DP83848Q

PHYTER Extended Temperature Single Port 10/100 Mb/s

Ethernet Physical Layer Transceiver

1.0 General Description

3.0 Features

The number of applications requiring Ethernet connectivity

continues to increase, driving Ethernet enabled devices into

harsher environments.

AEC-Q100 Grade 2

■

Extreme Temperature from -40°C to 105°C

Low-power 3.3V, 0.18µm CMOS technology

The DP83848Q was designed to meet the challenge of these

new applications with an extended temperature performance

that goes beyond the typical Industrial temperature range.

The DP83848Q is a highly reliable, feature rich, robust device

which meets IEEE 802.3u standards over an EXTENDED

temperature range of -40°C to 105°C. This device is ideally

suited for harsh environments such as automotive/transporta-

tion, wireless remote base stations,and industrial control ap-

plications.

Low power consumption <270mW Typical

3.3V MAC Interface

Auto-MDIX for 10/100 Mb/s

Energy Detection Mode

25 MHz clock out

RMII Rev. 1.2 Interface (configurable)

MII Serial Management Interface (MDC and MDIO)

IEEE 802.3u MII

It offers enhanced ESD protection and the choice of an MII or

RMII interface for maximum flexibility in MPU selection; all in

a 40 pin LLP package.

IEEE 802.3u Auto-Negotiation and Parallel Detection

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

The DP83848Q extends the leadership position of the

PHYTER family of devices with a wide operating temperature

range. The National Semiconductor line of PHYTER

transceivers builds on decades of Ethernet expertise to offer

the high performance and flexibility that allows the end user

an easy implementation tailored to meet these application

needs.

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

IEEE 1149.1 JTAG

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

layer with adaptive equalization and Baseline Wander

compensation

Error-free Operation up to 150 meters

■

Programmable LED support for Link and Activity

2.0 Applications

Single register access for complete PHY status

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

Automotive/Transportation
