RTL8201CP 概述

The RTL8201CP is a single-port PHYceiver with an MII (Media Independent Interface)/SNI (Serial Network Interface). The RTL8201CP 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 detection function, 10Base-Tx Encoder/Decoder, and Twisted Pair Media Access Unit (TPMAU).

The RTL8201CP can be used for applications such as those for a Network Interface Adapter, MAU (Media Access Unit), CNR (Communication and Network Riser), ACR (Advanced Communications Riser), an Ethernet hub, and an Ethernet switch. In addition, the RTL8201CP can be used in any embedded system with an Ethernet MAC that needs a UTP physical connection or Fiber PECL interface to an external 100Base-FX optical transceiver module.
