Nhanganyaya kune Type-C Connectors
USB Type-Cyabuda semutambi ane mukurumbira mumusika nekuda kweiyo yekubatanidza mabhenefiti uye ikozvino yave padanho rekusvika pamusoro. Kushandiswa kwayo munzvimbo dzakasiyana-siyana hakumisiki. Apple's MacBook yakaita kuti vanhu vaone kureruka kweiyo USB Type-C interface uye yakaratidzawo maitiro ekuvandudza ezvishandiso zveramangwana. Mumazuva anouya, yakawanda uye yakawanda USB Type-C michina ichatangwa. Pasina kupokana, iyo USB Type-C interface ichaita zvishoma nezvishoma kupararira uye kutonga musika mumakore mashoma anotevera. Zvakare, panharembozha dzakadai semafoni uye mahwendefa, ine akati wandei maficha anogonesa kukurumidza kuchaja, yakakwira data yekumhanyisa kumhanya, uye tsigiro yekuratidzira kubuda. Iyo inonyanya kukodzera senge inobuda interface yenharembozha. Kunyanya kukosha, pane kudiwa kwakasimba kweiyo yepasirese interface yekusimudzira kubatana pakati pezvishandiso zvakasiyana. Aya maficha anogona kuita kuti Type-C interface ive yakabatana yeramangwana, kwete mundima dzekushandisa dzaunoona!
Kana yakagadzirwa zvinoenderana neindasitiri zviyero zve USB Association, iyo USB Type-C yekubatanidza inosungirwa kuve yefashoni, yakatetepa, uye compact, inokodzera nharembozha. Panguva imwecheteyo, inoda kusangana nepamusoro-simba zvinodiwa zvemubatanidzwa uye yakakodzera kune akasiyana maindasitiri ekushandisa. Iyo USB Type-C yekubatanidza inopa inodzoreredzwa plug interface; iyo socket inogona kuiswa kubva kune chero nzira, kuwana nyore uye yakavimbika kubatana. Ichi chinongedzo chinodawo kutsigira akawanda akasiyana maprotocol uye anogona kudzokera kumashure anoenderana neHDMI, VGA, DisplayPort, uye mamwe marudzi ekubatanidza kubva kune imwechete C-mhando USB port kuburikidza nemaadapter. Kugadzirisa mashandiro mumagetsi emagetsi kupindira (EMI) nedzimwe nharaunda dzakaomarara, mamwe magadzirirwo ekufunga anodiwa. Zvinokurudzirwa kuti vagadziri vasarudze vatengesi vekubatanidza neTID certification kudzivirira matambudziko mumaterminal application!
TheUSB Type-C 3.1interface ine zvitanhatu zvakakosha zvakanaka:
1) Kushanda kwakazara: Inotsigira data, odhiyo, vhidhiyo, uye kuchaja panguva imwe chete, ichiisa hwaro hwepamusoro-kumhanya data, dhijitari odhiyo, yakakwirira-tsanangudzo vhidhiyo, kukurumidza kuchaja, uye akawanda-zvishandiso kugovera. Imwe tambo inogona kutsiva tambo dzakawanda dzakamboshandiswa kare.
2) Inodzoreredzwa kuisirwa: Zvakafanana neApple Mheni interface, kumberi uye kumashure kwechiteshi kwakafanana, kunotsigira kudzoreredzwa kuiswa.
3) Bidirectional kutapurirana: Dhata uye simba zvinogona kufambiswa mumativi ese.
4) Kumashure kuenderana: Kuburikidza nemaadapter, inogona kuenderana ne USB Type-A, Micro-B, uye mamwe mainterface.
5) Saizi diki: Saizi yekubatanidza i8.3mm x 2.5mm, ingangoita chikamu chimwe muzvitatu chehukuru hwe USB-A interface.
6) High kumhanya: Inoenderana neUSB 3.1protocol, inogona kutsigira kusvika ku10Gb/s kutumira data, sengeUSB C 10GbpsuyeUSB 3.1 Gen 2zviyero, kuwana ultra-fast transmission.
USB PD Kukurukurirana Mirayiridzo
USB - Power Delivery (USB PD) iprotocol yakatarwa inogonesa kufambisa panguva imwe chete kusvika ku100W yesimba uye data kutaurirana pamusoro petambo imwe chete; USB Type-C chimiro chitsva che USB chinongedzo chinogona kutsigira nhevedzano yemazinga matsva akadai se USB 3.1 (Gen1 neGen2), Display Port, uye USB PD; iyo yakasarudzika yakanyanya kutsigirwa voltage uye ikozvino kune USB Type-C chiteshi ndeye 5V 3A; kana USB PD inoshandiswa mu USB Type-C port, inogona kutsigira 240W simba rinotsanangurwa mu USB PD tsanangudzo, saka, kuva ne USB Type-C port hazvirevi kuti inotsigira USB PD; USB PD inoita kunge ingori protocol yekufambiswa kwemagetsi uye manejimendi, asi kutaura zvazviri, inogona kushandura chiteshi chengarava, kutaurirana netambo dzinoshanda, inobvumira DFP kuti ive mudziyo wemagetsi uye mamwe akawanda mabasa epamberi. Naizvozvo, zvishandiso zvinotsigira PD zvinofanirwa kushandisa CC Logic chips (E-Mark chips), semuenzaniso, kushandisa a5A 100W USB C Cableinogona kuwana simba rinoshanda.
USB Type-C VBUS Yazvino Kuonekwa uye Kushandisa
Iyo USB Type-C yakawedzera ikozvino kuona uye kushandiswa kwemabasa. Matatu matsva ezvino modhi akaunzwa: iyo default USB simba modhi (500mA/900mA), 1.5A, uye 3.0A. Aya matatu mamodhi azvino anofambiswa uye anoonekwa kuburikidza neCC pini. Kune maDFP anoda kutepfenyura azvino kubuda kugona, hunhu hwakasiyana hweCC kudhonza-up resistors Rp hunodiwa kuita izvi. Kune maUFPs, kukosha kwevoltage paCC pini inoda kuwonekwa kuti iwane ikozvino kubuda kugona kweimwe DFP.
DFP-ku-UFP uye VBUS Management uye Kuona
DFP i USB Type-C chiteshi chiri pane iyo host kana hub, yakabatana kune mudziyo. UFP i USB Type-C chiteshi chiri pane mudziyo kana hub, yakabatana neanotambira kana hub's DFP. DRP i USB Type-C chiteshi chinogona kushanda seDFP kana UFP. DRP inochinja pakati peDFP neUFP yega yega 50ms mune yekumira mode. Kana uchichinjira kuDFP, panofanira kunge paine resistor Rp inokwevera kumusoro kuVBUS kana yazvino sosi inobuda paCC pini. Kana uchichinjira kuUFP, panofanira kunge paine resistor Rd inodhonzera pasi kuGND paCC pini. Ichi chiito chekuchinja chinofanira kupedzwa neCC Logic chip.
VBUS inogona chete kubuda kana DFP yaona kuiswa kweUFP. Kana UFP yabviswa, VBUS inofanira kudzimwa. Kuvhiya uku kunofanirwa kupedzwa neCC Logic chip.
Cherechedza: DRP yataurwa pamusoro yakasiyana ne USB-PD DRP. USB-PD DRP inoreva madoko emagetsi anoita seSimba Sosi (mupi) uye Sink (mutengi), semuenzaniso, USB Type-C chiteshi palaptop inotsigira USB-PD DRP, inogona kuita seSimba reSimba (kana uchibatanidza USB drive kana nhare mbozha) kana Sink (kana uchibatanidza chekutarisa kana magetsi adapta).
DRP pfungwa, DFP pfungwa, UFP pfungwa
Kufambiswa kwedata kunonyanya kuve nemaseti maviri ezviratidzo zvakasiyana, TX/RX. CC1 uye CC2 mapini maviri akakosha ane mabasa mazhinji:
Kuona kubatanidza, kusiyanisa pakati pemberi neshure mativi, kusiyanisa pakati peDFP neUFP, inova tenzi-muranda kumisikidzwa yeVbus, kune maviri marudzi e USB Type-C uye USB Power Delivery.
Kugadzirisa Vconn. Kana paine chip mutambo, imwe CC inotumira chiratidzo, uye imwe CC inova iyo magetsi ekupa Vconn. Kugadzirisa mamwe mamodhi, senge kana uchibatanidza odhiyo accessories, DP, PCIE, kune mana masimba uye mitsara yepasi kune imwe neimwe, DRP (Dual Role Port): mbiri-basa chiteshi, DRP inogona kushandiswa seDFP (Host), UFP (Chishandiso), kana dynamically chinja pakati peDFP neUFP. Chishandiso chakajairika cheDRP komputa (kombuta inogona kuita se USB host kana mudziyo unofanirwa kuchajwa (Apple's MacBook Air itsva)), nhare mbozha ine OTG inoshanda (nhare mbozha inogona kuita semudziyo uchachajwa uye kuverenga data, kana semugadziri kupa simba kana kuverenga data kubva ku USB drive), bhangi remagetsi (kuburitsa nekuchaja kunogona kuitwa kuburikidza neiyo imwe USB Type-C yekuchaja, iyo yekuchaja iyi USB Type-C).
Iyo yakajairwa host-mutengi (DFP-UFP) nzira yekushandisa ye USB Type-C
CCpin pfungwa
CC (Configuration Channel): Configuration Channel, iyi ichangobva kuwedzerwa kiyi chiteshi mu USB Type-C. Mabasa ayo anosanganisira kuona kubatana kwe USB, kuona kwakaringana nzira yekuisa, kumisikidza uye kugadzirisa hukama pakati pemidziyo ye USB neVBUS, nezvimwe.
Kune yekumusoro yekudhonza-kumusoro resistor Rp paCC pini yeDFP, uye yakaderera yekudhonza-pasi resistor Rd paUFP. Kana isina kubatana, iyo VBUS yeDFP haina chinobuda. Mushure mekubatanidza, pini yeCC yakabatana, uye CC pini yeDFP ichaona kudhonza-pasi resistor Rd yeUFP, zvichiratidza kuti kubatana kunoitwa. Zvadaro, DFP ichavhura Vbus simba rekushandura uye kubuda simba kuUFP. Ndeipi CC pini (CC1, CC2) inoona yekudonhedza-pasi resistor inosarudza yekuisa kutungamira kweiyo interface, uye zvakare inochinja RX/TX. Kupokana Rd = 5.1k, uye kuramba Rp kukosha kusingazivikanwe. Zvinoenderana neiyo dhizaini yapfuura, zvinogona kuoneka kuti kune akati wandei magetsi emagetsi e USB Type-C. Nzira yekuvasiyanisa sei? Inobva pakukosha kweRp. Iyo voltage yakaonekwa neCC pini yakasiyana kana kukosha kweRp kwakasiyana, uye wobva wadzora iyo DFP kupera kuti uite iyo magetsi emagetsi maitiro. Izvo zvinofanirwa kucherechedzwa kuti mapini maviri eCC akadhonzwa mumufananidzo uri pamusoro angori mutsetse mumwechete weCC mutambo isina chip.
