General Description
The DP83848H PHYTER® Mini Extreme addresses the
high quality, high reliability and small form factor required
for rugged operation in space sensitive and thermally
demanding environments. This device is ideally suited for
industrial and motor control, building/factory automation,
automotive and test equipment applications.
The DP83848H is designed from ground up for extreme
temperature performance, with a thermally efficient pack-
age ensuring reliable operation over an operating range of
-40C to 125C. Rigorously tested at both low temperature
and high temperature extremes, the device is ideal for out-
door environments and demanding factory floor conditions.
The device offers performance beyond the IEEE specifica-
tions, with superior interoperability and industry leading
performance. The DP83848H offers Auto-MDIX to remove
cabling complications, superior ESD protection of greater
than 4KV HBM for greater reliability, and superior cable
length operation (greater than 137m) to provide a high
level of performance in all applications.
A number of system cost-reducing features have been
integrated that are not commonly found in other Ethernet
Physical
layer
products
(PHYs).
For
example,
the
DP83848H offers a 25MHz clock out that eliminates the
need and hence the space and cost, of an additional
Media Access Control (MAC) clock source component.
DP83848H is offered in a small 6mm x 6mm LLP 40-pin
package.
