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.

10Base-T

10 Mbps

100Base-T

100VG-AnyLAN

25 Mbps

Applications

3.6V. Ideally an input voltage between 0.2V and 3.6V will

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.
