DP83847 DsPHYTER II 鈥?Single 10/100 Ethernet Transceiver
General Description
Features
The DP83847 is a full feature single Physical Layer device
s
Low-power 3.3V, 0.18碌m CMOS technology
with integrated PMD sublayers to support both 10BASE-T
s
Power consumption < 351mW (typical)
and 100BASE-TX Ethernet protocols over Category 3 (10
s
5V tolerant I/Os
Mb/s) or Category 5 unshielded twisted pair cables.
s
5V/3.3V MAC interface
The DP83847 is designed for easy implementation of
10/100 Mb/s Ethernet home or office solutions. It interfaces
