ADS54J20EVM

Quick Start Guide

This section guides the user through the EVM test procedure to obtain a valid data capture from the
ADS54J20EVM using the TSW14J56EVM capture card. This should be the starting point for all
evaluations.

2.1

Software Installation

The proper software must be installed before beginning evaluation. See

Section 1.2

for a list of the

required software. The

References

section of this document contains links to find the software on the TI

website.

Important:

The software must be installed before connecting the ADS54J20EVM and TSW14J56 to the

computer for the first time.

2.1.1

ADS54Jxx EVM GUI Installation

The ADS54Jxx EVM GUI is used to control the ADS54J20EVM. It must be used to properly configure the
devices on the EVM.

1. Download the ADS54Jxx EVM GUI from the TI website. The

section of this document

contains links to find the software on the TI website.

2. Extract the files from the zip file.

3. Run

setup.exe

and follow the installation prompts.

2.1.2

High Speed Data Converter Pro GUI Installation

High Speed Data Converter Pro (HSDC Pro) is used to control the TSW14J56EVM and analyze the
captured data. Please see the HSDC Pro user’s guide (

SLWU087

) for more information.

1. Download HSDC Pro from the TI website. The
