Overview
1 Overview
The DAC90xEVM is an evaluation module (EVM) designed to evaluate the DAC90x. The EVM provides
simple and minimal external components to minimize system cost and power consumption. The
DAC90xEVM is designed to work seamlessly with the TSW1400EVM, data capture and pattern generator
module. The TSW1400EVM is programed through TI's High-Speed Data Converter Pro Graphic User
Interface (HSDC Pro GUI) software tool for high-speed data converter evaluation.

Quick-Start Guide
2 Quick-Start Guide
This section guides the user through the EVM test procedure to obtain a valid data capture from the
DAC90xEVM using the TSW1400EVM 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 DAC90xEVM and TSW1400EVM to the
computer for the first time.
2.1.1 High-Speed Data Converter Pro GUI Installation
The High-Speed Data Converter Pro (HSDC Pro) is used to control the TSW1400EVM and analyze the
captured data. See High Speed Data Converter Pro GUI for more information.
1. Download HSDC Pro from the TI website. The References section of this document contains the link 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.

2.2 Hardware Setup Procedure
A typical test setup using the DAC90xEVM and TSW1400EVM is shown in Figure 3. This is the test setup
used for the quick-start procedure. The rest of this section describes the hardware setup steps.
Quick-Start Guide
2.2.1 TSW1400EVM Setup
Figure 3. Quick-Start Test Setup
Set up the TSW1400EVM with the following steps:
1. Connect the DAC90xEVM to the TSW1400EVM by connecting pin 1 of the CMOS_INTERFACE (J1) to
pin 1 of the DAC90xEVM output data (J1).
2. Connect the power cable to connector J12 (+5 V IN) to the TSW1400EVM.
3. Connect the mini-USB cable to the USB connector (J5).
4. Turn on the power supply. Flip the power switch (SW7) to the ON position. The board should draw
around 0.5 A after power up. This will increase to around 1.7 A when loaded with firmware.
