Applications
LAN Switch
The PI3L100 was designed to switch between various
standards such as 10Base-T, 100Base-T, 100VG-
AnyLAN, and Token Ring. Also general purpose appli-
cations such as loopback, line termination, and line
clamps that might normally use mechanical relays are
also ideal uses for this LAN Switch (see Figure 1).
Generally speaking, this LAN Switch can be used
for data rates to 200 Mbps and data signal levels from 0V
to 3.6V.

Signal Distortion
Distortion of the input signal is equated to 20LOG
varies is critical to low distortion. It should also be noted
that increasing the data rate increases harmonic distor-
tion which also effects the signal amplitude.
