ADS42JBx9 System Evaluation Kit
This document outlines the basic steps and functions that are required to ensure the proper operation of
the ADS42JBx9 System Evaluation Kit (SEK). The kit includes an ADS42JBx9EVM, a JESD204B
Translation Card, two 5-VDC power supplies, and a mini-USB cable. This kit is designed for use with the
Texas Instruments (TI) TSW1400 High Speed Data Capture/Pattern Generator Card (not included)
running with the High Speed Data Converter Pro GUI software. The ADS42JBx9EVM contains either an
ADS42JB49 (14-bit) or ADS42JB69 (16-bit) dual-channel, 250-MSPS, analog-to-digital converter. The
EVM also contains a TI LMK04828 clock jitter cleaner. The TI JESD204B Translation card receives
JESD204B standard output data from the ADC EVM and translates it to parallel LVDS data that can be
captured by the TSW1400 for analysis. This guide helps users to quickly evaluate the performance of the
ADS42JBx9EVM boards by capturing and displaying waveforms using the TSW1400. The EVM
schematics, BOMs, and layout files are found in the design package under the ADS42JBx9SEK product
folder on www.ti.com.
