DP83848H PHYTER^®Mini - Extreme Single 10/100 Ethernet

Transceiver

Features

General Description

•

Low-power 3.3V, 0.18µm CMOS technology

Auto-MDIX for 10/100 Mb/s

The DP83848H PHYTER® Mini Extreme addresses the

high quality, high reliability and small form factor required

for rugged operation in space sensitive and thermally

demanding environments. This device is ideally suited for

industrial and motor control, building/factory automation,

automotive and test equipment applications.

Energy Detection Mode

3.3V MAC Interface

RMII Rev. 1.2 Interface (configurable)

MII Interface and MII serial management interface (MDC

and MDIO)

The DP83848H is designed from ground up for extreme

temperature performance, with a thermally efficient pack-

age ensuring reliable operation over an operating range of

-40C to 125C. Rigorously tested at both low temperature

and high temperature extremes, the device is ideal for out-

door environments and demanding factory floor conditions.

•

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

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

layer with adaptive equalization and Baseline Wander

compensation

The device offers performance beyond the IEEE specifica-

tions, with superior interoperability and industry leading

performance. The DP83848H offers Auto-MDIX to remove

cabling complications, superior ESD protection of greater

than 4KV HBM for greater reliability, and superior cable

length operation (greater than 137m) to provide a high

level of performance in all applications.

•

Error-free Operation up to 137 meters

ESD protection - 4KV Human body model

Configurable LED for link and activity

Supports system clock from oscillator

A number of system cost-reducing features have been

integrated that are not commonly found in other Ethernet

Physical layer products (PHYs). For example, the

DP83848H offers 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 MII and RMII are supported ensuring ease

and flexibility of design.

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)
