He Kupu Whakataki ki ngā Hononga Momo-C
Momo-C USBKua puta ake hei kaitākaro matua i te mākete nā ōna painga hononga, ā, kei te tata tonu ia ki te eke ki te tihi. Kāore e taea te aukati i tana whakamahinga i roto i ngā momo mara. Nā te MacBook a Apple i mōhio ai te tangata ki te whai huatanga o te atanga USB Momo-C, ā, i whakakitea hoki te ia whanaketanga o ngā taputapu o muri mai. I ngā rā e haere ake nei, ka nui haere ngā taputapu USB Momo-C ka whakarewaina. Kāore e kore, ka horapa haere te atanga USB Momo-C, ā, ka noho hei rangatira i te mākete i roto i ngā tau torutoru e whai ake nei. Heoi anō, i runga i ngā taputapu pūkoro pēnei i ngā waea me ngā papa, he maha ngā āhuatanga e āhei ai te utu tere ake, te tere whakawhiti raraunga teitei ake, me te tautoko i te putanga whakaaturanga. He pai ake hei atanga putanga mō ngā taputapu pūkoro. Ko te mea nui, he nui te hiahia mō tētahi atanga whānui hei whakarei ake i te hononga i waenga i ngā momo taputapu. Mā ēnei āhuatanga ka tino noho te atanga Momo-C hei atanga kotahi o te heke mai, ehara i te mea ko ngā mara tono anake e kitea ana e koe!
Ki te hangaia kia rite ki ngā paerewa ahumahi o te USB Association, ka tino huatau, ka angiangi, ka kiato hoki te hononga USB Momo-C, ā, he pai mō ngā taputapu pūkoro. I taua wā anō, me tutuki i a ia ngā whakaritenga kaha-teitei o te hononga, ā, me pai hoki mō ngā tono ahumahi maha. Ka whakaratohia e te hononga USB Momo-C he atanga mono hurihuri; ka taea te whakauru i te putanga mai i tētahi taha, ka taea ai te hononga ngāwari me te pono. Me tautoko hoki tēnei hononga i ngā kawa rerekē maha, ā, ka taea te hototahi whakamuri ki te HDMI, VGA, DisplayPort, me ētahi atu momo hononga mai i te tauranga USB momo-C kotahi mā roto i ngā urutau. Hei aro ki te mahi i roto i te pokanoa hikohiko (EMI) me ētahi atu taiao uaua, me whai whakaaro nui ki te hoahoa. E taunakihia ana kia whiriwhiria e ngā kaihanga ngā kaiwhakarato hononga me te tiwhikete TID hei karo i ngā raruraru i roto i ngā tono taunga!
TeUSB Momo-C 3.1E ono ngā painga nui o te atanga:
1) Ngā mahi katoa: Ka tautoko i ngā raraunga, ngā oro, ngā ataata, me te utu i te wā kotahi, ka whakatakoto i te turanga mō ngā raraunga tere-teitei, ngā oro matihiko, ngā ataata whakamārama-teitei, te utu tere, me te tiritiri maha-pūrere. Ka taea e te taura kotahi te whakakapi i ngā taura maha i whakamahia i mua.
2) Whakaurunga whakahurihuri: He rite ki te atanga Apple Lightning, he rite tonu te taha mua me te taha muri o te tauranga, e tautoko ana i te whakaurunga whakahurihuri.
3) Tukunga ā-rua: Ka taea te tuku raraunga me te hiko i ngā taha e rua.
4) Hototahi whakamuri: Mā ngā urutau, ka taea te hototahi ki te Momo USB-A, Micro-B, me ētahi atu atanga.
5) Rahi iti: Ko te rahi o te atanga he 8.3mm x 2.5mm, tata ki te hautoru o te rahi o te atanga USB-A.
6) Tere tere: Hototahi ki teUSB 3.1kawa, ka taea e ia te tautoko i te tuku raraunga tae atu ki te 10Gb/s, pērā iUSB C 10GbpsmeUSB 3.1 Whakatipuranga 2ngā paerewa, e tutuki ai te tuku tere rawa atu.
Ngā Tohutohu Whakawhitiwhiti Kōrero USB PD
Ko te USB - Power Delivery (USB PD) he whakaritenga kawa e āhei ai te tuku i te hiko tae atu ki te 100W me te whakawhitiwhiti raraunga i runga i te taura kotahi; Ko te USB Type-C he whakaritenga hou rawa atu mō te hononga USB ka taea te tautoko i te raupapa o ngā paerewa hou pēnei i te USB 3.1 (Gen1 me Gen2), te Tauranga Whakaatu, me te USB PD; ko te ngaohiko me te iahiko taunoa mōrahi e tautokona ana mō te tauranga USB Type-C ko te 5V 3A; ki te whakauruhia te USB PD ki roto i te tauranga USB Type-C, ka taea e ia te tautoko i te mana 240W kua tautuhia i roto i te whakaritenga USB PD, nō reira, ko te whai tauranga USB Type-C ehara i te mea e tautoko ana i te USB PD; te āhua nei ko te USB PD he kawa noa iho mō te tuku me te whakahaere hiko, engari ko te mea pono, ka taea e ia te whakarerekē i ngā tūranga tauranga, te whakawhitiwhiti kōrero me ngā taura hohe, te tuku i te DFP kia noho hei taputapu tuku hiko me te maha atu o ngā mahi matatau. Nō reira, me whakamahi ngā taputapu e tautoko ana i te PD i ngā maramara CC Logic (ngā maramara E-Mark), hei tauira, mā te whakamahi i teTaura USB C 5A 100Wka taea te whakatutuki i te tuku hiko whai hua.
Te Kimi me te Whakamahinga o te Iahiko VBUS Momo-C USB
Kua tāpirihia e te Momo-C USB ngā mahi kimi me te whakamahi i te au. E toru ngā momo au hou kua whakaurua: te aratau mana USB taunoa (500mA/900mA), 1.5A, me te 3.0A. Ka tukuna, ka kitea hoki ēnei momo au e toru mā roto i ngā pine CC. Mō ngā DFP e hiahia ana ki te kaha whakaputa au pāho, me whai uara rerekē o ngā ātete kukume CC Rp hei whakatutuki i tēnei. Mō ngā UFP, me kitea te uara ngaohiko i runga i te pine CC hei whiwhi i te kaha whakaputa au o tētahi atu DFP.
Te Whakahaere me te Kimi i te DFP-ki-UFP me te VBUS
Ko te DFP he tauranga Momo-C USB kei runga i te kaihautū, i te pokapū rānei, e hono ana ki te pūrere. Ko te UFP he tauranga Momo-C USB kei runga i te pūrere, i te pokapū rānei, e hono ana ki te DFP o te kaihautū, o te pokapū rānei. Ko te DRP he tauranga Momo-C USB ka taea te mahi hei DFP, hei UFP rānei. Ka huri te DRP i waenga i te DFP me te UFP i ia 50ms i te aratau tūtatari. Ina huri ki te DFP, me whai ātete Rp e kukume ana ki runga ki te VBUS, me whai pūtake putanga au rānei i runga i te pine CC. Ina huri ki te UFP, me whai ātete Rd e kukume ana ki raro ki te GND i runga i te pine CC. Me whakaoti tēnei mahi whakawhiti e te maramara CC Logic.
Ka taea anake te whakaputa i te VBUS ina kitea e te DFP te whakaurunga o te UFP. Kia tangohia te UFP, me whakaweto te VBUS. Me whakaoti tēnei mahi e te maramara CC Logic.
Kia mōhio: He rerekē te DRP kua whakahuatia ake nei i te USB-PD DRP. Ko te USB-PD DRP e pā ana ki ngā tauranga hiko e mahi ana hei Pūtake Hiko (kaiwhakarato) me te Totohu (kaihoko), hei tauira, ka tautoko te tauranga Momo-C USB i runga i te pona i te USB-PD DRP, ka taea te mahi hei Pūtake Hiko (ina hono ana i te puku USB, i te waea pūkoro rānei) i te Totohu rānei (ina hono ana i te aroturuki, i te urutau hiko rānei).
Ariā DRP, ariā DFP, ariā UFP
Ko te tuku raraunga he mea hanga i ngā huinga tohu rerekētanga e rua, ko TX/RX. Ko CC1 me CC2 he pine matua e rua, he maha ā rāua mahi:
Te kimi hononga, te wehewehe i waenga i ngā taha o mua me muri, te wehewehe i waenga i te DFP me te UFP, koinei te whirihoranga matua-pononga mō Vbus, e rua ngā momo USB Momo-C me te USB Power Delivery.
Te Whirihora i a Vconn. Ina he maramara kei roto i te taura, ka tukuna he tohu e tetahi CC, ā, ko tetahi CC ka noho hei pūtake hiko Vconn. Mēnā ka whirihorahia ētahi atu momo, pērā i te hono i ngā taputapu oro, DP, PCIE, e whā ngā raina hiko me te whenua mō ia momo, DRP (Tauranga Tūranga Rua): tauranga tūranga-rua, ka taea te whakamahi i te DRP hei DFP (Kaihautū), UFP (Pūrere), ka taea rānei te whakawhiti hihiri i waenga i te DFP me te UFP. Ko tētahi taputapu DRP noa he rorohiko (ka taea e te rorohiko te mahi hei kaihautū USB, hei taputapu rānei hei utu (MacBook Air hou a Apple)), he waea pūkoro me te mahi OTG (ka taea e te waea pūkoro te mahi hei taputapu hei utu me te pānui raraunga, hei kaihautū rānei hei whakarato hiko, hei pānui raraunga rānei mai i te puku USB), he pēke hiko (ka taea te tuku me te utu mā te Momo-C USB kotahi, arā, ka taea e tēnei tauranga te tuku me te utu).
Ko te tikanga whakatinanatanga tūmau-kiritaki (DFP-UFP) o te USB Momo-C
Ariā CCpin
CC (Hongere Whirihoranga): Hongere Whirihoranga, he hongere matua hou tēnei i roto i te USB Momo-C. Kei roto i āna mahi ko te kimi hononga USB, te kimi i te ahunga whakauru tika, te whakatū me te whakahaere i te hononga i waenga i ngā taputapu USB me te VBUS, me ētahi atu.
Kei te pine CC o DFP he ātete kukume-ake Rp o runga, me te ātete kukume-iho Rd o raro i te UFP. Ina kore e honoa, kāore he putanga o te VBUS o DFP. Whai muri i te hononga, ka honoa te pine CC, ā, ka kitea e te pine CC o DFP te ātete kukume-iho Rd o UFP, e tohu ana kua oti te hononga. Kātahi ka whakatuwherahia e te DFP te pana mana Vbus ka tukuna te mana ki te UFP. Ko tēhea pine CC (CC1, CC2) e kite ana i te ātete kukume-iho e whakatau ana i te ahunga whakaurunga o te atanga, ā, ko ngā pana RX/TX anō hoki. Ko te ātete Rd = 5.1k, ā, he uara kāore i te tino mārama te ātete Rp. E ai ki te hoahoa o mua, ka kitea he maha ngā momo tuku hiko mō te USB Momo-C. Me pēhea te wehewehe i a rātou? Kei runga i te uara o Rp. He rerekē te ngaohiko i kitea e te pine CC ina he rerekē te uara o Rp, kātahi ka whakahaere i te pito DFP ki te whakahaere i tēhea aratau tuku hiko. Me mōhio ko ngā pine CC e rua i tuhia i te pikitia i runga ake nei he rārangi CC kotahi noa iho i roto i te taura me te kore he maramara.
