Texas Instruments ADS5404EVM

Overview

ADS5404EVM from Texas Instruments is an evaluation module designed to characterize the ADS5404, a dual-channel, 12-bit analog-to-digital converter (ADC) operating at up to 800 MSPS with LVDS DDR digital outputs. It supports transformer-coupled differential analog inputs, single-ended clock input via SMA, and 5-V banana jack power supply. The EVM enables high-fidelity ADC performance validation including SNR, SFDR, and FFT analysis when paired with TSW1400/TSW1405 capture cards.

For engineers reviewing the ADS5404EVM datasheet, ADS5404EVM pinout, ADS5404EVM application, or ADS5404EVM equivalent, this page delivers verified technical context, key specifications, availability support, manufacturer background, and targeted FAQs - all grounded in TI's SLAU450 User's Guide and official EVM documentation.

Technical Context

The ADS5404EVM implements a dual-channel signal path with independent SMA analog inputs (J4, J5), each transformer-coupled to deliver balanced differential signals to the ADS5404. Clock input (J1) is single-ended SMA, internally converted to differential for ADC sampling. Power is supplied as a single 5-V rail via banana jacks (J7), with onboard TPS79601 LDOs generating 1.8 V (analog/digital domains) and 3.3 V (LVDS buffer, analog bias).

Control is implemented via USB-hosted SPI GUI software that configures ADS5404 registers, manages reset (SW1), and selects trigger sources (SMA J9, Samtec J11, or pushbutton SW2). High-speed data output uses a Samtec connector (J11) carrying two 12-bit LVDS DDR busses synchronized to a common clock, compatible with TSW1400/TSW1405 capture hardware.

FAQ

What is the primary function of the ADS5404EVM?

The ADS5404EVM is a dedicated evaluation module for the ADS5404 dual-channel, 12-bit, 800-MSPS ADC. It provides a complete signal chain - from transformer-coupled analog inputs and clock conditioning to LVDS DDR data output - enabling engineers to validate real-world ADC performance metrics such as SNR, SFDR, and spectral purity. The ADS5404EVM itself contains no ADC silicon; it hosts and interfaces with the ADS5404 device for functional and parametric testing.

Which capture cards are compatible with the ADS5404EVM?

The ADS5404EVM is explicitly designed for interoperability with Texas Instruments' TSW1400 and TSW1405 high-speed data capture cards. Connection is made via the Samtec connector (J11) on the ADS5404EVM and J3 on the capture card. This interface carries LVDS DDR data, clock, and optional trigger signals, and is validated in TI's SLAU450 User's Guide for seamless integration with High Speed Data Converter Pro software.

Does the ADS5404EVM include the ADS5404 ADC IC?

No - the ADS5404EVM is a bare evaluation board and does not include the ADS5404 ADC IC. Users must separately procure and mount the ADS5404 device onto the EVM's designated footprint. The board provides all necessary power regulation (TPS79601 LDOs), signal conditioning, clock distribution, and LVDS interfacing circuitry to operate the ADS5404 under controlled lab conditions.

How is the ADS5404EVM powered, and what voltage rails does it generate?

The ADS5404EVM accepts a single 5-V DC input via banana jacks (J7). From this, it generates three regulated voltage rails using TPS79601 LDOs: 1.8 V for both analog and digital domains of the ADS5404, and 3.3 V for the LVDS output buffer and analog bias circuits. Jumpers JP12–JP15 configure rail routing, and LED D1 confirms presence of 5-V input power.

Can the ADS5404EVM be used without a TSW140x capture card?

Yes - the ADS5404EVM can operate standalone for basic register configuration and analog signal evaluation using its USB SPI GUI, but full high-speed data capture and FFT analysis require external hardware. Without a TSW1400/TSW1405, users cannot stream or process the 800-MSPS LVDS DDR output. The ADS5404EVM's Samtec J11 interface is purpose-built for TSW140x compatibility; alternative capture solutions would require custom FPGA-based receivers and timing alignment logic.
