DP83848J PHYTER® Mini LS

Commercial Temperature Single Port 10/100 Ethernet

Transceiver

General Description

Features

The DP83848J addresses the quality, reliability and small

form factor required for space sensitive applications in

embedded systems.

•

Low-power 3.3V, 0.18µm CMOS technology

Auto-MDIX for 10/100 Mb/s

Energy Detection Mode

The DP83848J offers performance far exceeding the

IEEE specifications, with superior interoperability and

industry leading performance beyond 137m of Cat-V

cable. The DP83848J also offers Auto-MDIX to remove

cabling complications. DP83848J has superior ESD pro-

tection, greater than 4KV Human Body Model, providing

extremely high reliability and robust operation, ensuring a

high level performance in all applications.

3.3V MAC Interface

RMII Rev. 1.2 Interface (configurable)

MII Interface

MII serial management interface (MDC and MDIO)

IEEE 802.3u Auto-Negotiation and Parallel Detection

IEEE 802.3u ENDEC, 10BASE-T transceivers and filters

IEEE 802.3u PCS, 100BASE-TX transceivers and filters

DP83848J offers two flexible LED indicators - one for Link

and the other for Speed. In addition, both MII and RMII

are supported ensuring ease and flexibility of design.

Integrated ANSI X3.263 compliant TP-PMD physical sub-

layer with adaptive equalization and Baseline Wander

compensation

The DP83848J is offered in a tiny 6mm x 6mm LLP 40-pin

package and is ideal for industrial controls, building/fac-

tory automation, transportation, test equipment and wire-

less base stations.

•

Error-free Operation beyond 137 meters

ESD protection - greater than 4KV Human body model

Configurable LED for link and activity

Applications

Single register access for complete PHY status

10/100 Mb/s packet BIST (Built in Self Test)

40 pin LLP package (6mm) x (6mm) x (0.8mm)
