DP83848H PHYTER^® Mini - Extreme Temperature
Single 10/100 Ethernet Transceiver
General Description
Features
The DP83848H PHYTER® Mini Extreme addresses the ^{• Low-power 3.3V, 0.18µm CMOS technology}
high quality, high reliability and small form factor required _{• 3.3V MAC Interface}
for rugged operation in space sensitive and thermally
demanding environments. This device is ideally suited for
•
Auto-MDIX for 10/100 Mb/s
industrial and motor control, building/factory automation, ^{• Energy Detection Mode}
automotive and test equipment applications.
• MII Interface and MII serial management interface (MDC
The DP83848H is designed from ground up for extreme ^{and MDIO)}
temperature performance, with a thermally efficient pack- ^{• IEEE 802.3u Auto-Negotiation and Parallel Detection}
age ensuring reliable operation over an operating range of • IEEE 802.3u ENDEC, 10BASE-T transceivers and filters
-40C to 125C. Rigorously tested at both low temperature _{• IEEE 802.3u PCS, 100BASE-TX transceivers and filters}
and high temperature extremes, the device is ideal for out-
door environments and demanding factory floor conditions. ^{• Integrated ANSI X3.263 compliant TP-PMD physical sub-}
layer with adaptive equalization and Baseline Wander
The device offers performance beyond the IEEE specifica- compensation
tions, with superior interoperability and industry leading
performance. The DP83848H offers Auto-MDIX to remove
•
Error-free Operation up to 137 meters
cabling complications, superior ESD protection of greater • ESD protection - 4KV Human body model
than 4KV HBM for greater reliability, and superior cable _{• LED support for Link}
length operation (greater than 137m) to provide a high
level of performance in all applications.
•
Supports system clock from oscillator
• Single register access for complete PHY status
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 ^{• 40 pin LLP package (6mm) x (6mm) x (0.8mm)}
DP83848H offers a 25MHz clock out that eliminates the
need and hence the space and cost, of an additional Applications
Media Access Control (MAC) clock source component.
• Peripheral devices
DP83848H is offered in a small 6mm x 6mm LLP 40-pin _{• Mobile devices}
package.
• Factory and building automation
