Texas Instruments ADS54T02EVM

Overview

ADS54T02EVM from Texas Instruments is an evaluation module designed to characterize the ADS54T02, a dual-channel, 12-bit analog-to-digital converter (ADC) operating at up to 800 MSPS with LVDS DDR digital output. It supports transformer-coupled differential analog inputs, single-ended clock input via SMA, and trigger-based burst capture for high-resolution data acquisition in RF and communications test systems.

For engineers reviewing the ADS54T02EVM datasheet, ADS54T02EVM pinout, ADS54T02EVM application, or ADS54T02EVM equivalent, this page delivers verified technical context, key specifications, supply support, manufacturer background, and targeted FAQs - all grounded in TI's SLAU450 User's Guide and official EVM documentation.

Technical Context

The ADS54T02EVM provides full hardware interface and signal conditioning for the ADS54T02 ADC, including dual-channel 50-Ω SMA analog inputs with transformer coupling, a single-ended 50-Ω clock input with on-board differential conversion, and configurable trigger routing via SMA J9, Samtec J11, or pushbutton SW2. Power is supplied via 5-V banana jacks, with onboard TPS79601 LDOs generating 3.3 V and 1.8 V rails for analog/digital domains.

Control is implemented through USB-hosted SPI GUI software, enabling register-level configuration of HP Mode 1, offset correction, burst length, and sync functions. The EVM mates directly with TI's TSW1400/TSW1405 capture cards via Samtec J11 for FFT-based performance analysis including SNR, SFDR, and spectral purity metrics.

FAQ

What is the primary function of the ADS54T02EVM?

The ADS54T02EVM is a dedicated evaluation module for the ADS54T02 dual-channel, 12-bit, 800 MSPS ADC. It provides complete signal conditioning, power regulation, trigger routing, and USB-based SPI control to enable accurate characterization of dynamic performance metrics such as SNR, SFDR, and ENOB - all documented in TI's SLAU450 User's Guide. The ADS54T02EVM itself is not an IC but a test platform built around the ADS54T02 device.

Which capture cards are compatible with the ADS54T02EVM?

The ADS54T02EVM is explicitly designed to interface with Texas Instruments' TSW1400 and TSW1405 high-speed data capture cards via its Samtec J11 connector. This integration enables seamless data transfer, burst-triggered acquisition, and real-time FFT analysis using TI's High Speed Data Converter Pro software. No third-party or generic capture hardware is validated or supported per the SLAU450 documentation for the ADS54T02EVM.

How is clocking implemented on the ADS54T02EVM?

The ADS54T02EVM accepts a single-ended clock signal via SMA connector J1, which feeds into an on-board transformer to generate the differential clock required by the ADS54T02 ADC. This design ensures proper common-mode rejection and timing integrity at sampling rates up to 800 MSPS. External clock sources must be 50-Ω terminated and meet jitter and slew-rate requirements specified in the ADS54T02 datasheet - not derived from the ADS54T02EVM itself.

Does the ADS54T02EVM support both single-ended and differential analog inputs?

The ADS54T02EVM supports transformer-coupled differential analog inputs by default via SMA connectors J4 (Channel A) and J5 (Channel B). Surface-mount jumpers (L1–L4, R20–R42) allow optional reconfiguration for single-ended input paths, but doing so bypasses the input transformers and degrades phase/amplitude balance - a trade-off explicitly noted in the SLAU450 User's Guide. The ADS54T02EVM does not include active baluns or DC-coupled input options.

What software is required to operate the ADS54T02EVM?

Operation of the ADS54T02EVM requires TI's ADS540x_GUI_v1.3 software for USB-based SPI register control and TI's High Speed Data Converter Pro software (with ADS5402.ini initialization file) for data capture and FFT analysis when used with the TSW1400/TSW1405. Both tools are referenced in SLAU450 and must be installed separately - no standalone firmware or embedded OS resides on the ADS54T02EVM hardware itself.
