Industrial Temperature Single Port 10/100 Ethernet Transceiver
General Description
Features
The DP83848T/K addresses the quality, reliability and
small form factor required for space sensitive applications
in embedded systems operating in the industrial tempera-
ture range.
The DP83848T/K offers performance far exceeding the
IEEE specifications, with superior interoperability and
industry leading performance beyond 137m of Cat-V
cable. The DP83848T/K also offers Auto-MDIX to remove
cabling complications. DP83848T/K has superior ESD pro-
tection, greater than 4KV Human Body Model, providing
extremely high reliability and robust operation, ensuring a
high level performance in all applications.
DP83848K offers two flexible LED indicators - one for Link
and the other for Speed.
A 25MHz clock out that eliminates the need and hence the
space and cost, of an additional Media Access Control
(MAC) clock
