Introduction

The ADC16DX370EVM is an evaluation board used to evaluate the ADC16DX370 analog-to-digital
converter (ADC) from TI. The ADC16DX370 device is a dual-channel, 16-bit ADC capable of operating at
sampling rates up to 370 Mega samples per second (MSPS). The ADC16DX370 device output data is
transmitted over a standard JESD204B high-speed serial interface.

This evaluation board also includes the following important features:

Transformer-coupled signal input network allowing a single-ended signal source from 5 MHz to 1 GHz

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

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

Device register programming via USB connector and FTDI USB-to-SPI bus translator

The digital data from the ADC16DX370EVM board can be quickly and easily captured with the
TSW14J56EVM data capture board. The TSW14J56EVM captures the high-speed serial data, decodes
the data, stores the data in memory, then uploads it to a connected PC through a USB interface for
analysis. The High Speed Data Converter Pro (HSDC Pro) software on the PC communicates with the
hardware and processes the data.

K&L Microwave is a trademark of K&L Microwave.
Rohde & Schwarz is a trademark of Rohde & Schwarz.
Trilithic is a trademark of Trilithic.
