Ujongano lweLVDS (Low Voltage Differential Signaling) bubuchwephesha bonxibelelwano lwedijithali obuyilelwe-ukuhanjiswa kwedatha ngesantya esiphezulu phakathi kwezixhobo zombane ngenjongo yokunciphisa ukusetyenziswa kwamandla kunye nokuphazamiseka kombane wombane (EMI). Isetyenziswa rhoqo kwizicelo ezifuna ugqithiso lwedatha oluthembekileyo, oluphezulu{2}}luphezulu, kuquka izikrini zeLCD, iilaptops, iziboniso zemoto, kunye nezixhobo zefektri.
Iimpawu eziphambili ze-LVDS ziquka:
Ukusebenza koMbane ophantsi: I-LVDS isebenza kumbane ophantsi, ngokuqhelekileyo ukusuka kwi-1.2 ukuya kwi-1.8 volts, ekhokelela ekunciphiseni ukusetyenziswa kwamandla kunye nokuveliswa kobushushu.
Umqondiso owahlukileyo: Idatha idluliswa kusetyenziswa izibini ezihlukeneyo, apho ucingo olunye luthwala umqondiso wokuqala kwaye enye ithwala isignali eguqulweyo. Le ndlela inceda ukucima ingxolo kwaye inciphisa i-EMI.
Phezulu-Ugqithiso lweDatha ngesantya esiphezulu: I-LVDS isekela amanani aphezulu edatha, ngokuqhelekileyo ukuya kwiigigabhithi ezininzi ngesekhondi, okwenza ukuba ifaneleke kwizicelo ezifuna ukuhanjiswa kwedatha ngokukhawuleza.
ICable ende iyabaleka: Ngenxa ye-EMI ephantsi kunye nokwahluka komqondiso, i-LVDS inokudlulisa idatha ngokuthembekileyo kumgama omde xa kuthelekiswa nenye-indlela egqityiweyo yokubonisa.
Amatshaneli amaninzi: I-LVDS inokuxhasa amajelo amaninzi osasazo lwedatha ngaxeshanye, iyenze ilungele-iziboniso eziphezulu ezifuna amanani amakhulu edatha ukuba ahanjiswe ngokukhawuleza.
Izibonelelo zeLVDS zezi:
Ukusetyenziswa kwamandla aphantsi: Ukusebenza kwamandla ombane asezantsi e-LVDS kukhokelela ekucuthekeni kosetyenziso lwamandla, okuluncedo kwizixhobo-ezinebhetri kunye nezicelo apho usebenziso lwamandla lubalulekile.
UkuNciphiswa koMbane woMbane (EMI): Ukubonakaliswa okungafaniyo kunceda ukukhansela ingxolo kunye nokunciphisa i-EMI, ukuphucula imfezeko yesignali kunye nokunciphisa ukuphazamiseka kwezinye izixhobo zombane.
Amaxabiso aphezulu okuDlulisa iiNkcukacha: I-LVDS inokusingatha amazinga aphezulu edatha, iyenze ifaneleke kwizicelo ezifuna ukuhanjiswa kwedatha ngokukhawuleza nokuthembekileyo, okufana neziboniso ze-HD kunye-noqhagamshelwano oluphezulu lwedatha.
Ugqithiso lweDatha eLude: Ukukwazi ukuhambisa idatha ngokuthembekileyo kwimigama emide ngaphandle kokuthotywa komqondiso obalulekileyo yeyona nto iphambili ye-LVDS.
Nangona kunjalo, i-LVDS nayo ineziphene zayo:
Ukuntsonkotha: I-LVDS idinga izibini ezihlukeneyo kwisignali nganye, enokuthi idibanise ukuyila kunye nokwandisa inani leengcingo ezifunekayo ukuhanjiswa kwedatha.
Iindleko: Ukusebenzisa i-LVDS kunokubiza kakhulu ngenxa yesidingo samacandelo awongezelelweyo kunye ne-cabling enzima ngakumbi.
I-LVDS isetyenziswa kakhulu kwizicelo ezifuna-isantya esiphezulu, ugqithiso oluthembekileyo lwedatha. Iqhele ukufunyanwa kwizikrini ze-LCD kunye neziboniso zeelaptops, iimonitha, kunye nomabonakude, apho ithumela ngokufanelekileyo idatha yevidiyo. Kwimiboniso yeemoto, i-LVDS iqinisekisa uphazamiseko oluncinci lweenkqubo zolwazi, imiboniso yedeshibhodi, kunye{3}}neekhamera zokujonga ngasemva. Ikwasetyenziswa kwizixhobo zemizi-mveliso kwiiphaneli zolawulo kunye neemonitha, kwiikhamera{5}}ezinokulungiswa okuphezulu kunye nezixhobo zokujonga ukuhanjiswa kwedatha okukhawulezayo, nakuthungelwano lonxibelelwano kunye nezixhobo zonxibelelwano apho idatha{6}}ekhawulezayo ibalulekile.
