Single Port 10/100 Mb/s Ethernet Physical Layer Transceiver
General Description
Features
The number of applications requiring ethernet connec- ^{• Extreme Temperature from -40 °C to 125 °C}
tivity continues to increase. Along with this increased _{• Low-power 3.3V, 0.18µm CMOS technology}
market demand is a change in application require-
ments. The DP83848YB was designed to allow ether-
•
Low power consumption < 270mW Typical
net connectivity in the harshest environments. Our ^{• 3.3V MAC Interface}
device meets IEEE 802.3u standards over an • Auto-MDIX for 10/100 Mb/s
EXTREME temperature range of -40°C to 125 °C. This _{• Energy Detection Mode}
device is ideally suited for harsh environments for
example wireless remote base stations, automo-

• IEEE 802.3u Auto-Negotiation and Parallel Detection
With the DP83848YB NATIONAL continues to build on
its Ethernet expertise and leadership position by pro- ^{• IEEE 802.3u ENDEC, 10BASE-T transceivers and filters}
viding the flexibility allowing for ease of implementation • IEEE 802.3u PCS, 100BASE-TX transceivers and filters
by the end user.
• IEEE 1149.1 JTAG
The DP83848YB features integrated sublayers to sup- • Integrated ANSI X3.263 compliant TP-PMD physical sub-
port both 10BASE-T and 100BASE-TX Ethernet proto- _{layer with adaptive equalization and Baseline Wander com-}
cols, which ensures compatibility and interoperability pensation
with all other standards based Ethernet solutions.
