Introduction

The ISL55185XEVAL1 board can be used to evaluate the new ISL5585 3.3volt SLIC. This platform supports the evaluation of the performance of the ISL5585 at volts with a 5 volt CODEC. The lab data presented in this application note had the following supplies voltages Vcc ISL5585 = 3.3V, Vcc CODEC = 5V, VBH = -100v and Vbl = -24v.

The ISL5585XEVAL1 evaluation board provides a complete evaluation system for the ISL5585 family of ringing SLICs. Included on the evaluation board is 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 ISL5585 in response to mode changes has been improved. The benefit to the application is reduction or more likely elimination of DET glitches when off hook events occur.

Voltage ratings for external components have been selected based on 100V device operation, therefore compatibility to lower voltage versions is guaranteed.

Getting Started

Your evaluation kit should contain application note AN1038 and the following hardware.

One ISL5585XEVAL1evaluation board. One ISL5585X device sample, already in board. One PLCC extraction tool. One cable assembly with multi colored conductors. One cable assembly with solid white conductors. The evaluation board should have the same appearance as the silk screen shown in Figure

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.

Limit the current on all power supplies to 100mA. Turn on the power supplies after the power cables are
attached to the evaluation boards.
