Izingxenye Ze-elekthronikhi Ama-IC Chips Amasekhethi Ahlanganisiwe IC DP83822IFRHBR

Izingxenye Zogesi Ama-IC Chips Amasekhethi Ahlanganisiwe IC DP83822IFRHBR Isithombe Esifakiwe
  • Izingxenye Ze-elekthronikhi Ama-IC Chips Amasekhethi Ahlanganisiwe IC DP83822IFRHBR

incazelo emfushane:

Ilungele izindawo zezimboni ezinokhahlo, i-DP83822 iyimbobo eyodwa enamandla, enamandla aphansi engu-10/100 Mbps Ethernet PHY.Inikeza yonke imisebenzi yesendlalelo esibonakalayo edingekayo ukuze kudluliswe futhi kwamukelwe idatha ngezintambo ezisontekile ezisontekile, noma ukuxhuma ku-transceiver ye-fiber optic yangaphandle.Ukwengeza, i-DP83822 ihlinzeka ngokuguquguquka ukuze uxhumeke ku-MAC ngokusebenzisa isixhumi esibonakalayo se-MII, RMII, noma i-RGMII.

Ilungele izindawo zezimboni ezinokhahlo, i-DP83822 iyimbobo eyodwa enamandla, enamandla aphansi engu-10/100 Mbps Ethernet PHY.Inikeza yonke imisebenzi yesendlalelo esibonakalayo edingekayo ukuze kudluliswe futhi kwamukelwe idatha ngezintambo ezisontekile ezisontekile, noma ukuxhuma ku-transceiver ye-fiber optic yangaphandle.Ukwengeza, i-DP83822 ihlinzeka ngokuguquguquka ukuze uxhumeke ku-MAC ngokusebenzisa isixhumi esibonakalayo se-MII, RMII, noma i-RGMII.

I-DP83822 inikezela ngamathuluzi okuxilonga amakhebula adidiyelwe, ukuzihlola okwakhelwe ngaphakathi, namakhono we-loopback ukuze asetshenziswe kalula.Isekela ama-fieldbus amaningi ezimboni ngokutholwa kwayo ngokushesha kokuxhumanisa phansi kanye ne-Auto-MDIX ezindleleni eziphoqelelwe.

I-DP83822 inikeza indlela emisha neqinile yokunciphisa ukusetshenziswa kwamandla nge-EEE, i-WoL nezinye izindlela zokonga amandla ezihlelekayo.

I-DP83822 iyisici esicebile nephini-to-pin ethuthukisiwe inketho ye-TLK105, TLK106, TLK105L kanye ne-TLK106L 10/100 Mbps Ethernet PHYs.

I-DP83822 iza nephakheji ye-VQFN engu-32-pin 5.00-mm × 5.00-mm VQFN.

I-Transceiver

I-Ethernet Fiber Optic Transceiver.
I-Ethernet fiber optic transceiver iyisiguquli esinezinhlangothi ezimbili esisobala esihlinzeka ngezimpawu zedatha ye-Ethernet kumasiginali wedatha ye-fiber optic, okuvumela amasiginali we-Ethernet ukuthi adluliselwe phezu kwemigqa ye-fiber optic ukuze eqe umkhawulo webanga lokudlulisela elingu-100m, okwenza ukumbozwa kwenethiwekhi ye-Ethernet kunwetshwe kakhulu.Ukuxhumana kwedatha ye-Fiber optic kunezici zebanga elide lokuxhumana, umthamo wedatha enkulu yokuxhumana, futhi akulula ukuthikamezeka.
I-Optical fiber ingene kuzo zonke izigaba zokuphila kuwo wonke amazinga.Njengoba izinhlelo zenethiwekhi zangempela zisekelwe ekuxhumaneni kwezintambo, ukuvela kwe-fiber optic transceivers kuqinisekisa ukuthi amasignali kagesi kanye namasignali e-fiber optic angaguqulelwa komunye nomunye ngokushelelayo futhi afaneleka ezokuxhumana, ukusakaza, amanethiwekhi e-broadband, nezinye izindawo ze-Ethernet ezidinga ukuphakama. isivinini, ithrafikhi yedatha ephezulu, nokusebenza okuphezulu nokuthembeka.

I-Ethernet PHY

Yini i-Ethernet PHY:
I-PHY (Physical), engabizwa ngokuthi I-Port Physical Layer ngesi-Chinese, isifinyezo esivamile sesendlalelo esibonakalayo semodeli ye-OSI.Futhi i-Ethernet iyidivayisi esebenzisa isendlalelo esibonakalayo semodeli ye-OSI.I-Ethernet PHY iyi-chip ethumela futhi yamukele ozimele bedatha ye-Ethernet (ozimele).

Imisebenzi Ebalulekile

1. Ukuthumela idatha: Uma i-PHY ithumela idatha, ithola idatha edluliswa yi-MAC.Ibese iguqula idatha ehambisanayo ibe idatha yokusakaza yochungechunge bese ibhala ngekhodi idatha ngokuya ngemithetho yombhalo wekhodi wongqimba olubonakalayo.Ekugcineni, iba isignali ye-analog futhi ithumela idatha.2.
2. I-PHY futhi inomsebenzi obalulekile wokuqalisa ingxenye yomsebenzi we-CSMA/CD.3.
3. I-PHY iphinde inikeze umsebenzi obalulekile wokuxhuma nedivayisi ngakolunye uhlangothi futhi ibonise isimo sayo samanje sokuxhuma nesimo sokusebenza ngama-LED.Lapho sixhuma ikhadi lenethiwekhi kukhebula, i-PHY ihlale ishayela amasignali ukuze ibone ukuthi kukhona amadivaysi ngakolunye uhlangothi, axhumana wodwa “ngolimi” olujwayelekile ukuze kuxoxiswane futhi kunqunywe isivinini sokuxhuma, imodi eyi-duplex, ukuthi sebenzisa isilawuli sokugeleza nokunye.Ngokuvamile, umphumela walokhu kuxoxisana isivinini esiphezulu kanye nemodi ye-duplex engcono kakhulu engasekelwa yiwo womabili amadivayisi.
