DP83848H PHYTER^® Mini - Extreme Single 10/100 Ethernet
Transceiver
General Description
Features
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.
•
Low-power 3.3V, 0.18µm CMOS technology
Auto-MDIX for 10/100 Mb/s
Energy Detection Mode
3.3V MAC Interface
RMII Rev. 1.2 Interface (configurable)
The DP83848H is designed from ground up for extreme ^{• MII Interface and MII serial management interface (MDC}
temperature performance, with a thermally efficient pack- ^{and MDIO)}
age ensuring reliable operation over an operating range of _{• IEEE 802.3u Auto-Negotiation and Parallel Detection}
-40C to 125C. Rigorously tested at both low temperature
and high temperature extremes, the device is ideal for out-
•
IEEE 802.3u ENDEC, 10BASE-T transceivers and filters
door environments and demanding factory floor conditions. ^{• IEEE 802.3u PCS, 100BASE-TX transceivers and filters}
The device offers performance beyond the IEEE specifica- ^•
tions, with superior interoperability and industry leading
performance. The DP83848H offers Auto-MDIX to remove
Integrated ANSI X3.263 compliant TP-PMD physical sub-
layer with adaptive equalization and Baseline Wander
compensation
cabling complications, superior ESD protection of greater • Error-free Operation up to 137 meters
than 4KV HBM for greater reliability, and superior cable _{• ESD protection - 4KV Human body model}
length operation (greater than 137m) to provide a high
level of performance in all applications.
• Configurable LED for link and activity
• Supports system clock from oscillator
A number of system cost-reducing features have been
integrated that are not commonly found in other Ethernet ^{• Single register access for complete PHY status}
Physical layer products (PHYs). For example, the • 10/100 Mb/s packet BIST (Built in Self Test)
DP83848H offers a 25MHz clock out that eliminates the _{• 40 pin LLP package (6mm) x (6mm) x (0.8mm)}
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
Applications
and flexibility of design.
• Peripheral devices
DP83848H is offered in a small 6mm x 6mm LLP 40-pin ^{• Mobile devices}
package.
• Factory and building automation
• Basestations
