USB4 2.0 Kaviri Kumhanya, Ramangwana riri Pano
Sezvo PC motherboard vagadziri vanoita40 Gbps USB4, vanhu havagone kuita asi kushamisika kuti chinangwa chinotevera cheiyi chiyero chekubatanidza chepasirese chichava chii? Inozove USB4 2.0, iyo inopa80 Gbpsdata bandwidth munzira imwe neimwe uye 60W simba rekutumira (PD) yekubatanidza. Simba rekutumira USB4 2.0 rinogona kusvika kusvika pa240 W (48 V, 5 A). Pagara paine akawanda mavhezheni e USB, ayo anogona kurondedzerwa seakasiyana. Nekudaro, nekubatanidzwa zvishoma nezvishoma kwemainterfaces, huwandu hweshanduro dze USB hwakadzikira zvakanyanya. Pakazosvika nguva ye USB4, chete USB-C interface yasara. Sei kuchine 2.0 vhezheni? Iyo hombe vhezheni yekuvandudza ye USB4 2.0 kutsigira kwayo kweyero yekufambisa data inosvika makumi masere Gbps, ichipfuura zvachose Thunderbolt 4 interface. Ngationgororei zvakadzama.
Kare, USB4 1.0 yakajairwa yakagadziridzwa zvichibva paThunderbolt 3 tekinoroji, ine huwandu hwepamusoro hwekufambisa data.40 Gbps. Iyo 2.0 vhezheni yakagadziridzwa zvichibva pane nyowani-itsva yemuviri layer yekuvaka, ichiwedzera mwero wekufambisa data kubva panhongonya ye40 Gbps kusvika 80 Gbps, kuseta sirin'i nyowani yekuita ye USB-C ecosystem. Zvinofanira kucherechedzwa kuti chiyero chitsva che80 Gbps chinoda tambo dzinoshanda uye inogona kungotsigirwa nezvimwe zvigadzirwa zvepamusoro mune ramangwana. TheUSB4 2.0data architecture yakagadziridzwa zvakare. Nekuda kweiyo nyowani yemuviri dhizaini yekuvaka yakavakirwa paPAM3 siginecha encoding mechanism uye ichangobva kutsanangurwa 80 Gbps inoshanda data tambo, zvishandiso zvinogona kushandisa zvizere uye zvine musoro kushandisa bandwidth. Iyi update inowedzera kukanganisaUSB 3.2, DisplayPort vhidhiyo kutapurirana, uye PCI Express data chiteshi. Pakutanga, iyo yakanyanya kutamisa mwero we USB 3.2 yaive 20 Gbps (USB3.2 Gen2x2). Pasi peiyo nyowani data architecture, mwero we USB 3.2 uchapfuura 20 Gbps uye usvike pakakwirira kutsanangurwa.
Panyaya yekuenderana, USB4 2.0 ichave kumashure inoenderana ne USB4 1.0, USB 3.2, uye Thunderbolt 3, saka hapana chikonzero chekunetsekana nenyaya dzekuenderana. Pamusoro pezvo, kunakidzwa nechiyero chekufambisa data che80Gbps, nyowani-inoshanda uye inoshandaUSB-C kuenda ku USB-Cdata tambo inodiwa kuti uwane iyi kumhanya. Passive uye inductive USB-C kune USB-C data tambo dzichine yakakura bandwidth ye40Gbps. Kuti ujekese zvirinani zvikamu zvazvino zve USB, iyo USB interface yatanga kubatanidzwa nekuitumidza zvichibva pane yekufambisa bandwidth. Semuenzaniso, USB4 v2.0 inoenderana ne USB 80Gbps, USB4 inoenderanaUSB 40Gbps, USB 3.2 Gen2x2inoenderana ne20Gbps, USB 3.2 Gen2 inoenderanaUSB 10Gbps,uyeUSB 3.2 Gen1inofanana ne USB 5Gbps, nezvimwewo. Mapepa ekuputira, ma-interface labels, uye data cable labels anogona kuonekwa mumufananidzo unotevera.
Muna Gumiguru 2022, USB-IF yakanga yatoburitsa iyo USB4 vhezheni 2.0 yakatarwa, iyo inogona kuwana kutapurirana kuita kwe80 Gbps. Izvo zvinoenderanaUSB Type-CuyeUSB Power Delivery (USB PD)tsanangudzo dzakagadziridzwa zvakare. Pasi peiyo USB4 vhezheni 2.0 kutsanangurwa, iyo USB Type-C chiratidzo chechiratidzo chinogona zvakare kugadzirwa asymmetrically, ichipa kumhanya kwakanyanya kusvika ku120 Gbps mune imwe nzira uchichengetedza kumhanya kwemakumi mana Gbps kune rimwe divi. Parizvino, akawanda epamusoro-ekupedzisira 4K monitors anosarudza kutsigira USB-C imwe-mutsara yekubatanidza yemalaptops. Mushure mekutangwa kwe80 Gbps USB4 2.0 mhinduro, zvimwe4K 144Hzmonitors kana 6K, 8K monitors inogona kubatana nyore kumalaptops kuburikidza ne USB-C. Iyo 80 Gbps USB interface inochengeta USB Type-C chiteshi kuti ive nechokwadi chekuenderana neiripo USB 4 Version 1.0, USB 3.2, USB 2.0 uye Thunderbolt 3. Uyezve, "80 Gbps USB Type-C Data Cable" yakaburitswa mukupera kwegore rino inotsigira yakazara-speed shanduro ye80 Gbps 40W simba re 80 Gbps / 5 (USB PD EPR). Malaptop echizvarwa chitsva anotarisirwa kutangwa mukupera kwegore rino kana gore rinouya anotarisirwa kutanga kutsigira USB 80 Gbps. Kune rimwe divi, epamusoro-simba emitambo maPC uye mamonitor anozokwanisa kushandisa zvirinani kuita kwekadhi yemifananidzo; kune rumwe rutivi, yekunze yakasimba-nyika PCIe inogonawo kumhanya kusvika kuzere.
