Nhanganyaya kuType-C Connectors
USB Type-CYave chinhu chikuru pamusika nekuda kwekubatsira kwayo pakubatanidza uye ikozvino yava pedyo nekusvika pamusoro. Kushandiswa kwayo muminda yakasiyana-siyana hakumisiki. MacBook yeApple yakaita kuti vanhu vazive nyore kwe USB Type-C interface uye yakaratidzawo mafambiro ekuvandudza michina yeramangwana. Mumazuva anotevera, michina yakawanda ye USB Type-C ichaburitswa. Pasina mubvunzo, USB Type-C interface ichapararira zvishoma nezvishoma uye ichatonga musika mumakore mashoma anotevera. Uyezve, pamidziyo yenharembozha yakaita semafoni nemapiritsi, ine zvinhu zvakawanda zvinoita kuti ikwanise kuchaja nekukurumidza, kukurumidza kutamisa data, uye kutsigira kubuda kwe display. Yakakodzera zvakanyanya se output interface yemidziyo yenharembozha. Chinonyanya kukosha, pane kudiwa kwakasimba kwe universal interface yekuvandudza kubatana pakati pemidziyo yakasiyana-siyana. Izvi zvinogona kuita kuti Type-C interface ive interface yakabatana yeramangwana, kwete chete muminda yeapplication yaunoona!
Kana yakagadzirwa zvichienderana nezvinodiwa neindasitiri yeUSB Association, USB Type-C connector inofanira kunge iri yefashoni, yakatetepa, uye diki, yakakodzera nharembozha. Panguva imwe chete, inofanirwa kusangana nezvinodiwa zvine simba rekubatana uye yakakodzera kushandiswa kwakasiyana-siyana kwemaindasitiri. USB Type-C connector inopa plug interface inodzoserwa; socket inogona kuiswa kubva chero divi, zvichiita kuti kubatana kuve nyore uye kwakavimbika. Iyi connector inofanirawo kutsigira maprotocol akasiyana-siyana uye inogona kushanda kumashure neHDMI, VGA, DisplayPort, nedzimwe mhando dzekubatanidza kubva kune imwe C-type USB port kuburikidza nemaadapter. Kuti kugadzirisa mashandiro mu electromagnetic interference (EMI) nedzimwe nzvimbo dzakaoma, kufungwa kwakawanda nezvekugadzira kunodiwa. Zvinokurudzirwa kuti vagadziri vasarudze vatengesi veconnector vane TID certification kudzivirira matambudziko mu terminal applications!
IyoUSB Type-C 3.1Iyo interface ine mabhenefiti matanhatu makuru:
1) Kushanda kwakazara: Inotsigira data, odhiyo, vhidhiyo, uye kuchaja panguva imwe chete, ichiisa hwaro hwedata rinomhanya zvakanyanya, odhiyo yedhijitari, vhidhiyo ine tsananguro yepamusoro, kuchaja nekukurumidza, uye kugovera zvishandiso zvakawanda. Waya imwe chete inogona kutsiva tambo dzakawanda dzaimboshandiswa kare.
2) Kupinza kunodzoserwa shure: Kufanana neApple Lightning interface, kumberi nekumashure kwechiteshi zvakafanana, zvichitsigira kupinza kunodzoserwa shure.
3) Kutumira kwenzira mbiri: Data nesimba zvinogona kutumirwa kumativi ese ari maviri.
4) Kuenderana neKudzokera Kumashure: Kuburikidza nemaadapter, inogona kuenderana neUSB Type-A, Micro-B, nedzimwe nzvimbo dzekubatanidza.
5) Saizi diki: Saizi yeinterface ndeye 8.3mm x 2.5mm, inenge chikamu chimwe muzvitatu chehukuru hweinterface yeUSB-A.
6) Kumhanya kwakanyanya: Kunoenderana neUSB 3.1protocol, inogona kutsigira kutumira data kusvika ku10Gb/s, sengeUSB C 10GbpsuyeUSB 3.1 Gen 2zvinodiwa, zvichiita kuti pave nekufambiswa kwemagetsi nekukurumidza zvikuru.
Mirayiridzo yekutaurirana ne USB PD
USB - Power Delivery (USB PD) imhando yeprotocol inogonesa kutumira panguva imwe chete kusvika ku100W yesimba uye kutaurirana kwedata pamusoro petambo imwe chete; USB Type-C imhando itsva zvachose yeUSB connector inogona kutsigira mitemo mitsva yakaita seUSB 3.1 (Gen1 naGen2), Display Port, uye USB PD; voltage yepamusoro inotsigirwa uye current yeUSB Type-C port i5V 3A; kana USB PD ikashandiswa muUSB Type-C port, inogona kutsigira simba re240W rakatsanangurwa muUSB PD specification, saka, kuva neUSB Type-C port hazvirevi kuti inotsigira USB PD; USB PD inoita kunge ingori protocol yekutumira simba nekutarisira, asi kutaura zvazviri, inogona kushandura mabasa eport, kutaurirana netambo dzinoshanda, kubvumira DFP kuti ive mudziyo wekupa simba uye mamwe mabasa mazhinji epamusoro. Saka, zvishandiso zvinotsigira PD zvinofanirwa kushandisa CC Logic chips (E-Mark chips), semuenzaniso, kushandisaWaya ye USB C ye5A 100Winogona kuwana magetsi anoshanda zvakanaka.
Kuonekwa uye Kushandiswa kweVBUS yeType-C yeUSB
USB Type-C yawedzera mabasa ekuona nekushandisa magetsi panguva ino. Mamodhi matatu matsva emagetsi atangwa: USB power mode (500mA/900mA), 1.5A, uye 3.0A. Mamodhi matatu aya anotumirwa uye anoonekwa kuburikidza nemapini eCC. Kune maDFP anoda kugona kuburitsa magetsi panguva ino, mavalues akasiyana eCC pull-up resistors Rp anodiwa kuti izvi zviitike. Kune maUFP, kukosha kwevoltage paCC pin kunofanirwa kuonekwa kuti kuwane kugona kwemagetsi panguva ino kweimwe DFP.
Kutarisira nekuona DFP-ku-UFP uye VBUS
DFP ichiteshi cheUSB Type-C chiri panhare kana hub, chakabatana nemudziyo. UFP ichiteshi cheUSB Type-C chiri panhare kana hub, chakabatana neDFP yenhare kana hub. DRP ichiteshi cheUSB Type-C chinogona kushanda seDFP kana UFP. DRP inochinja pakati peDFP neUFP maminitsi makumi mashanu ega ega mustandby mode. Paunenge uchichinja kuenda kuDFP, panofanira kunge paine resistor Rp inodhonza kusvika kuVBUS kana kubuda kwesimba paCC pin. Paunenge uchichinja kuenda kuUFP, panofanira kunge paine resistor Rd inodhonza pasi kuenda kuGND paCC pin. Ichi chiito chekuchinja chinofanira kuzadzikiswa neCC Logic chip.
VBUS inogona kuburitswa chete kana DFP yaona kuiswa kweUFP. Kana UFP yabviswa, VBUS inofanira kudzimwa. Basa iri rinofanira kupedzwa neCC Logic chip.
Cherechedza: DRP yataurwa pamusoro apa yakasiyana neUSB-PD DRP. USB-PD DRP inoreva mapombi emagetsi anoshanda sePower Source (provider) uye Sink (consumer), semuenzaniso, USB Type-C port iri palaptop inotsigira USB-PD DRP, iyo inogona kushanda sePower Source (pakubatanidza USB drive kana nharembozha) kana Sink (pakubatanidza monitor kana power adapter).
Pfungwa yeDRP, pfungwa yeDFP, pfungwa yeUFP
Kutumirwa kwedata kunonyanya kuve nemaseti maviri ezviratidzo zvakasiyana, TX/RX. CC1 neCC2 mapini maviri ekiyi ane mabasa akawanda:
Kuona kubatana, kusiyanisa mativi ekumberi neakumashure, kusiyanisa DFP neUFP, inova ndiyo gadziriro yemaster-slave yeVbus, kune mhando mbiri dzeUSB Type-C neUSB Power Delivery.
Kugadzirisa Vconn. Kana paine chip muwaya, imwe CC inotumira chiratidzo, uye imwe CC inova Vconn yemagetsi. Kugadzirisa mamwe mamodhi, akadai sekubatanidza zvishongedzo zveaudio, DP, PCIE, kune mitsara mina yemagetsi neground yeimwe neimwe, DRP (Dual Role Port): dual-role port, DRP inogona kushandiswa seDFP (Host), UFP (Device), kana kushandura pakati peDFP neUFP. Mudziyo weDRP wakajairika ikombiyuta (kombuta inogona kushanda seUSB host kana mudziyo uchachajwa (Apple's new MacBook Air)), nharembozha ine OTG function (nharembozha inogona kushanda semudziyo uchachajwa nekuverenga data, kana sehost kupa simba kana kuverenga data kubva kuUSB drive), power bank (kuburitsa nekuchaja zvinogona kuitwa kuburikidza neUSB Type-C imwe chete, kureva kuti, iyi port inogona kuburitsa nekuchaja).
Nzira yakajairika yekushandisa host-client (DFP-UFP) yeUSB Type-C
Pfungwa yeCCpin
CC (Configuration Channel): Configuration Channel, iyi ichiteshi chitsva chekiyi chakawedzerwa muUSB Type-C. Mabasa ayo anosanganisira kuona kubatana kweUSB, kuona nzira chaiyo yekuisa, kusimbisa nekutarisira kubatana pakati pemidziyo yeUSB neVBUS, nezvimwewo.
Pane resistor yepamusoro inodhonza-kumusoro Rp paCC pin yeDFP, uye resistor yakaderera inodhonza-pasi Rd paUFP. Kana isina kubatanidzwa, VBUS yeDFP haina chinobuda. Mushure mekubatanidza, CC pin yakabatana, uye CC pin yeDFP ichaona resistor inodhonza-pasi Rd yeUFP, zvichiratidza kuti kubatana kwaitwa. Zvadaro, DFP ichavhura Vbus power switch uye simba rekuburitsa kuUFP. Ndeipi CC pin (CC1, CC2) inoona resistor inodhonza-pasi inosarudza divi rekuisa interface, uye inochinjawo RX/TX. Resistance Rd = 5.1k, uye resistance Rp ivalue isina chokwadi. Zvichienderana nedhayagiramu yapfuura, zvinogona kuonekwa kuti kune nzira dzakawanda dzemagetsi dzeUSB Type-C. Ungadzisiyanisa sei? Zvichibva pakuvanzika kweRp. Voltage inoonekwa neCC pin yakasiyana kana kukosha kweRp kwakasiyana, uye wobva wadzora DFP end kuti uite kuti ndeipi power supply mode. Zvinofanira kucherechedzwa kuti mapini maviri eCC akadhirowewa pamufananidzo uri pamusoro apa chaizvoizvo mutsetse mumwe chete weCC uri muwaya usina chip.
