RTL8201CP-VD-LF Electronic IC Chip SINGLE-CHIP 10/100M FAST ETHERNET PHYCEIVER

RTL8201CP

SINGLE-CHIP/SINGLE-PORT 10/100M FAST ETHERNET PHYCEIVER (With Auto Crossover)

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 detection function, 10Base-Tx Encoder/Decoder, and Twisted-Pair Media Access Unit (TPMAU).

A PECL (Pseudo Emitter Coupled Logic) interface is supported to connect with an external 100Base-FX fiber optical transceiver. The chip utilizes an advanced CMOS process to meet low voltage and low power requirements. With on-chip DSP (Digital Signal Processing) technology, the chip provides excellent performance under all operating conditions.

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 Communication Riser), an Ethernet hub, and an Ethernet switch. In addition, it 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.
