thiab evolution ntawm GMSL

GMSL (2008): txhawb nqa 3.125 Gbit / s rau kev xa cov lus qhia siab lossis lub koob yees duab yees duab ntws.
GMSL2 (2018): txhawb nqa 6 Gbit / s thiab ntxiv cov duab kwj compression thiab Ethernet tunneling ua haujlwm.
GMSL3 (2021): txhawb nqa 12 Gbit / s, optimizes ntau cov khoom sib sau ua ke, daisy saw txuas, thiab txhim kho kev ua haujlwm yooj yim.
