DP83848I PHYTER^®- Industrial Temperature

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

General Description

Features

The DP83848I is a robust fully featured 10/100 single

port Physical Layer device offering low power con-

sumption, including several intelligent power down

states. These low power modes increase overall prod-

uct reliability due to decreased power dissipation. Sup-

porting multiple intelligent power modes allows the

application to use the absolute minimum amount of

power needed for operation. In addition to low power,

the DP83848I is optimized for cable length perfor-

mance far exceeding IEEE specifications.

•

Low-power 3.3V, 0.18µm CMOS technology

Low power consumption < 270mW Typical

3.3V MAC Interface

Auto-MDIX for 10/100 Mb/s

Energy Detection Mode

25 MHz clock out

SNI Interface (configurable)

RMII Rev. 1.2 Interface (configurable)

MII Serial Management Interface (MDC and MDIO)

IEEE 802.3u MII

The DP83848I includes a 25MHz clock out. This

means that the application can be designed with a

minimum of external parts, which in turn results in the

lowest possible total cost of the solution.

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

IEEE 1149.1 JTAG

The DP83848I easily interfaces to twisted pair media

via an external transformer and fully supports JTAG

IEEE specification 1149.1 for ease of manufacturing.

Additionally 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 com-

pensation

The DP83848I features integrated sublayers to sup-

port both 10BASE-T and 100BASE-TX Ethernet proto-

cols, which ensures compatibility and interoperability

with all other standards based Ethernet solutions.

•

Error-free Operation up to 150 meters

Programmable LED support Link, 10 /100 Mb/s Mode, Activ-

ity, and Collision Detect

The DP83848I is offered in a small form factor (48 pin

LQFP) so that a minimum of board space is needed.

•

Single register access for complete PHY status

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

48-pin LQFP package (7mm) x (7mm)
