GENERAL DESCRIPTION
The NetPHY-1 device is a physical-layer, single-chip,
low-power transceiver for 100BASE-TX, 100BASE-FX,
and 10BASE-T operations. On the media side, it pro-
vides a direct interface to Fiber Media for 100BASE-FX
Fast Ethernet, Unshielded Twisted Pair Category 5
Cable (UTP5) for 100BASE-TX Fast Ethernet, or
UTP5/UTP3 Cable for 10BASE-T Ethernet. Through
the IEEE 802.3u Media Independent Interface (MII),
the NetPHY-1 device connects to the Medium Access
Control (MAC) layer, ensuring a high interoperability
among products from different vendors.
The NetPHY-1 device uses a low-power, high-perfor-
mance CMOS process. It contains the entire physical
layer functions of 100BASE-FX and 100BASE-TX as
defined by the IEEE 802.3u standard, including the
Physical Coding Sublayer (PCS), Physical Medium
Attachment (PMA), 100BASE-TX Twisted Pair Physical
Medium Dependent (TP-PMD) sublayer, and a
10BASE-T Encoder/Decoder (ENDEC). The NetPHY-1
device provides strong support for the Auto-Negotiation
function utilizing automatic media speed and protocol
selection. The NetPHY-1 device incorporates an inter-
nal wave-shaping filter to control rise/fall time, eliminat-
ing the need for external filtering on the 10/100
Mbps signals.
