General Description
●The RTL8201CP is a single-chip/single-port PHYceiver with an MII (Media Independent Interface)/SNI (Serial Network Interface). It implements all 10/100M Ethernet Physical-layer functions including the Physical Coding Sublayer (PCS), Physical Medium Attachment (PMA), Twisted Pair Physical Medium Dependent Sublayer (TP-PMD), with an auto crossover detectionfunction, 10Base-Tx Encoder/Decoder, and Twisted-Pair Media Access Unit (TPMAU).
●Features
●The Realtek RTL8201CP is a Fast Ethernet PHYceiver with selectableMII or SNI interface to the MAC chip. It provides the following features:
●Pin-to-pin compatible with the RTL8201BL
●Supports MII and 7-wireSNI (Serial Network Interface)
●10/100Mbps operation
●Full/half duplex operation
●Twisted pair or fiber mode output
●Auto-Negotiation
