Texas Instruments ADS58C48EVM

Overview

ADS58C48EVM from Texas Instruments is an evaluation module for the ADS58C48 quad 11-bit, 200 MSPS analog-to-digital converter with per-channel SNRBoost capability and LVDS/CMOS output flexibility. It enables full register-level configuration via USB-connected GUI software and supports transformer-coupled or PGA870-based OPA-driven input paths for Channel D.

For engineers reviewing the ADS58C48EVM datasheet, ADS58C48EVM pinout, ADS58C48EVM application, or ADS58C48EVM equivalent, this EVM provides validated test setup guidance, jumper-configurable signal paths, real-time FFT performance validation at 200 MSPS, and register-level control of gain, data format, power-down, and SNRBoost filter selection across all four channels.

Technical Context

The ADS58C48EVM implements a complete signal chain interface for the ADS58C48 ADC, including on-board clock conditioning, four independent analog input paths (J4–J9), configurable power rails (AVdd, DRVdd, 3.3 V, 6 V), and USB-based register access via TI's ADS58C48_GUI_vxpx software. It integrates hardware jumpers (JP4–JP19, SJP1–SJP4) to select supply sources, enable/disable SNRBoost per channel pair, and configure PGA870 operation.

Test integration is standardized through TSW1200 capture card compatibility, supporting LVDS DDR data input and single-tone FFT analysis. Performance validation includes coherent sampling at 200 MHz clock with 149 MHz input tone, with documented SNR and SFDR results both with and without SNRBoost enabled using Filter #40 (BW ≈ 60 MHz).

FAQ

What is the primary function of the ADS58C48EVM?

The ADS58C48EVM is an evaluation module for the ADS58C48 quad 11-bit, 200 MSPS ADC. It provides a fully assembled, tested platform with USB-controlled register access, configurable analog inputs, and TSW1200-compatible data capture-enabling immediate performance validation and system integration testing without custom PCB design. The ADS58C48EVM supports both transformer-coupled and PGA870-based input configurations.

Does the ADS58C48EVM support SNRBoost functionality, and how is it configured?

Yes, the ADS58C48EVM supports per-channel SNRBoost via hardware jumpers (JP11, JP13) and software register control in the ADS58C48_GUI_vxpx. Users can enable SNRBoost independently for Channel A/B or C/D pairs and select filter types-including Filter #40 (≈60 MHz bandwidth at 200 MSPS)-to improve in-band SNR. Both hardware and software enablement paths are documented in the SLAU313 user's guide for the ADS58C48EVM.

Which software tools are required to operate the ADS58C48EVM?

The ADS58C48EVM requires TI's ADS58C48_GUI_vxpx software for register-level control and the TSW1200 GUI for data capture and FFT analysis. The ADS58C48_GUI_vxpx installs USB drivers and provides Top Level (switch-based) and Advanced (address/data entry) register interfaces. The TSW1200 software must be configured with the correct ini file and jumper settings to recognize the ADS58C48EVM as a valid ADC source.

Can the ADS58C48EVM be used with DC-coupled analog inputs?

Yes-the ADS58C48EVM supports DC-coupled operation on Channel D (J9) via optional PGA870 configuration. By repositioning jumpers SJP1–SJP4 and JP16–JP19 per Table 2 in SLAU313, users can route the input through the programmable-gain op-amp instead of the default transformer-coupled path. This enables adjustable gain, DC offset control, and low-frequency signal digitization not possible with AC-coupled transformers alone.

What power supply requirements does the ADS58C48EVM have?

The ADS58C48EVM requires a 6 V DC supply (via banana jacks J1/J3) for analog and digital core rails, with jumper-selectable distribution to AVdd (JP4), DRVdd (JP5), and auxiliary 3.3 V (JP8). USB 5 V (JP6) powers the interface logic. Total supply current is ~470 mA ±20 mA when all four channels operate at 200 MSPS with SNRBoost enabled-verified in Section 2.5 of the ADS58C48EVM user's guide.
