Overview
This document is intended to serve as a user’s guide for the ADS5XJ6x EVM. The ADS5XJ6XEVM is an
evaluation module (EVM) designed to evaluate the ADS58J63 and ADS54J66 high-speed, JESD204B
interface ADCs. The EVM includes an onboard clocking solution (LMK04828), transformer coupled inputs,
full power solution, and easy-to-use software GUI and USB interface.
The following features apply to this EVM:
•
Transformer-coupled signal input network allowing a single-ended signal source from 0.25 MHz to 750
MHz
•
LMK04828 system clock generator that generates FPGA reference clocks for the high-speed serial
interface and may be used to generate the ADC sampling clock (default setting)
•
Transformer-coupled clock input network to test the ADC performance with a very low-noise clock
source
•
High-speed serial data output over a standard FMC interface connector
The ADS5XJ6XEVM is designed to work seamlessly with the TSW14J56EVM, Texas Instruments’
JESD204B data capture/ pattern generator card, through the High Speed Data Converter Pro (HSDC Pro)
software tool for high-speed data converter evaluation. The ADS5XJ6XEVM was also designed to work
with many of the development kits from leading FPGA vendors that contain an FMC connector.
