The first Unified Gigabit Ethernet LAN
Switch solution in the world is ideal for high-end notebook
computers which offer docking station options integrating
Ethernet functionality. This single low-cost device can replace
the 2nd PHY that resides on the docking station thereby saving
customers $7 per unit.
Our PI3L301D switch is bidirectional
and beats the IEEE802.3-Gigabit Ethernet return loss specification
with a minimum of 2dB of margin over the entire frequency
band.
The device multiplexes eight pairs of differential outputs from a Gigabit
Ethernet transceiver into one of two corresponding 8bit outputs.
This 16 to 8bit mux/demux functionality and performance enables notebook
PC design engineers to eliminate an entire Gigabit Ethernet transceiver,
thus resulting in a platform cost savings of $5 to $7 in every notebook
PC and docking station solution.
Although ideally suited for Gigabit Ethernet and Fibre Channel applications,
the revolutionary PI3L301D LAN switch technology is useful wherever a
design engineer needs to switch differential pairs of LVDS or LVPECL
signals to support signalling line rates of Sonet OC-12 (622Mbit/s).
The low-voltage, low-on-resistance device provides customers with minimum
distortion, low output skew and high-speed signal routing.
This PI3L301D multiplexer/demultiplexer switch is a passive switching
element implemented in low-power CMOS.
It works by aligning the differential signals from the Gigabit Ethernet
transceiver in such a way as to reduce the crossing over of traces, which
can make the Ethernet signals susceptible to crosstalk and other noise.
It can be deployed anywhere there is a need for high-speed Gigabit Ethernet
routing for such end products as high-end notebook computers, PCMCIA
cards, switching-routers, servers, and SAN.
