Texas Instruments ADS5292EVM

Overview

ADS5292EVM from Texas Instruments is an evaluation module designed to characterize the ADS5292 8-channel, 12-bit analog-to-digital converter (ADC) under real-world signal, clock, reference, and power supply conditions. It supports onboard CMOS clocking at 80 MHz, LVDS 2-wire output interface, and configurable analog input paths for all eight channels via SMA connectors J6–J15 or alternative J16 for Channel 8.

For engineers reviewing the ADS5292EVM datasheet, ADS5292EVM pinout, ADS5292EVM application, or ADS5292EVM equivalent, this page provides verified technical context, key specifications, USB interface setup guidance, TSW1400EVM interoperability details, and hardware configuration options including jumper-selectable clock sources and power rail enablement.

Technical Context

The ADS5292EVM implements a complete signal chain for the ADS5292 ADC, featuring eight independent analog input paths with transformer-coupled (default) or amplifier-based (J16) configurations, onboard +3.3V/1.8V analog and +1.8V digital power regulation, and integrated CDCLVP1102 clock buffer for differential clock conditioning. It interfaces directly with the TSW1400EVM via P10 LVDS connector for high-speed data capture and analysis.

USB communication is handled by an FT245RL USB FIFO IC (U10), enabling PC-based control of ADC configuration registers, test pattern generation, and power management functions. The board supports five ADC clock source modes-including default onboard 80 MHz CMOS oscillator-and includes LED indicators for +5V, +3.3VA, +1.8VA, and +1.8VD rails.

FAQ

What is the primary function of the ADS5292EVM?

The ADS5292EVM is an evaluation module built to assess the performance of the ADS5292 8-channel, 12-bit, 80-MSPS analog-to-digital converter. It provides full hardware and software infrastructure-including onboard clock, regulated power rails, USB control interface, and LVDS data output-to validate dynamic parameters like SNR, SFDR, and ENOB across all channels under user-defined signal and timing conditions. The ADS5292EVM enables rapid prototyping and characterization without custom PCB design.

Which software tools are required to operate the ADS5292EVM?

Operation of the ADS5292EVM requires two TI-provided software components: the ADS5292 GUI for device register configuration, power management, and test pattern control; and the High Speed Data Converter Pro (HSDCPro) GUI-installed via the TSW1400EVM software package-for time-domain waveform visualization and single-tone FFT analysis. Both tools communicate with the ADS5292EVM through its FT245RL USB interface and require WHQL-certified drivers for Windows XP and later.

How does the ADS5292EVM connect to the TSW1400EVM?

The ADS5292EVM connects to the TSW1400EVM via a 40-pin P10 LVDS ribbon cable, which carries serialized 8-channel ADC data and synchronization signals. This link allows the TSW1400EVM to de-serialize and buffer the high-speed LVDS stream for real-time display and spectral analysis. Both boards also require separate USB connections to the host PC-one for ADS5292EVM control (USB1) and one for TSW1400EVM data streaming (J8).

What clock options does the ADS5292EVM support?

The ADS5292EVM supports five ADC clock configurations via jumper settings: (1) default onboard 80 MHz CMOS oscillator (JP13/JP19/JP20/JP16/JP18), (2) external single-ended CMOS clock via SMA J8, (3) transformer-coupled external clock via SMA J4, (4) buffered onboard clock using CDCLVP1102 (U4), and (5) buffered external CMOS clock. Each mode is validated in Table 3 of the SLAU377A User's Guide and requires specific jumper combinations to route clock signals correctly to the ADS5292IPFP.

Can the ADS5292EVM be used without the TSW1400EVM?

No-the ADS5292EVM lacks on-board data capture memory or direct PC streaming capability. Its LVDS output is designed exclusively for connection to the TSW1400EVM, which provides the LVDS deserializer, FPGA-based buffering, and USB 2.0 interface needed to transfer acquired samples to the host PC. While the ADS5292EVM GUI allows register access and basic test pattern generation, full signal analysis (e.g., FFT, histogram, spectral plots) requires the TSW1400EVM and HSDCPro software stack.
