LITELINK III Evaluation Board Users Guide
2. Setup
This section describes setting up the LITELINK III
evaluation board prior to use.
2.1 Connection
The LITELINK III evaluation board uses two 0.1 inch
(2.54 mm) pin headers for input and output connec-
tions, J1 and J2. Clare recommends you construct
header jumpers to bring the connections out to your
circuit in development

4. Design Notes
1. The default gain setting at the factory is 0 dB.
2. OH must be de-asserted (set logic high) once at
5. Worldwide Operation
LITELINK III evaluation board AC termination charac-
teristics may be changed by changing stuffing options.

5.1 Stuffing Options
LITELINK III Evaluation Boards can be used to evalu-
ate LITELINK III circuits connected to several types of
host equipment and several types of telephone net-
works. This flexibility will often require changes to the
components in the circuit.
Select and implement a stuffing option as described
below:

Make all connections to the board before applying
power.
LITELINK III evaluation board circuit components
are sensitive to electro-static discharge (ESD). Use
normal ESD precautions when working with the
LITELINK III evaluation board.
Option
power-up for 50 ms to transfer internal gain trim
values within LITELINK III. This would be normal
operation in many applications.
