Texas Instruments ADC3662EVM

Overview

ADC3662EVM from Texas Instruments is an evaluation module designed to characterize the ADC3662 - a dual-channel, 16-bit, 25 MSPS high-speed analog-to-digital converter with LVDS serial output and internal decimation filtering. It supports AC-coupled single-ended or differential analog inputs via onboard balun, external sampling clock input (up to 65 MHz), and DCLKIN for FPGA capture synchronization. The EVM enables dynamic range validation in software-defined radio and spectrum analysis applications.

For engineers reviewing the ADC3662EVM datasheet, ADC3662EVM pinout, ADC3662EVM application, or ADC3662EVM equivalent, this page provides verified hardware configuration details, supported TI data capture tools (TSWDC155EVM), HSDC Pro GUI integration, LVDS interface setup, and ADC3662-specific sample rate and resolution calibration workflows.

Technical Context

The ADC3662EVM implements a modular hardware architecture centered on the ADC3662 IC, interfacing via FMC connector to the TSWDC155EVM FPGA capture board. It uses external 12 V power with onboard regulation and supports flexible clocking through SMA connectors for CLKn and DCLKIN, with precise frequency requirements (e.g., 65 MHz sampling clock, 260 MHz DCLK for 16-bit 2-wire bypass mode).

Configuration is managed over USB-C using the ADC36xxEVM LVDS GUI, which programs both the ADC3662 device registers and FPGA firmware. The EVM supports oversampling + decimation modes and allows analog input routing through transformer-coupled single-ended or differential paths, preserving signal integrity for ENOB and SFDR validation.

FAQ

What is the ADC3662EVM used for?

The ADC3662EVM is used to evaluate the ADC3662 - a dual-channel, 16-bit, 25 MSPS analog-to-digital converter - under real-world conditions including LVDS data capture, clock jitter sensitivity, SNR/ENOB validation, and decimation filter performance. It enables engineers to verify ADC3662 behavior before integrating it into final systems such as spectrum analyzers or SDR front-ends.

Which ADC devices does the ADC3662EVM support?

The ADC3662EVM is specifically configured to evaluate the ADC3662, but shares hardware compatibility with other members of the ADC366x family including ADC3663 and ADC3664. Configuration in the ADC36xxEVM GUI must be set to "ADC3662" to load correct register maps, timing constraints, and resolution settings for the ADC3662 device.

What software is required to operate the ADC3662EVM?

To operate the ADC3662EVM, users require three software components: the ADC36xxEVM LVDS GUI (for device configuration), Texas Instruments HSDC Pro (for FFT and performance visualization), and AMD Vivado Lab Solutions (for FPGA bitstream loading and data capture). All are mandatory; omission of any prevents full functionality of the ADC3662EVM.

How is the ADC3662EVM powered and connected?

The ADC3662EVM is powered by an external 12 V DC supply via its barrel jack (J1), with onboard regulation delivering clean rails to the ADC3662 and supporting circuitry. It connects to a host PC via USB-C (J3) for control and to the TSWDC155EVM via FMC (J1) for high-speed LVDS data capture - no standalone operation is possible without both connections.

Does the ADC3662EVM include analog input transformers?

Yes, the ADC3662EVM includes onboard baluns that provide passive single-ended-to-differential conversion for analog inputs, supporting both CHA and CHB channels. These transformers enable low-noise, low-distortion AC-coupled signal injection - critical for accurate ENOB and SFDR measurements of the ADC3662 during evaluation.
