USB4 2.0 Kumhanya kwakapetwa kaviri, Ramangwana rasvika
Sezvo vagadziri vePC motherboard vachiisa40 Gbps USB4, vanhu havagoni kurega kushamisika kuti chinangwa chinotevera cheiyi standard yekubatanidza yepasi rose chichava chei? Zvakazoonekwa kuti iUSB4 2.0, iyo inopa80 Gbpsbandwidth yedata munzira imwe neimwe uye 60W power delivery (PD) yeconnector. Simba reUSB4 2.0 rinogona kusvika 240 W (48 V, 5 A). Kwagara kune shanduro dzakawanda dzeUSB, dzinogona kutsanangurwa sedzakasiyana-siyana. Zvisinei, nekubatana zvishoma nezvishoma kwema interfaces, huwandu hwemhando dzeUSB hwakaderera zvakanyanya. Pakazosvika USB4, USB-C interface ndiyo chete yasara. Sei kuchine 2.0 version? Shanduro huru yeUSB4 2.0 ndeyekutsigira kwayo data transfer rate inosvika 80 Gbps, ichipfuura zvachose Thunderbolt 4 interface. Ngationgororei zvakadzama.
Kare, USB4 1.0 standard yakagadzirwa zvichibva paThunderbolt 3 technology, ine huwandu hwakanyanya hwekutamisa data hwe40 Gbps. Shanduro ye2.0 yakagadzirwa zvichibva pakugadzirwa kwelayer itsva, ichiwedzera mwero wekutamiswa kwedata kubva pa40 Gbps kusvika ku80 Gbps, zvichiisa denga idzva rekushanda kweUSB-C ecosystem. Zvinofanira kucherechedzwa kuti mwero mutsva we80 Gbps unoda tambo dzinoshanda uye unogona kungotsigirwa nezvimwe zvigadzirwa zvepamusoro mune ramangwana.USB4 2.0dhizaini yedata yakagadziridzwawo. Nekuda kwehurongwa hutsva hwemuviri hwakavakirwa paPAM3 signal encoding mechanism uye 80 Gbps data cable itsva yakagadziriswa, zvishandiso zvinogona kushandisa bandwidth zvizere uye zvine mwero. Iyi update inowedzera kukanganisa.USB 3.2, Kutumira mavhidhiyo eDisplayPort, uye nzira dzedata dzePCI Express. Kare, mwero wepamusoro wekutumira USB 3.2 waive 20 Gbps (USB3.2 Gen2x2)Pasi pehurongwa hutsva hwedata, mwero weUSB 3.2 uchapfuura 20 Gbps uye uchasvika padanho repamusoro.
Panyaya yekuenderana, USB4 2.0 ichave ichishanda kumashure neUSB4 1.0, USB 3.2, uye Thunderbolt 3, saka hapana chikonzero chekunetseka nezvematambudziko ekuenderana. Pamusoro pezvo, kuti unakirwe nekufambiswa kwedata kwe80Gbps, chishandiso chitsva chinoshanda uye chinoshanda.USB-C kuenda kuUSB-CCable yedata inodiwa kuti isvike pakumhanya uku. Cable dzedata dzinoshanda uye dzinoshanda dzeUSB-C kuenda kuUSB-C dzichiri nebandwidth yepamusoro ye40Gbps. Kuti zvinyatsojeka macategories eUSB aripo, USB interface yakatanga kubatanidzwa nekuitumidza zita zvichibva pabandwidth yekutumira. Semuenzaniso, USB4 v2.0 inoenderana neUSB 80Gbps, USB4 inoenderana neUSB 40Gbps, USB 3.2 Gen2x2inoenderana ne20Gbps, USB 3.2 Gen2 inoenderana neUSB 10GbpsuyeUSB 3.2 Gen1inoenderana neUSB 5Gbps, nezvimwewo. Mapepa ekurongedza, mainterface labels, uye ma data cable labels zvinogona kuonekwa mumufananidzo unotevera.
Muna Gumiguru 2022, USB-IF yakanga yatoburitsa USB4 version 2.0 specification, iyo inogona kuita kuti transmission performance ye80 Gbps isvike.USB Type-CuyeKutumira Simba reUSB (USB PD)zvirevo zvakagadziridzwawo. Pasi pe USB4 version 2.0 specification, USB Type-C signal interface inogonawo kugadziriswa isina kuenzana, ichipa kumhanya kwepamusoro kunosvika 120 Gbps kune rumwe rutivi uku ichichengetedza kumhanya kwe 40 Gbps kune rumwe rutivi. Parizvino, ma monitors mazhinji e 4K emhando yepamusoro anosarudza kutsigira USB-C one-line connection yema laptops. Mushure mekutangwa kwe 80 Gbps USB4 2.0 solution, mamwe4K 144HzMa monitor kana 6K, 8K monitors anogona kubatana zviri nyore nema laptops kuburikidza ne USB-C. Iyo 80 Gbps USB interface inochengetedza USB Type-C port kuti ive nechokwadi chekuti inoenderana ne USB 4 Version 1.0 iripo, USB 3.2, USB 2.0 uye Thunderbolt 3. Pamusoro pezvo, "80 Gbps USB Type-C Data Cable" yakaburitswa pakupera kwegore rino inotsigira vhezheni yekumhanya kwe80 Gbps ukuwo ichitsigira simba rekuchaja re240W 48V/5A (USB PD EPR). Ma laptop matsva anotarisirwa kuvhurwa pakupera kwegore rino kana gore rinouya anotarisirwa kutanga kutsigira USB 80 Gbps. Kune rumwe rutivi, ma PC emitambo ane simba guru uye ma monitor achakwanisa kushandisa zviri nani mashandiro emakadhi emifananidzo; kune rumwe rutivi, external solid-state PCIe inogonawo kushanda zvakakwana.
