10/100BASE Hex/Octal Ethernet Transceivers
Product Overview
With the proliferation of PCs and other Internet
appliances, the need for faster data transmission
is becoming more and more of a necessity. Intel,
a leader in Fast Ethernet technology, offers
low-power, single-chip Hex/Octal 10BASE-T
and 100BASE-TX/FX PHY products, bringing
robust Cable Discharge Event (CDE) performance
to networking systems such as switches and
multi-port Network Interface Cards (NICs).
The five transceivers in this product family,
LXT9761, LXT9781, LXT9762, LXT9782, and
LXT9763, are advanced 6-port and 8-port PHY
transceivers incorporating Intel鈥檚 Optimal Signal
Processing (OSP) architecture. OSP is an ideal
combination of digital signal processing and
analog design techniques developed to improve
die size, power consumption, performance, relia-
bility, and testability.
Through this architecture, an Intel Hex/Octal
10/100BASE PHY provides low-power copper
and fiber optic Ethernet connectivity. Interfaces
available in this product family include the standard
Media Independent Interface (MII), Serial MII
(SMII), and Reduced MII (RMII), allowing switch
ASIC designs to take advantage of low pin-count
PHY interfaces.
The Intel family of 10/100BASE Hex/Octal
Ethernet transceivers can provide significant
savings for high-density switch and router appli-
cations. With one of the broadest Ethernet product
lines in the industry, Intel stands ready to deliver
the 10Mbps, 100Mbps and 1000Mbps devices
OEMs require to meet their customers鈥?needs.
