DP83848M PHYTER^® Mini - Commercial Temperature
Single 10/100 Ethernet Transceiver
General Description
Features
The DP83848M PHYTER Mini addresses the quality, reli- •
ability and small form factor required for space sensitive _•
applications in embedded systems.
•
The device offers performance far exceeding the IEEE
specifications, with superior interoperability and industry
•
leading performance beyond 137m of Cat-V cable. The ^•
DP83848M also offers Auto-MDIX to remove cabling com- •
plications. DP83848M has superior ESD protection, _•
greater than 4KV Human Body Model, providing extremely
high reliability and robust operation, ensuring a high level ^•
performance in all applications.
•
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 ^•
MII and RMII are supported ensuring ease and flexibility of •
design.
•
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.
