DP83848CVVX/NOPB Asalin Kayan Wutar Lantarki na IC Chip Integrated Circuit

DP83848CVVX/NOPB Asalin Kayan Wutar Lantarki na IC Chip Haɗe-haɗe da Hoto

taƙaitaccen bayanin:

Chip ɗin PHY shine da'ira-dijital hybrid kewaye, wanda ke da alhakin karɓar siginar analog kamar wutar lantarki da haske.Bayan ƙaddamarwa da juyawa A/D, ana aika siginar zuwa guntu na MAC don aiki ta hanyar MII interface.Gabaɗaya, kwakwalwan kwamfuta na MAC su ne da'irori na dijital.Layer na zahiri yana ayyana siginar lantarki da na gani, matsayin layi, nunin agogo, ɓoye bayanai da da'irori da ake buƙata don watsa bayanai da liyafar, kuma yana ba da daidaitattun musaya zuwa na'urorin haɗin bayanan bayanai.Ana kiran guntu Layer na zahiri PHY.
