DP83848M PHYTER^®Mini - Commercial Temperature

Single 10/100 Ethernet Transceiver

Features

General Description

•

Low-power 3.3V, 0.18µm CMOS technology

Auto-MDIX for 10/100 Mb/s

The DP83848M PHYTER Mini addresses the quality, reli-

ability and small form factor required for space sensitive

applications in embedded systems.

Energy Detection Mode

The device offers performance far exceeding the IEEE

specifications, with superior interoperability and industry

leading performance beyond 137m of Cat-V cable. The

3.3V MAC Interface

RMII Rev. 1.2 Interface (configurable)

DP83848M also offers Auto-MDIX to remove cabling com- • MII Interface

plications. DP83848M has superior ESD protection,

•

MII serial management interface (MDC and MDIO)

IEEE 802.3u Auto-Negotiation and Parallel Detection

greater than 4KV Human Body Model, providing extremely

high reliability and robust operation, ensuring a high level

performance in all applications.

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

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

National’s DP83848M incorporates a number of system

cost-reducing features not found on other supplier’s Physi-

cal layer products. For example, the DP83848M incorpo-

rates a 25MHz clock out that eliminates the need and

hence the space and cost, of an additional Media Access

Control (MAC) clock source component. In addition, both

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

layer with adaptive equalization and Baseline Wander

compensation

•

Error-free Operation up to 137 meters

MII and RMII are supported ensuring ease and flexibility of • ESD protection - 4KV Human body model

design.

•

Configurable LED for link and activity

The DP83848M is offered in a tiny 6mm x 6mm LLP 40-pin

package and is ideal for industrial controls, building/factory

automation, transportation, test equipment and wireless

base stations.

Supports system clock from oscillator
