Hardware Setup Procedure

A typical test setup using the ADC31JB68EVM and TSW14J56EVM is shown in

. This is the test

setup that will be used for the quick start procedure. The rest of this section describes the hardware setup
steps.

Figure 2. Quick Start Test Setup

2.2.1

TSW14J56EVM Setup

First, setup the TSW14J56EVM using the following steps:

1. Connect the ADC31JB68EVM to the TSW14J56EVM via the FMC connectors

2. Connect the included power cable for the TSW14J56EVM to the bench power supply

3. Test the voltage at the output of the power cable to verify correct polarity. The center core of the barrel

connector must have +5V relative to the outside ground shield.

4. Connect the power cable to connector J11 (+5V IN) of the TSW14J56EVM

5. Connect the included mini-USB cable to the USB connector (J9) of the TSW14J56EVM

6. Flip the power switch (SW6) of the TSW14J56EVM to the

ON
