Kufotokozera mwachidule:

Yoyenera kumadera ovuta a mafakitale, DP83822 ndi yolimba kwambiri, yotsika mphamvu imodzi yokhala ndi doko 10/100 Mbps Ethernet PHY.Imapereka ntchito zonse zosanjikiza zomwe zimafunikira kuti zitumize ndikulandila zingwe pazingwe zopotoka, kapena kulumikiza ku transceiver yakunja ya fiber optic.Kuphatikiza apo, DP83822 imapereka mwayi wolumikizana ndi MAC kudzera mu mawonekedwe a MII, RMII, kapena RGMII.

DP83822 imapereka zida zowunikira chingwe chophatikizika, kudziyesa-yekha, ndi luso lopumira kuti mugwiritse ntchito mosavuta.Imathandizira ma fieldbus angapo amakampani ndikuzindikira kwake kolumikizana mwachangu komanso Auto-MDIX m'njira zokakamiza.

DP83822 imapereka njira yatsopano komanso yolimba yochepetsera kugwiritsa ntchito mphamvu kudzera mu EEE, WoL ndi njira zina zopulumutsira mphamvu.

The DP83822 ndi mbali wolemera ndi pini-to-pini upgradeable njira kwa TLK105, TLK106, TLK105L ndi TLK106L 10/100 Mbps Efaneti PHYs.

DP83822 imabwera mu 32-pini 5.00-mm × 5.00-mm VQFN phukusi.

Transceiver

Ethernet Fiber Optic Transceiver.
The Ethernet fiber optic transceiver ndi njira ziwiri zosinthira zowonekera zomwe zimapereka zizindikiro za data za Ethernet ku zizindikiro za data za fiber optic, zomwe zimalola kuti zizindikiro za Ethernet zitumizidwe pamizere ya fiber optic kuti zidutse malire a mtunda wa 100m, zomwe zimapangitsa kuti intaneti ya Ethernet iwonongeke kwambiri.Kulankhulana kwa data ya Fiber optic kumakhala ndi mtunda wautali wolumikizana, kulumikizana kwakukulu kwa data, ndipo sikungasokonezedwe.
Optical fiber yalowa mumayendedwe onse amoyo pamilingo yonse.Monga momwe makina oyambira ochezera amatengera kulumikizana kwa chingwe, kutuluka kwa ma transceivers a fiber optic kumatsimikizira kuti ma siginecha amagetsi ndi ma fiber optic amatha kutembenuzidwira wina ndi mnzake bwino ndipo ali oyenera kulumikizana ndi matelefoni, kuwulutsa, ma network a Broadband, ndi malo ena a Ethernet omwe amafunikira kwambiri. liwiro, kuchuluka kwa data, komanso magwiridwe antchito komanso kudalirika.

Ethernet PHY

Kodi Ethernet PHY ndi chiyani:
PHY (Physical), yomwe imatha kutchedwa Port Physical Layer m'Chitchaina, ndi chidule cha mawonekedwe a OSI.Ndipo Ethernet ndi chipangizo chomwe chimagwiritsa ntchito mawonekedwe a OSI.Efaneti PHY ndi chip chomwe chimatumiza ndi kulandira mafelemu a data a Efaneti (mafelemu).

Ntchito Zofunika

1. Kutumiza deta: Pamene PHY imatumiza deta, imalandira deta yotumizidwa ndi MAC.Kenako imatembenuza deta yofananira kukhala serial stream data kenako ndikuyika detayo molingana ndi malamulo osungira osanjikiza.Pomaliza, imakhala chizindikiro cha analogi ndikutumiza deta.2.
2. PHY imakhalanso ndi ntchito yofunikira yogwiritsira ntchito gawo la CSMA / CD ntchito.3.
3. PHY imaperekanso ntchito yofunikira yogwirizanitsa ndi chipangizo kumbali inayo ndikuwonetsa momwe kugwirizana kwake kulili panopa komanso ntchito yogwirira ntchito kudzera mu ma LED.Tikalumikiza khadi la netiweki ku chingwe, PHY nthawi zonse imatulutsa ma sign kuti azindikire kukhalapo kwa zida kumbali inayo, zomwe zimalumikizana wina ndi mnzake mu "chilankhulo" chokhazikika kukambirana ndikuzindikira liwiro la kulumikizana, mawonekedwe a duplex, ngati gwiritsani ntchito control control ndi zina zotero.Childs, zotsatira za kukambirana uku ndi liwiro pazipita ndi yabwino duplex mode kuti akhoza mothandizidwa ndi zipangizo zonse.
