DP83847 DP83847 DsPHYTER II -Single 10/100 Ethernet Transceiver Literature Number: SNLS157 DP83847 DsPHYTER II — Single 10/100 Ethernet Transceiver
General Description Features The DP83847 is a full feature single Physical Layer device в–  Low-power 3.3V, 0.18Вµm CMOS technology
with integrated PMD sublayers to support both 10BASE-T в–  Power consumption < 351mW (typical)
and 100BASE-TX Ethernet protocols over Category 3 (10
в–  5V tolerant I/Os
Mb/s) or Category 5 unshielded twisted pair cables.
в–  5V/3.3V MAC interface
The DP83847 is designed for easy implementation of
10/100 Mb/s Ethernet home or office solutions. It interfaces в–  IEEE 802.3 ENDEC, 10BASE-T transceivers and filters
to Twisted Pair media via an external transformer. This в–  IEEE 802.3u PCS, 100BASE-TX transceivers and filters
device interfaces directly to MAC devices through the IEEE в–  IEEE 802.3 compliant Auto-Negotiation
802.3u standard Media Independent Interface (MII) ensuring interoperability between products from different ven-в–  Output edge rate control eliminates external filtering for
Transmit outputs
dors.
в– 
BaseLine Wander compensation
The DP83847 utilizes on chip Digital Signal Processing
(DSP) technology and digital Phase Lock Loops (PLLs) for в–  IEEE 802.3u MII (16 pins/port)
robust performance under all operating conditions, в–  LED support (Link, Rx, Tx, Duplex, Speed, Collision)
enhanced noise immunity, and lower external component
в–  Single register access for complete PHY status
count when compared to analog solutions.
в–  10/100 Mb/s packet loopback BIST (Built in Self Test) …
