DP83846A DsPHYTER — Single 10/100 Ethernet Transceiver
General Description
The DP83846A is a full feature single Physical Layer
device with integrated PMD sublayers to support both
10BASE-T and 100BASE-TX Ethernet protocols over Cat-
egory 3 (10 Mb/s) or Category 5 Unsheilded twisted pair
cables.
The DP83846A is designed for easy implementation of
10/100 Mb/s Ethernet home or office solutions. It interfaces
to Twisted Pair media via an external transformer. This
device interfaces directly to MAC devices through the IEEE
802.3u standard Media Independent Interface (MII) ensur-
ing interoperability between products from different ven-
dors.
The DP83846A utilizes on chip Digital Signal Processing
(DSP) technology and digital Phase Lock Loops (PLLs) for
robust performance under all operating conditions,
enhanced noise immunity, and lower external component
count when compared to analog solutions.
