HC5518XEVAL Evaluation Board User’s Guide

Introduction
The HC5518XEVAL evaluation
board provides a complete
evaluation system for the HC55185
family of ringing SLICs. The
evaluation board design consists of the HC55185 device
application circuit, a single +5V CODEC for line circuit
evaluations and on board logic for stand alone operation. The
evaluation boards have been designed to support back to
back operation, providing further insight to the complete signal
path and solution.
The transient behavior of the SLIC in response to mode
changes has been signi?cantly improved with the HC55185
design. The bene?t to the application is reduction or more
likely elimination of DET glitches when off hook events
occur. In addition to internal circuit modi?cations, the change
of the C FB value contributes to this functional improvement.
Please reference the HC55185 data sheet for detailed
information regarding this feature.
Getting Started
Your evaluation kit should contain this user’s guide and the
following hardware.
1. One HC5518XEVAL evaluation board.
2. At least one HC55185 device sample, already in board.
3. One PLCC extraction tool.
4. One cable assembly with multi colored conductors.
5. One cable assembly with solid white conductors.
The evaluation board should have the same appearance as
the silk screen shown in Figure 1.
Applying Power to the Evaluation Board
Here are a few safeguards with power sequencing until you
are accustomed to using the high voltages required by the
devices.
1. Limit the current on all power supplies to 100mA.
2. Turn on the power supplies after the power cables are
attached to the evaluation boards.
Voltage ratings for external components have been selected
based on 100V device operation, therefore compatibility to
lower voltage versions is guaranteed.
