Texas Instruments ADC3663EVM

Overview

ADC3663EVM from Texas Instruments is an evaluation module designed to characterize the ADC3663 - a dual-channel, 16-bit, 65 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 (65 MHz), and DCLKIN (260 MHz) for data capture synchronization. The EVM enables dynamic range and SNR validation in RF-sampling signal chain prototyping.

For engineers reviewing the ADC3663EVM datasheet, ADC3663EVM pinout, ADC3663EVM application, or ADC3663EVM equivalent, this page delivers verified hardware setup requirements, FPGA interface details with TSWDC155EVM, LVDS timing constraints, GUI configuration steps for ADC3663-specific modes, and real-world test conditions including 65 MHz clock + 5.135 MHz analog tone + 260 MHz DCLK alignment.

Technical Context

The ADC3663EVM interfaces directly with the TSWDC155EVM FPGA capture board via FMC connector, enabling real-time LVDS data streaming at 2-wire, 16-bit, DDC-bypass mode. It relies on external low-phase-noise signal generators locked to a common 10 MHz reference for CLK, analog input, and DCLKIN signals to ensure coherent sampling and accurate FFT-based performance analysis.

Power is supplied via 12 V DC jack with onboard regulation; configuration is performed over USB-C using the ADC36xxEVM LVDS GUI, which programs both the ADC3663 device registers and FPGA firmware. Default analog input routing uses CHAp (J7) and CHBp (J9) SMA connectors with integrated baluns for single-ended-to-differential conversion.

FAQ

What is the primary function of the ADC3663EVM?

The ADC3663EVM is an evaluation module built to assess the performance of the ADC3663 - a dual-channel, 16-bit, 65 MSPS analog-to-digital converter. It provides complete hardware and software infrastructure for measuring key metrics like SNR, SFDR, and ENOB under real-world conditions, including LVDS data capture, clock synchronization, and configurable analog input paths. The ADC3663EVM itself contains no active conversion circuitry but serves as a validated interface platform for the ADC3663 IC.

Which ADC devices does the ADC3663EVM support beyond the ADC3663?

In addition to the ADC3663, the ADC3663EVM supports evaluation of five other members of the same family: ADC3662 (2-channel, 16-bit, 25 MSPS), ADC3661 (2-channel, 16-bit, 10 MSPS), ADC3563 (1-channel, 16-bit, 65 MSPS), ADC3562 (1-channel, 16-bit, 25 MSPS), and ADC3561 (1-channel, 16-bit, 10 MSPS). All share identical pinout, power, and interface requirements, allowing reuse of the same ADC3663EVM hardware across variants.

How is the ADC3663EVM powered and what are its voltage requirements?

The ADC3663EVM is powered exclusively through a 12 V DC input via the barrel jack (J10); no onboard battery or alternative supply options exist. Internal LDOs generate all required rail voltages for the ADC3663, FPGA interface logic, and balun bias networks. The 12 V supply must deliver ≥1 A continuous current, and TI specifies strict low-noise performance for optimal ADC dynamic range measurement - ripple must remain below 10 mV_PP across 10 Hz–10 MHz.

What software tools are required to operate the ADC3663EVM?

Three software tools are mandatory: the ADC36xxEVM LVDS GUI (for device configuration and FPGA programming), Texas Instruments HSDC Pro (for FFT analysis and real-time data visualization), and AMD Vivado Lab Solutions (to compile and load FPGA bitstreams). All require Windows 10/11; Vivado Lab bin path must be added to the system PATH environment variable before launching the GUI. FX3 USB drivers are installed automatically during GUI setup.

Can the ADC3663EVM be used without the TSWDC155EVM data capture board?

No - the ADC3663EVM lacks onboard data capture or storage capability and cannot operate standalone. It requires connection to the TSWDC155EVM via the FMC-LPC connector (J1) to route LVDS data streams into an FPGA for buffering, formatting, and USB transmission to the host PC. The TSWDC155EVM provides the essential high-speed serial interface, memory buffer, and USB 3.0 bridge that the ADC3663EVM depends on for functional evaluation.
