USB 3.2 Yakakurumbira Sainzi (Chikamu 2)

Mune iyo USB 3.2 yakatarwa, iyo yepamusoro-yekumhanya ye USB Type-C inoshandiswa zvizere. USB Type-C ine maviri akakwira-kumhanya dhata nzira, ane mazita (TX1+/TX1-, RX1+/RX1-) uye (TX2+/TX2-, RX2+/RX2-). Pakutanga, USB 3.1 yaingoshandisa imwe yenzira kufambisa data, neimwe chiteshi chiripo se backup. Mu USB 3.2, machanera ese ari maviri anogona kugoneswa pasi pemamiriro akakodzera uye kuwana yakanyanya kumhanya yekutapurirana ye10 Gbps pachiteshi chega chega, zvichikonzera huwandu hwemakumi maviri Gbps. Iine 128b/132b encoding, iyo chaiyo data yekumhanyisa inogona kusvika ingangoita 2500 MB/s, inova yakananga kaviri kana ichienzaniswa neyazvino USB 3.1. Izvo zvakakosha kucherechedza kuti chiteshi chinochinja mu USB 3.2 haina musono uye haidi chero yakakosha mashandiro kubva kumushandisi.

Chiratidzo uye nzira yekudzivirira yekugadzirisa ye USB3.1 tambo inopindirana neye USB3.0. Iyo impedance control yeSDP yakadzivirirwa mutsara wemutsara inodzorwa pa90Ω ± 5Ω, uye iyo imwechete-inopera coaxial mutsara inodzorwa pa45Ω ± 3Ω. Iko kunonoka kwemukati kwepairi yekusiyanisa iri pasi pe15ps / m, uye imwe yekuisa kurasikirwa uye zvimwe zviratidzo zvinoenderana ne USB3.0. Chimiro chetambo chinosarudzwa maererano nemamiriro ekushandiswa uye basa uye chikamu chinodiwa: VBUS: 4 waya kuti ive nechokwadi chekuyerera kwemagetsi uye ikozvino; Vconn: Yakasiyana neVBUS, inongopa huwandu hwemagetsi e3.0 ~ 5.5V; chete inopa simba kune chip yetambo; D +/D-: USB 2.0 chiratidzo; kutsigira kumberi nekudzosera kupinza, pane maviri maviri ezviratidzo padivi resokisi; TX +/- uye RX +/-: 2 mapoka ezviratidzo, 4 mapeji ezviratidzo, anotsigira mberi uye reverse kuiswa; CC: siginecha yekumisikidza, kusimbisa uye kugadzirisa kubatana pakati penzvimbo uye terminal; SUB: chiratidzo chekuwedzera chebasa, chinogona kushandiswa kune odhiyo.

Kana iyo impedance yeyakadzivirirwa mutsara wemutsara ichidzorwa pa90Ω ± 5Ω, uye coaxial mutsara unoshandiswa, chiratidzo chepasi chekudzoka chiri kuburikidza neyakavharidzirwa GND. Kune imwe-inopera coaxial mitsara, iyo impedance inodzorwa pa45Ω ± 3Ω. Nekudaro, iyo sarudzo yekubatanidza mapoinzi uye tambo chimiro zvinoenderana nemamiriro ekushandisa uye kureba kwetambo dzakasiyana.
