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 package 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 outdoor environments and
demanding factory floor conditions.
The device offers performance beyond the IEEE specifications, 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. In addition, both MII and RMII are supported ensuring ease and
flexibility of design.
DP83848H is offered in a small 6mm x 6mm LLP 40-pin package.
