Low-power 3.3V, 0.18µm CMOS technology
Auto-MDIX for 10/100 Mb/s
The DP83848M PHYTER Mini addresses the quality, reli-
ability and small form factor required for space sensitive
applications in embedded systems.
Energy Detection Mode
The device offers performance far exceeding the IEEE
specifications, with superior interoperability and industry
leading performance beyond 137m of Cat-V cable. The

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
