Ndimaona kuti DisplayPort Alternate Mode ndi imodzi mwazinthu zabwino kwambiri za USB-C, ndipo ngakhale ma laputopu ndi mafoni otsika mtengo kwambiri (kapena atsoka) sazithandizira, ndikwabwino kukhala ndi chipangizo chomwe chimathandizira. Zachidziwikire, nthawi zina kampani yayikulu imapeza chisangalalo chimenecho mwachindunji, monga momwe Google idachitira.
Makamaka, kudzera pa USB-C mutha kupeza Thunderbolt 3, ndipo posachedwa Bingu 4, koma mpaka pano ndizabwino kwambiri. Thunderbolt 3 poyambirira inali yodziwika bwino yomwe pamapeto pake idatsegulidwa ndi Intel. Zikuoneka kuti sali otseguka mokwanira kapena ali ndi chenjezo lina, ndipo popeza zida za Thunderbolt 3 zakuthengo zikumangidwabe ndi tchipisi ta Intel, ndikuganiza kuti kusowa kwa mpikisano ndichifukwa chake mitengo imakhalabe yokhazikika. gawo la digito. Chifukwa chiyani mukuyang'ana zida za Thunderbolt poyambira? Kuphatikiza pa liwiro lapamwamba, palinso chinthu china chakupha.
Mumapeza bandwidth ya PCIe pa Thunderbolt komanso mpaka 4x bandwidth! Uwu wakhala mutu wovuta kwambiri kwa iwo omwe amafunikira thandizo la eGPU kapena kusungirako mwachangu kunja ngati ma drive a NVMe omwe obera ena amagwiritsa ntchito ma FPGA ophatikizidwa ndi PCIe. Ngati muli ndi makompyuta awiri opangidwa ndi Thunderbolt (mwachitsanzo, ma laputopu awiri), mukhoza kuwagwirizanitsa pogwiritsa ntchito chingwe cha Thunderbolt - izi zimapanga mawonekedwe othamanga kwambiri pakati pawo popanda zigawo zina. Inde, inde, Bingu limatha kuwongolera mosavuta DisplayPort ndi USB3 mkati. Tekinoloje ya Thunderbolt ndiyamphamvu kwambiri komanso yokoma kwa ogwiritsa ntchito apamwamba.
Komabe, kuziziritsa konseku kumatheka kudzera m'magulu aukadaulo komanso ovuta. Bingu si chinthu chomwe wobera yekha amatha kupanga mosavuta, ngakhale wina ayesetse tsiku lina. Ndipo ngakhale doko la Thunderbolt lili ndi zinthu zambiri, mbali ya pulogalamuyo nthawi zambiri imayambitsa mavuto, makamaka zikafika pazinthu monga kuyesa kugona kuti mugwire ntchito pa laputopu osaphwanya pachimake cha eGPU. Ngati sizikuwonekerabe, ndikuyembekezera kuti Intel ayike pamodzi.
Ndimati "multiplexer". Ichi ndi chiyani? Mwachidule, gawo ili limathandizira kugwirana chanza kothamanga kwambiri malinga ndi kasinthasintha wa USB-C.
High-Speed Lane ndi gawo la USB-C lomwe limakhudzidwa kwambiri ndi kuzungulira kwa madoko. Ngati doko lanu la USB-C likugwiritsa ntchito High Speed Lane, mudzafunika chip multiplexer (multiplexer) kuti muthe kuyendetsa matembenuzidwe awiri a USB-C - kugwirizanitsa momwe madoko ndi zingwe zimayendera mbali zonse ziwiri ndi olandila othamanga kwambiri mkati. . ndipo ma transmitters amafananizidwa ndi chipangizo cholumikizidwa. Nthawi zina, ngati chipangizo chothamanga kwambiri chapangidwira USB-C, zochulukitsa izi zimakhala mkati mwa chip chothamanga kwambiri, koma nthawi zambiri zimakhala tchipisi tosiyana. Mukufuna kuwonjezera thandizo la Hi-Speed USB-C ku chipangizo chomwe sichigwirizana ndi Hi-Speed USB-C? Multiplexers adzathandizira ntchito zoyankhulirana zothamanga kwambiri.
Ngati chipangizo chanu chili ndi cholumikizira cha USB-C chokhala ndi High Speed Lane, mudzafunika multiplexer - zingwe zokhazikika ndi zida zolumikizira sizikufunika. Nthawi zambiri, ngati mukugwiritsa ntchito chingwe kulumikiza zida ziwiri zothamanga kwambiri zokhala ndi mipata ya USB-C, onse amafunikira chochulukira - kuwongolera chingwe ndiudindo wa chipangizo chilichonse. Kumbali zonse ziwiri, multiplexer (kapena wolamulira wa PD wolumikizidwa ndi multiplexer) adzayang'anira njira ya pini ya CC ndikuchita molingana. Komanso, ambiri mwa ma multiplexers amagwiritsidwa ntchito pazifukwa zosiyanasiyana, kutengera zomwe mukufuna kuchokera padoko.
Mudzawona ma multiplexer a USB3 m'ma laputopu otsika mtengo omwe amangogwiritsa ntchito USB 3.0 pa doko la Type-C, ndipo ngati imathandizira DisplayPort, mudzakhala ndi chowonjezera chokhala ndi chowonjezera chophatikiza ma siginecha awa. Mu Thunderbolt, multiplexer idzamangidwa mu Thunderbolt chip. Kwa obera omwe amagwira ntchito ndi USB-C koma alibe mwayi wopita ku Bingu kapena safuna Bingu, TI ndi VLI amapereka angapo ochulukitsa abwino pazifukwa zosiyanasiyana. Mwachitsanzo, ndakhala ndikugwiritsa ntchito DisplayPort pa USB-C posachedwa, ndipo VL170 (ikuwoneka ngati 1: 1 chojambula cha TI's HD3SS460) imawoneka ngati chip chachikulu cha DisplayPort + USB3 combo ntchito.
Zochulukira za USB-C zomwe zimathandizira DisplayPort (monga HD3SS460) sizimawongolera mapini a CC ndikusintha kuzindikira, koma ndiye malire oyenera - DisplayPort imafuna ulalo wa PD wokhazikika, womwe ndi wofunikira kwambiri. multiplexer mphamvu.
