Ibikoresho bya elegitoronike IC Chips Yuzuzanya Yuzuzanya IC DP83822IFRHBR

ibisobanuro bigufi:

Nibyiza kubidukikije bikabije byinganda, DP83822 ni ultra-robust, imbaraga nkeya imwe-icyambu 10/100 Mbps Ethernet PHY.Itanga ibikorwa byose bifatika bikenewe kugirango wohereze kandi wakire amakuru hejuru yinsinga zisanzwe zigoretse, cyangwa uhuze na fibre optique ya transiberi.Byongeye kandi, DP83822 itanga ihinduka kugirango ihuze MAC ikoresheje MII isanzwe, RMII, cyangwa RGMII.

Ibicuruzwa

DP83822 itanga ibikoresho byo kwisuzumisha byahujwe, byubatswe-byo-kwipimisha, hamwe nubushobozi bwo gusubira inyuma kugirango byoroshye gukoresha.Ifasha inganda nyinshi zinganda hamwe nihuta ryihuse-hasi kimwe na Auto-MDIX muburyo bwagahato.

DP83822 itanga uburyo bushya kandi bukomeye bwo kugabanya gukoresha amashanyarazi binyuze muri EEE, WoL nubundi buryo bwo kuzigama ingufu zishobora gukoreshwa.

DP83822 nuburyo bukize kandi pin-to-pin ishobora kuzamurwa kuri TLK105, TLK106, TLK105L na TLK106L 10/100 Mbps Ethernet PHYs.

DP83822 ije muri 32-pin 5.00-mm × 5.00-mm ya VQFN.

Transceiver

Ethernet Fibre Optic Transceiver.
Ethernet fibre optique transceiver ninzira zibiri zihinduranya zitanga ibimenyetso bya Ethernet kubimenyetso byamakuru ya fibre optique, bigatuma ibimenyetso bya Ethernet byandikirwa kumurongo wa fibre optique kugirango bice intera 100m yoherejwe, bigatuma umuyoboro wa Ethernet waguka cyane.Itumanaho rya fibre optique rifite ibiranga intera ndende itumanaho, ubushobozi bwitumanaho rinini, kandi ntabwo byoroshye kwivanga.
Fibre optique yinjiye mubice byose byubuzima mu nzego zose.Nkuko sisitemu yumwimerere ya sisitemu ishingiye ku itumanaho rya kabili, kugaragara kwa fibre optique ituma ibyuma byamashanyarazi nibimenyetso bya fibre optique bishobora guhindurwamo neza kandi bikwiriye itumanaho, gutangaza amakuru, imiyoboro migari, nibindi bidukikije bya Ethernet bisaba hejuru umuvuduko, amakuru menshi yimodoka, hamwe nibikorwa byinshi kandi byizewe.

Ethernet PHY

Niki Ethernet PHY:
PHY (Physical), ishobora kwitwa Port Physical Layer mu Gishinwa, ni amagambo ahinnye ya OSI yerekana umubiri.Kandi Ethernet nigikoresho gikora urwego rwumubiri rwa moderi ya OSI.Ethernet PHY ni chip yohereza kandi yakira amakuru ya Ethernet amakadiri (amakadiri).

Imikorere y'ingenzi

1. Kohereza amakuru: Iyo PHY yohereje amakuru, yakira amakuru yoherejwe na MAC.Hanyuma ihindura amakuru abangikanye muburyo bwimikorere hanyuma ikabika amakuru ukurikije amategeko agenga kodegisi.Hanyuma, ihinduka ikimenyetso kimwe kandi ikohereza amakuru hanze.2.
2. PHY ifite kandi umurimo wingenzi wo gushyira mubikorwa igice cya CSMA / CD.3.
3. PHY itanga kandi umurimo wingenzi wo guhuza nigikoresho kurundi ruhande kandi ikerekana uko ihagaze ubu nuburyo ikora binyuze muri LED.Iyo duhuza ikarita y'urusobekerane, umugozi wa PHY uhora utera ibimenyetso kugirango tumenye ko hari ibikoresho kurundi ruhande, bivugana hagati yururimi "rusanzwe" kugirango tuganire kandi tumenye umuvuduko wihuza, uburyo bwa duplex, niba koresha kugenzura imigendekere nibindi.Mubisanzwe, ibisubizo byibi biganiro ni umuvuduko ntarengwa nuburyo bwiza bwa duplex bushobora gushyigikirwa nibikoresho byombi.
