Test Set-up Connection
1. Connect the J5 connector of the EVM to the J3 connector of TSW1400 EVM
2. Connect 5 V to the J12 supply input connector of the TSW1400 and 6 V to the J1 supply input
connector of the EVM
3. Provide a sample clock at J10 SMA connector of the EVM
4. Provide a sine wave for the analog input at J6, J8, J11, or J13 SMA connectors of the EVM
5. Connect a USB cable from the TSW1400 to the programming computer
6. Connect a USB cable from the EVM to the computer
7. Ensure the initial jumper settings of ADS58H40, as per
desired)

ADS58H40 Software Quick Start Guide
Figure 6
introduced the front panel of the ADS58H40 SPI GUI. This section covers the initial use of the
SPI GUI necessary for most evaluations of the ADS58H40.
1. Press the Reset USB Port button if the USB connection has been disrupted since last use, or if an
error message pops up warning that the USB connection is not valid.
2. Use the mouse to select the reset position of the reset switch. This switch is self-clearing.
3. Press Send All to send all the register settings.
4. From this point, select digital functions as desired such as SNRBoost, or set test pattern modes if
desired. All register bits listed in the register map of the ADS58H40 data sheet have a switch on the
front panel of the SPI GUI for easy configuration of the ADS58H40.
Note that any greyed-out front panel switches are unavailable for use because they have a dependency
upon other switch settings, as indicated in the ADS58H40 datasheet. For example, the Channel A Gain
selection is unavailable because the default state of the Channel A Gain Enable switch is off. Select the
Channel A Gain Enable switch, toggling the switch to the enabled state, and then the Channel A Gain
selection becomes available for use.

ADS58H40 and TSW1400 Setup Guide
Reference the TSW1400 User's Guide (SLWU079A) for more detailed explanations of the TSW1400 set-
up and operation. This document assumes the High Speed Data Converter Pro software and the
TSW1400 hardware are installed and functioning properly. This EVM requires High Speed Data Converter
Pro software version 1.2 with TSW1400 hardware of Rev D (or higher).
Single-tone FFT test (ADS58H40 11-bit Operating Mode)
1. Start the High Speed Converter Pro GUI program. When the program starts, select the ADC tab and
then select either the ADS58H40-11b or the ADS58H40-14b device in the Select ADC menu. For this
example, select the ADS58H40-11b device.
(a) For 11-bit Operating Mode or 11-bit SNRBoost Mode, select the ADS58H40-11b device.
(b) For 14-bit High Resolution Burst Mode, select the ADS58H40-14b device.
