Yintoni i-100BASE-T1

I-100BASE-T1 ludibaniso olusekelwe kubuchwephesha be-Ethernet obukhoyo.

1) IEEE 100BASE-TX

- Duplex simplex unxibelelwano

- MLT-3 (ukudluliselwa kwamanqanaba amaninzi) -> 125Msps (iisampulu zesigidi/yesibini) 65~80MHz bandwidth)

Izibini ezimbini ezijijekileyo – akukho mpazamo yokulungiswa kwekhowudi

- Akukho teknoloji yokukhansela i-echo kunye ne-crosstalk kwi-DSP

Ulungelelwaniso lweNgxelo yeSigqibo (DFE)

2) IEEE 1000BASE-T - unxibelelwano olupheleleyo lwe-duplex

- 4D-PAM5 -> 125Msps (iisampulu zesigidi ngomzuzwana) 65~80MHz bandwidth) - izibini ezine ezijijekileyo

- Isihluzo sothumelo lwempendulo engaphelelanga

- Amanqanaba awongezelelweyo okulungisa iimpazamo kwiikhowudi

- I-DSP ine-echo kunye ne-crosstalk yokukhansela iteknoloji

Ulungelelwaniso lweNgxelo yeSigqibo (DFE)

3) IEEE 100BASE-T1 - unxibelelwano olupheleleyo lwe-duplex - PAM3 - 66.7Msps (iisampulu zezigidi ngesekhondi) 27MHz bandwidth - isibini esijijekileyo

—— Itekhnoloji yokurhoxiswa kwe-Echo —— Ukulingana kweNgxelo yeSigqibo (DFE)

3. Ethernet VS ibhasi yemveli

3.1 Unxibelelwano olusekelwe kwinethiwekhi

1) Zonke iindawo ezikwibhasi yesiqhelo ziqhagamshelwe kwindawo enye yothumelo;umzekelo, ii-terminal nodes (ECUs) zinokudityaniswa kwibhasi enye ye-CAN, kwaye iimpawu zombane kwibhasi ye-CAN zinokuchaphazela zonke iitheminali ezincanyathiselwe ebhasini.

Ngokubanzi, sibiza i-CAN njenge-CAN Bus okanye i-CAN Network.

I-2) I-Ethernet yindlela yokunxibelelana yothungelwano olutshintshileyo, apho zonke ii-terminal nodes kufuneka zidibaniswe ngokutshintsha kwaye zonke iinkcukacha ezidlulisiweyo kufuneka zithunyelwe ngokutshintsha. ungabhekiseli kwibhasi ye-Ethernet, kodwa kwinethiwekhi ye-Ethernet.

4. Ukusetyenziswa kwe-Ethernet ekwibhodi

4.1 Imbonakalo yomfanekiso we-eriyali – uqhagamshelo olukwisantya esiphezulu

1) I-Broadcom BroadR-Reach, i-100 Mbit / s, i-duplex epheleleyo, isibini esijijekileyo - ithatha indawo yocingo olunqabileyo olukhuselekileyo

- Unxibelelwano lweendlela ezimbini

2) Sebenzisa i-bandwidth ephezulu

3) Ukusasazwa kwevidiyo esekwe kwi-MAC kunye neemfuno ezingqongqo zexesha

I-4) Imisebenzi ye-ADAS ephuculweyo (iikhamera ezongezelelweyo, i-millimeter-wave radar, i-laser radar, njl.) - isisombululo esiphezulu kunye nesantya sefreyimu, ukunyanzeliswa okuncinci

- Funa izinga losulelo lwe-1000Mbit/s nangaphezulu

4.2 I-Ethernet njengothungelwano lomqolo wesithuthi esingaphakathi

Ibhasi yemoto yexesha elizayo iya kuthatha indawo yebhasi ye-CAN kunye ne-Ethernet njengenethiwekhi ye-backbone, kwaye i-subnets iya kuqulunqwa ngabalawuli abaninzi be-domain.I-domain nganye esebenzayo inikwe umlawuli wesizinda, kunye nokudityaniswa kweenkqubo ngaphakathi kwesizinda ngasinye kusenokusebenzisa i-CAN kwaye Iibhasi zonxibelelwano ze-FlexRay.Abalawuli be-domain abahlukeneyo badibaniswe ngokusebenzisa i-Ethernet ephezulu yokusebenza njengenethiwekhi ye-backbone, kwaye utshintshiselwano lwedatha lufezekiswa ngamasango e-Ethernet, ngaloo ndlela yenze ngokubambisana i-architecture ye-E / E esekelwe kubalawuli besizinda.

4.3 Kwibhodi ye-Ethernet yokuhanjiswa kwamandla

Amandla phezu kwe-Ethernet (POE) iteknoloji enokudlulisa idatha kwiintambo eziphothiweyo ngelixa ngaxeshanye inika amandla izixhobo zokugqibela ezixhunyiwe, ukuphelisa imfuno yeentambo zamandla zangaphandle kwii-terminals kunye nokunciphisa ubunzima bokunikezelwa kwamandla.

Iimpawu eziphambili zobonelelo lwamandla enkqubo yonikezelo lwamandla esemgangathweni yePOE zezi:

1) I-voltage iphakathi kwe-44-57V, enexabiso eliqhelekileyo le-48V.

I-2) Ubuninzi obuvumelekileyo okwangoku yi-550mA, kwaye ubuninzi bokuqalisa ngoku bu-500mA.

3) Ukusebenza okuqhelekileyo okwangoku yi-10-350mA, kwaye ukufumanisa ukugqithiswa kwangoku yi-350-500mA.

4) Phantsi kweemeko zokungathwali mthwalo, ubuninzi bemfuno yangoku yi-5mA.

5) Nika amanqanaba amahlanu ezicelo zamandla kwi-PD (Isixhobo saMandla) ukusuka kwi-3.84 ukuya kwi-12.95W, kunye nobuninzi be-13W.

4.4 Wireless umsebenzi on-ibhodi Ethernet Wireless umsebenzi yenye inzuzo kwi-ibhodi Ethernet.I-WiFi nayo inomahluko wokusetyenziswa kweemoto - WAVE (UFikelelo olungenazingcingo kwiiNdawo zeMoto) Ukuqaliswa kwe-Ethernet ekwibhodi ngokungathandabuzekiyo iya kuba yeyona nto ilungileyo yokukhuthaza ukungeniswa kobuchwephesha bonxibelelwano obungenazingcingo WAVE kwibala lezemoto, elibonelela ngesiseko somzimba. ukuphunyezwa kwee-audio kunye nevidiyo kunye neemephu zenkcazo ephezulu ekunxibelelaneni kwexesha langempela, kwaye inika kwakhona indawo yokucinga ngakumbi yokusetyenziswa kweteknoloji ye-V2X.
