Realtek RTL8201CL

The RTL8201CL is a 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), 10Base-Tx Encoder/Decoder and Twisted Pair Media Access Unit (TPMAU). A PECL interface is supported to connect with an external 100Base-FX fiber optical transceiver. The chip is fabricated with an advanced CMOS process to meet low voltage and low power requirements. Further more, it is developed with on chip Digital Signal Processing technology to ensure excellent performance under all operating conditions. The RTL8201CL can be used as a Network Interface Adapter, MAU, CNR, ACR, Ethernet Hub, and Ethernet Switch. Additionally, it can also be used in any embedded system with an Ethernet MAC that needs a UTP physical connection or Fiber PECL interface to external 100Base-FX optical transceiver module.
