DP83848C PHYTER^®- Commercial Temperature

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

General Description

Features

The DP83848C 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.

•

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)

The DP83848C 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.

RMII Rev. 1.2 Interface (configurable)

MII Serial Management Interface (MDC and MDIO)

IEEE 802.3u MII

The DP83848C easily interfaces to twisted pair media

via an external transformer. Both MII and RMII are

supported ensuring ease and flexibility of design.

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

The DP83848C 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.

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

layer with adaptive equalization and Baseline Wander com-

pensation

•

Error-free Operation up to 137 meters

The DP83848C is offered in a small form factor (48 pin

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

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

ity, and Collision Detect
