2. Application Circuits
LITELINK can be used with telephone networks
worldwide. Some public telephone networks, notably
in North America and Japan require a resistive line
termination. Other telephone networks, such as in
Europe, China 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.

The application circuits that follow address both types
of line termination models. A reactive termination
application circuit that describes the TBR-21
implementation is shown
circuit can be easily adapted for other reactive
termination needs.
