RTL8201CL 概述

The RTL8201CL is a single-port PHYceiver with an MII (Media Independent Interface)/SNI (Serial Network Interface). The RTL8201CL 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), 10Base-Tx Encoder/Decoder, and Twisted Pair Media Access Unit (TPMAU).

The RTL8201CL 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 RTL8201CL 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.
