Texas Instruments ADS58C28EVM

Overview

ADS58C28EVM from Texas Instruments is an evaluation module designed to accelerate development and characterization of the ADS58C28 dual-channel, 11-bit, 200 MSPS analog-to-digital converter. It provides full register-level software control via USB interface, supports LVDS and CMOS output configurations, and integrates jumper-selectable signal paths for clock, analog input (transformer or THS4509 op-amp), and data output modes.

For engineers reviewing the ADS58C28EVM datasheet, ADS58C28EVM pinout, ADS58C28EVM application, or ADS58C28EVM equivalent, this module enables rapid validation of high-speed ADC performance-including SNRBoost-enabled FFT analysis at 200 MSPS sampling with coherent tone inputs up to 140 MHz-when paired with the TSW1200 capture card.

Technical Context

The ADS58C28EVM implements a complete hardware test platform for the ADS58C28 ADC, featuring configurable analog front-end options (transformer-coupled or THS4509-driven), on-board CDC72010 clock driver support, and selectable DDR LVDS or parallel CMOS digital outputs. It includes dedicated jumpers for SPI/parallel control mode, power-down management, and SNRBoost hardware enable/disable via JP5–JP7.

Software interaction is enabled through the ADS58C28_ADS42xx_GUI, offering Top Level and Advanced register tabs for real-time configuration of gain, data format (2's complement), LVDS/CMOS output strength, SNRBoost filter selection (e.g., Filter #40 for ~60 MHz BW), and channel-specific high-frequency/low-speed modes-all synchronized with TSW1200 FFT-based performance measurement.

FAQ

What is the primary function of the ADS58C28EVM?

The ADS58C28EVM is an evaluation module built to demonstrate and validate the operation of the ADS58C28 dual-channel, 11-bit, 200 MSPS analog-to-digital converter. It provides hardware interfaces, jumper-configurable signal paths, and USB-based GUI software to configure registers, capture waveforms, and analyze performance metrics like SNR and SFDR - all centered around the ADS58C28 device itself.

How does the ADS58C28EVM interface with the TSW1200 capture card?

The ADS58C28EVM connects directly to the TSW1200 EVM via board-to-board headers, enabling high-speed LVDS DDR data transfer. The TSW1200 handles data capture, FFT analysis, and display, while the ADS58C28EVM supplies properly conditioned ADC output. Jumper settings on both boards (e.g., J10/J11 on TSW1200 and JP20/JP21 on ADS58C28EVM) must be configured for LVDS DDR mode to ensure synchronization and error-free acquisition.

Can the ADS58C28EVM operate without the TSW1200?

No - the ADS58C28EVM lacks onboard memory, data storage, or display capability. Its core purpose is to condition and output digitized data from the ADS58C28 ADC; it relies on external equipment like the TSW1200 for capture, visualization, and quantitative analysis. The included GUI controls only register configuration and does not perform waveform capture independently.

What analog input configurations does the ADS58C28EVM support?

The ADS58C28EVM supports two analog input topologies: default transformer-coupled differential input (via T1–T4) and optional THS4509 op-amp–driven single-ended-to-differential conversion. Configuration requires physical component and jumper changes per Table 3 in the SLAU329 user's guide - including resistor placement (e.g., R120/R129) and shunt selection (SJP3/SJP4) - with no shared components between modes.

Does the ADS58C28EVM include on-board clock generation?

Yes - the ADS58C28EVM supports optional on-board clock synthesis using the CDC72010 clock driver. With a 10 MHz reference and onboard 983.04 MHz or 491.52 MHz VCXO, it generates precise LVCMOS clock outputs (e.g., 245.76 MHz or 122.88 MHz) routed through an on-board crystal BPF to the ADS58C28's CLK input. Default operation uses transformer-coupled external clock injection at J19.
