Commercial Temperature Single Port 10/100 Ethernet Transceiver
General Description
Features
The DP83848M/J addresses the quality, reliability and •
small form factor required for space sensitive applications _•
in embedded systems.
•
The DP83848M/J offers performance far exceeding the
IEEE specifications, with superior interoperability and
•
industry leading performance beyond 137m of Cat-V ^•
cable. The DP83848M/J also offers Auto-MDIX to remove •
cabling complications. DP83848M/J has superior ESD
pro-tection, greater than 4KV Human Body Model, provid-
•
ing extremely high reliability and robust operation, ensur- ^•
ing a high level performance in all applications.
•
Low-power 3.3V, 0.18µm CMOS technology
3.3V MAC Interface
Auto-MDIX for 10/100 Mb/s
Energy Detection Mode
MII Interface
MII serial management interface (MDC and MDIO)
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
DP83848J 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
