2. Application Circuits
LITELINK can be used with telephone networks world-
wide. Some public telephone networks, notably in
North America and Japan require resistive line temri-
nation. Other telephone networks in Europe and else-
where require reactive line termination.
The application circuits below address both line termi-
nation models. The reactive termination application
circuit (see Section 2.2 on page 8) describes a TBR-21
implementation. This circuit can be adapted easily for
other reactive termination needs. Worldwide applica-
tion of LITELINK is described more fully in Clare appli-
cation note AN-147, Worldwide Application of LITELINK.
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
part. Other compliance requirements may require a different part.
2Higher-noise power supplies may require substitution of a 220
H inductor,
Toko 380HB-2215 or similar. See the Power Quality section of Clare applica-
tion note AN-146, Guidelines for Effective LITELINK Designs for more informa-
tion.
3Optional for enhanced trans-hybrid loss, see “Trans-Hybrid Loss” on page 16.
