Evaluation Kit User Manual for FX602
EV6020
1.3 Quick Start
This section provides instructions for users who wish to experiment immediately with the evaluation
kit. A fuller description of the kit and its use appears later in this document.
1.3.1 Setting-Up
THE EV6020 COMES PRE-CONFIGURED WITH AN FX602, SET FOR OPERATION AT 5.0V.
The board should be interconnected to a suitable µC control board with a 20-way flat cable, as shown
in the Block Diagram of Figure 1. If the EV6000 µC board is not used, then power will need to be
applied separately to the EV6020 evaluation kit through connector J3. An RJ11 (US style) phone jack
is provided for telephone line simulator connection. No board adjustments are required by the user,
although a (≈ 600Ω) line termination will need to be fitted to R20 before the EV6020 kit can be used.
Other, telco-specific, components may be added, as required.
BEFORE APPLYING POWER, PLEASE CHECK THE FOLLOWING:
When using the EV6020 board with the EV6000 µC board, it will be noted that each board has
connections for a single 8 - 35V dc power supply. Only one board needs to be connected as power is
supplied to the other board over the flat cable. Each board has its own power supply regulator chip,
with a jumper to select 3.3V or 5.0V (default ) operation.
MAKE SURE BOTH BOARDS HAVE THIS JUMPER SET TO THE SAME VOLTAGE. DAMAGE
MAY RESULT IF THIS STEP IS NOT OBSERVED. DO NOT OPERATE EITHER BOARD WITH
ITS VOLTAGE SELECTION JUMPER REMOVED.
Ensure the component value jumpers on the evaluation board are correctly set for 3.3V or 5.0V
operation. Please refer to Section 1.6.1.5 for further details.
1.3.2 Operation
This evaluation kit has no inherent functionality without a µC control board and appropriate firmware.
The evaluation board may be used independently of the µC board, if the user wishes to interface to a
different type of µC.
