PRODUCT OVERVIEW

INTRODUCTION

The KS8910 10Base-T/100Base-TX Ethernet transceiver is fully compliant with the IEEE 802.3u specification,
provides configurable 100Mbs support for Category 5 unshielded twisted pair (UTP) and supports 10Mbs operation
on Category 3 UTP or Category 5 UTP. The transceiver provides an electrical interface between the Media
Independent Interface (MII) of the Media Access Controller (MAC) and the physical wire pair, and includes support
for the basic and extended register set of station management registers.
The Transceiver provides compatibility with full-duplex Ethernet and Fast Ethernet networks making it suitable for
applications such as switched hubs. Advanced features include Auto-Negotiation for enabling automatic
configuration of network characteristics as well as automatic power-down mode for reduced power consumption.
Functions provided by the transceiver include encoding and decoding of the serial data stream and delimiters, level
conversion, collision detection, signal quality error and link integrity testing, jabber control, and loopback testing.
The device also provides outputs for receive, transmit, collision, speed and link test LEDs.
The new 100-Mbit/s implementation of Ethernet increases the capacity of a network by a factor of ten while using
existing twisted-pair wiring. By maintaining the Media Access Control (MAC) layer and the CSMA/CD protocol
unchanged, network administrators can quickly deploy newer and faster implementations. This approach also
lowers cost of deployment since it allows re-use of existing software applications while supporting both 100- and
10-Mbit/s speeds, and new products may be deployed into transition markets.
