USB-KANA Iyo yazvino USB yekupa zita gungano inotaura kuti yekutanga USB3.0 uye USB3.1 haicha shandiswa, ese USB3.0 mwero anodaidzwa kunzi USB3.2, USB3.2 mwero ichaita yekare USB 3.0/3.1 interface zvese zvakabatanidzwa. kupinda mu USB3.2 standard, USB3.1 interface inonzi USB3.2 Gen 2, uye yekutanga USB3.0 interface inodaidzwa kunzi USB3.2 Gen 1, tichitarisa kuenderana, USB3.2 Gen 1 transmission speed is 5Gbps, USB3.2 Gen2 transmission speed is 10Gbps, USB3.2 Gen2x2 transmission speed is 20Gbps, saka USB3.1 Gen1 uye USB3.0 itsva tsanangudzo tsanangudzo inogona kunzwisiswa sechinhu chimwe, asi zita rakasiyana.Gen1 neGen2 zvinonzwisiswa kuti zvinoreva kuti nzira ye encoding yakasiyana, kushandiswa kwebandwidth kwakasiyana, uye Gen1 neGen1x2 intuitively yakasiyana nzira.Parizvino, zvinozivikanwa kuti mabhodhi akawanda epamusoro-soro ane USB3.2Gen2x2 interface, mamwe ari TYPE C interface, mamwe USB interface, uye ikozvino TYPE C interface inonyanya .Musiyano pakati peGen1 neGen2, Gen3
Kuenzanisa kwe USB3.2 uye yazvino USB4
1. Kuendesa bandwidth: USB 3.2 inosvika 20Gbps, nepo USB4 iri 40Gbps.
2. Transfer protocol: USB 3.2 inonyanya kutumira data kuburikidza ne USB protocol, kana kugadzirisa USB neDP kuburikidza neDP Alt Mode (imwe nzira).USB4 inovhara USB 3.2, DP uye PCIe mapuroteni mumapaketi kuburikidza netunnel tekinoroji uye inoatumira panguva imwe chete.
3. DP kutapurirana: inogona kutsigira DP 1.4.USB 3.2 inogadzirisa zvinobuda kuburikidza neDP Alt Mode;Pamusoro pekugadzirisa zvinobuda kuburikidza neDP Alt Mode (imwe nzira), USB4 inogona zvakare kubvisa DP data kuburikidza ne USB4 tunneling protocol mapaketi.
4, PCIe kutapurirana: USB 3.2 haitsigire PCIe, USB4 inotsigira.PCIe data inotorwa kuburikidza ne USB4 tunneling protocol mapaketi.
5, TBT3 kutapurirana: USB 3.2 haitsigirwe, USB4 inotsigirwa, kureva, kuburikidza ne USB4 tunnel protocol mapaketi kuburitsa PCIe uye DP data.
6, Host to Host: kutaurirana pakati pemugamuchiri neanotambira, USB3.2 haitsigire, USB4 rutsigiro.Kunyanya USB4 inotsigira PCIe protocol kutsigira basa iri.
Ongorora: Tunneling inogona kuoneka senzira yekubatanidza data kubva kune akasiyana maprotocol, uchishandisa misoro kusiyanisa marudzi.
Mu USB 3.2, kutapurirana kweDisplayPort vhidhiyo uye USB 3.2 data kunofambiswa pane akasiyana chiteshi adapta, nepo muUSB4, DisplayPort vhidhiyo, USB 3.2 data uye PCIe data inogona kufambiswa pachiteshi chimwe chete, ndiwo musiyano mukuru pakati pezviviri izvi.Iwe unogona kuona mufananidzo uri pasi apa kuti uwedzere kunzwisisa kwako.
USB4 chiteshi inogona kufungidzirwa senzira dzinogona kupfuura dzakasiyana mhando dzemotokari, uye USB data, DP data, uye PCIe data inogona kufungidzirwa semotokari dzakasiyana.Kune mota dzakasiyana mugwara rimwe chete kutyaira zvine kurongeka, uye USB4 inotumira mhando dzakasiyana dze data pachiteshi chimwe chete.USB3.2, DP uye PCIe data inotanga kuunganidzwa pamwe chete, inotumirwa kuburikidza nechiteshi chimwe chete, inotumirwa kumidziyo yemumwe nemumwe, yozopatsanurwa kuita matatu akasiyana e data.
USB3.2 cable chimiro tsananguro
Mune iyo USB 3.2 yakatarwa, iyo yepamusoro-yekumhanya hunhu hwe USB Type-C inoshandiswa zvizere.USB Type-C ine maviri akakwira-kumhanya dhata chiteshi, ane mazita (TX1+/TX1-, RX1+/RX1-) uye (TX2+/TX2-, RX2+/RX2-), yaimbova USB 3.1 yaingoshandisa imwe yematanho kufambisa data. , uye imwe chiteshi yaivepo nenzira yekuchengetedza.Mu USB 3.2, nzira mbiri dzinogona kugoneswa pazvinenge zvakakodzera, uye kukurumidza kwekufambisa kwe10Gbps pachiteshi kunogona kuwanikwa, kuitira kuti mari iite 20Gbps, uchishandisa 128b / 132b encoding, iyo chaiyo data data inogona kusvika kusvika 2500MB / s, iyo. yakapetwa kaviri iyo yanhasi USB 3.1.Zvakakodzera kutaura kuti chiteshi chinochinja che USB 3.2 haina musono zvachose uye haidi kushaikwa kwakakosha nemushandisi.
USB3.1 tambo dzinobatwa nenzira yakafanana ne USB 3.0.Impedance control: Iyo impedance yeSDP yakadzivirirwa yekusiyanisa mutsara inodzorwa pa90Ω ± 5Ω, uye iyo imwechete-inopera coaxial mutsara inodzorwa pa45Ω ± 3Ω.Iko kunonoka mukati meiyo mutsauko pairi isingasviki 15ps/m, uye kumwe kurasikirwa kwekuisa uye zvimwe zviratidzo zvinopindirana ne USB3.0, uye tambo dhizaini inosarudzwa zvinoenderana nemabasa uye mapoka emamiriro ekushandisa uye zvinodiwa: VBUS: 4 waya kuti ive nechokwadi chekuti voltage uye ikozvino;Vconn: kusiyana neVBUS, inongopa huwandu hwemagetsi e3.0 ~ 5.5V;Simba chete chip chetambo;D +/D-: USB 2.0 chiratidzo, kuitira kutsigira mberi uye reverse plugging, pane maviri maviri ezviratidzo padivi resokisi;TX +/- uye RX +/-: 2 seti yezviratidzo, 4 peya dzezviratidzo, tsigiro mberi uye reverse kududzira;CC: Gadzirisa masaini, simbisa uye maneja sosi-terminal kubatana;SUB: Yakawedzerwa basa siginecha, inowanikwa kune odhiyo.
Kana iyo impedance yeyakadzivirirwa mutsara wekusiyanisa inodzorwa pa90Ω ± 5Ω, iyo coaxial mutsara inoshandiswa, chiratidzo chepasi kudzoka chiri kuburikidza neyakavharidzirwa GND, uye iyo imwechete-inopera coaxial mutsara inodzorwa pa45Ω ± 3Ω, asi pasi pehurefu hwakasiyana hwetambo. , iyo mamiriro ekushandisa eiyo interface anosarudza kusarudzwa kwevanobatika uye kusarudzwa kwetambo chimiro.
USB 3.2 Gen 1x1 - SuperSpeed, 5 Gbit/s (0.625 GB/s) data kusaina mwero pamusoro penzira imwe uchishandisa 8b/10b encoding, yakafanana ne USB 3.1 Gen 1 uye USB 3.0.
USB 3.2 Gen 1x2 - SuperSpeed+, itsva 10 Gbit/s (1.25 GB/s) data reti pamusoro penzira mbiri uchishandisa 8b/10b encoding.
USB 3.2 Gen 2x1 - SuperSpeed+, 10 Gbit/s (1.25 GB/s) data rate pamusoro pemukoto mumwe uchishandisa 128b/132b encoding, yakafanana ne USB 3.1 Gen 2.
USB 3.2 Gen 2x2 - SuperSpeed+, itsva 20 Gbit/s (2.5 GB/s) data reti pamusoro penzira mbiri uchishandisa 128b/132b encoding.
