DP83849C PHYTER® DUAL Commercial Temperature

Dual Port 10/100 Mb/s Ethernet Physical Layer Transceiver

Features

General Description

•

Low-power 3.3V, 0.18µm CMOS technology

Low power consumption <600mW Typical

3.3V MAC Interface

The number of applications requiring Ethernet Con-

nectivity continues to expand. Along with this

increased market demand is a change in application

requirements. Where single channel Ethernet used to

be sufficient, many applications such as wireless

remote base stations and industrial networking now

require DUAL Port functionality for redundancy or sys-

tem management.

The DP83849C is a highly reliable, feature rich device

perfectly suited for commercial or industrial applica-

tions enabling Ethernet on the factory floor. The

DP83849C features two fully independent 10/100 ports

for multi-port applications.

The DP83849C provides optimum flexibility in MPU

selection by supporting both MII and RMII interfaces.

In addition this device includes a powerful new diag-

nostics tool to ensure initial network operation and

maintenance. In addition to the TDR scheme, com-

monly used for detecting faults during installation,

NATIONAL’s innovative cable diagnostics provides for

real time continuous monitoring of the link quality. This

allows the system designer to implement a fault pre-

diction mechanism to detect and warn of changing or

deteriorating link conditions.

With the DP83849C, National Semiconductor contin-

ues to build on its Ethernet expertise and leadership

position by providing a powerful combination of fea-

tures and flexibility, easing Ethernet implementation for

the system designer.
