Texas Instruments ADS4229EVM

Overview

ADS4229EVM from Texas Instruments is an evaluation module designed to demonstrate and validate the ADS4229 dual-channel, 12-bit, 250-MSPS analog-to-digital converter. It supports DDR LVDS and parallel CMOS output configurations, integrates on-board THS4509 input op-amps and CDCE72010 clock synthesizer options, and interfaces directly with the TSW1400 high-speed data capture card for real-time waveform analysis.

For engineers reviewing the ADS4229EVM datasheet, ADS4229EVM pinout, ADS4229EVM application, or ADS4229EVM equivalent, this page provides verified hardware configuration details, jumper-controlled interface modes (SPI/parallel), clock/data output routing options, and validated test procedures using TI's HSDC Pro software and TSW1400 platform.

Technical Context

The ADS4229EVM implements a complete signal chain for the ADS4229 ADC, including transformer-coupled or THS4509-driven analog inputs, selectable 160–250 MHz clock paths via onboard CDCE72010 or external source, and configurable digital outputs (DDR LVDS or 1.8-V parallel CMOS). Jumper settings define serial SPI control (default) or pin-based parallel control, while power sequencing and LDO regulation are managed through JP15–JP19 and JP28–JP29.

It enables full register-level control of the ADS4229 via USB-connected GUI, supporting gain adjustment per channel, SNRBoost enable/disable, offset correction, LVDS/CMOS output format selection, high-frequency mode, and low-speed mode - all validated against SBAS533 datasheet behavior and confirmed in SLAU333A Rev B user guide test procedures.

FAQ

What is the primary function of the ADS4229EVM?

The ADS4229EVM is an evaluation module built to demonstrate and verify the performance of the ADS4229 dual-channel, 12-bit, 250-MSPS analog-to-digital converter. It provides configurable analog input paths (transformer or THS4509 op-amp), clock synthesis options (CDCE72010 or external), and digital output formats (DDR LVDS or parallel CMOS), all validated in TI's SLAU333A user guide. The ADS4229EVM enables rapid system-level testing when paired with the TSW1400 capture card and HSDC Pro software.

Which ADC does the ADS4229EVM support?

The ADS4229EVM is specifically designed for the ADS4229 - a dual-channel, 12-bit, 250-MSPS analog-to-digital converter from Texas Instruments. While the board shares mechanical and firmware compatibility with other ADS42xx family members (e.g., ADS4225, ADS4249), its default jumper settings, layout optimizations, and test procedures in SLAU333A Rev B are explicitly validated for ADS4229 operation under 250-MSPS sampling conditions.

How do I configure the ADS4229EVM for parallel CMOS output?

To configure the ADS4229EVM for parallel CMOS output, install SN74AVC16T245 buffers U12 and U13, remove RN5–RN12, and shunt JP26 and JP27. This routes 1.8-V CMOS data from the ADS4229 to 40-pin connectors J1 (Channel A) and J2 (Channel B), as documented in Table 5 of SLAU333A. DDR LVDS remains active only when U12/U13 are uninstalled and RN5–RN12 are populated - confirming mutually exclusive output mode selection on the ADS4229EVM.

Does the ADS4229EVM include on-board clock generation?

Yes, the ADS4229EVM supports optional on-board clock generation using the CDCE72010 clock synthesizer. With a 10-MHz reference at J19 and either a 983.04-MHz or 491.52-MHz VCXO, the CDCE72010 outputs 245.76 MHz or 122.88 MHz LVCMOS clock signals at U0P (pin 7), filtered through on-board crystal BPF Y0 before feeding the ADS4229. This configuration replaces the default transformer-coupled clock path and is enabled by modifying jumpers J14, SJP6, SJP7, R121/R122 per Table 4 in SLAU333A.

What software is required to operate the ADS4229EVM?

The ADS4229EVM requires the ADS58C28_ADS42xx_GUI_vxpx software for register-level control and the High Speed Data Converter Pro (HSDC Pro) GUI bundled with the TSW1400 EVM for data capture and FFT analysis. The ADS4229EVM GUI supports Top Level and Advanced register tabs, SPI communication over USB, and *.ini file integration for device-specific initialization - all verified in SLAU333A Section 1 and TSW1400 documentation. USB drivers are installed automatically during setup or manually from C:\Program Files\Texas Instruments\ADS58C28_ADS42xx\data\.
