2. Application Circuits
LITELINK can be used with telephone networks
worldwide. Some public telephone networks, notably
in North America and Japan require resistive line
termination. Other telephone networks, as in Europe
and elsewhere, require a reactive line termination.
2.1 Resistive Termination Application Circuit
Figure 3. Resistive Termination Application Circuit Schematic
¹This design was tested and found to comply with FCC Part 68 with this
Sidactor. Other compliance requirements may require a different part.
²Higher-noise power supplies may require substitution of a 220 μH inductor,
Toko 380HB-2215 or similar. See the Power Quality section of Clare
application note AN-146,
more information.
³Optional for enhanced transhybrid loss.
