Texas Instruments ADS5407EVM

Overview

ADS5407EVM from Texas Instruments is an evaluation module designed to characterize the ADS5407 - 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, 5-V single-rail power supply, and SPI-based register configuration via USB interface. The EVM enables high-fidelity signal acquisition for RF receiver, communications test, and wideband instrumentation applications.

For engineers reviewing the ADS5407EVM datasheet, ADS5407EVM pinout, ADS5407EVM application, or ADS5407EVM equivalent, this page provides verified technical context, key specifications, availability support, manufacturer background, and practical FAQs - all grounded in TI's official SLAU450 User's Guide and EVM hardware documentation.

Technical Context

The ADS5407EVM implements a complete signal chain for evaluating the ADS5407 ADC, including dual SMA analog input paths with transformer coupling for balanced differential drive, a single-ended clock input converted to differential via transformer, and on-board LDO regulation generating 1.8 V (analog/digital) and 3.3 V (analog/LVDS buffer) rails from a 5-V banana jack supply. All voltage domains are jumper-configurable for independent biasing.

Control is delivered through a USB-connected SPI GUI that programs the ADS5407 register map, supports reset assertion, HP Mode 1 enablement, channel offset correction, and burst-length configuration for ADS54T0x variants. Trigger routing options include SMA J9, pushbutton SW2, or Samtec connector J11 for synchronization with TSW1400/TSW1405 capture cards.

FAQ

What is the primary function of the ADS5407EVM?

The ADS5407EVM is a dedicated evaluation module for the ADS5407 dual-channel, 12-bit, 800-MSPS ADC. It provides a complete hardware and software environment-including analog input conditioning, clock interface, power regulation, LVDS data output, and USB-based SPI control-to validate ADC performance metrics such as SNR, SFDR, and spurious response under real-world signal conditions. ADS5407EVM enables rapid characterization without custom PCB development.

Which ADC does the ADS5407EVM support, and is it compatible with other ADS540x devices?

The ADS5407EVM is explicitly designed for the ADS5407 but shares mechanical and electrical compatibility with the broader ADS540x and ADS54T0x families, including ADS5402 and ADS54T02, as confirmed in TI's SLAU450 User's Guide. Pin-compatible layout, shared register map structure, and identical LVDS output format allow the same EVM to evaluate multiple members of the family-though specific features like burst mode require device-specific register settings in ADS5407EVM software.

How is the ADS5407EVM powered, and what voltage rails does it generate?

The ADS5407EVM accepts a single 5-V DC input via banana jacks (J7), then uses onboard TPS79601 LDO regulators to derive three critical voltage rails: 1.8 V for analog and digital supplies (AVDD/DVDD), 3.3 V for analog AVDD3P3, and a separate 3.3-V rail for the LVDS trigger buffer. Jumpers JP12–JP15 allow independent connection or isolation of each rail, supporting flexible power domain testing per the ADS5407 datasheet requirements.

Can the ADS5407EVM be used with the TSW1405 capture card, and what is required for integration?

Yes - the ADS5407EVM is fully interoperable with the TSW1405 capture card. Integration requires connecting Samtec connector J11 on the ADS5407EVM to J3 on the TSW1405, supplying 5 V to both units, providing a clean clock signal to J1, and routing analog input to J4 or J5. Software coordination uses TI's High Speed Data Converter Pro GUI with ADS5402.ini initialization file loaded, enabling FFT analysis, SNR calculation, and real-time waveform visualization directly from ADS5407EVM output data.

Does the ADS5407EVM include on-board signal conditioning, and how is analog input configured?

Yes - the ADS5407EVM includes dual transformer-coupled input paths (one per channel) for optimal amplitude and phase balance, plus solder-selectable bypass options (L1/L2/L3/L4, R20/R23, etc.) to route signals directly to the ADC without transformers. Each channel supports AC-coupled differential input by default, with optional VCM biasing via zero-ohm resistors (R5/R6). This architecture allows precise evaluation of ADS5407's dynamic performance across both standard and custom front-end configurations.
