Texas Instruments ADS5295EVM

Overview

ADS5295EVM from Texas Instruments is an evaluation module designed to characterize the ADS5295 8-channel, 65-MSPS analog-to-digital converter under real-world signal, clock, reference, and power supply conditions. It supports onboard 80-MHz CMOS clock generation, LVDS data output interface, and configurable analog/digital power rails (+3.3V, +1.8VA, +1.8VD). The module enables full register-level control via TSW1400EVM and High Speed Data Converter Pro GUI for time-domain and FFT-based performance validation.

For engineers reviewing the ADS5295EVM datasheet, ADS5295EVM pinout, ADS5295EVM application, or ADS5295EVM equivalent, this page delivers verified hardware configuration details, test setup requirements (including mandatory TSW1400EVM interconnection), jumper-controlled clock modes, and ADC channel-specific input routing - all essential for rapid ADC evaluation and system integration planning.

Technical Context

The ADS5295EVM interfaces directly with the ADS5295 ADC (8-channel, 65 MSPS, 12-bit) and requires the TSW1400EVM for LVDS deserialization and PC-based capture. It implements five selectable ADC clock sources: onboard 80-MHz CMOS oscillator (default), external single-ended CMOS, transformer-coupled differential, buffered onboard clock (CDCLVP1102), or buffered external CMOS input.

Power delivery includes on-board LDOs generating +3.3V analog, +1.8V analog, and +1.8V digital rails from a single +5-V input (1.5-A capable supply). Input conditioning supports eight SMA-connected analog channels, with Channel 8 offering dual-path configuration (transformer-coupled default or THS4509 amplifier-based alternative).

FAQ

What is the required companion board for ADS5295EVM operation?

The ADS5295EVM requires the TSW1400EVM for LVDS data capture and GUI-based control. They connect via P10 (ADS5295EVM) to J3 (TSW1400EVM); without TSW1400EVM, raw LVDS output cannot be acquired or analyzed. The ADS5295EVM itself does not include onboard data storage or USB-based streaming capability - TSW1400EVM provides the essential deserialization and PC interface layer for ADS5295EVM functionality.

Does ADS5295EVM support external clock inputs, and how is it configured?

Yes, ADS5295EVM supports five distinct clock configurations documented in SLAU442 Table 3, including external single-ended CMOS (via SMA J8), transformer-coupled differential (via SMA J4), and buffered variants using CDCLVP1102 (U4). Configuration is achieved through precise jumper settings (JP13–JP20) - for example, JP15/JP17/JP16/JP18 set to 1–2 enables transformer-based external clock, while JP19/JP20/JP16/JP18 set to 2–3 selects external CMOS at J8. All modes are validated in the user's guide.

How is analog input handled for Channel 8 on ADS5295EVM?

ADS5295EVM provides two mutually exclusive input paths for Channel 8: default transformer-coupled (J6 populated with R171/R172) or amplifier-based (J16 used after installing R169/R170 and removing R171/R172 to enable THS4509 single-ended-to-differential conversion). This dual-path design allows evaluation of both passive and active front-end topologies - critical for optimizing SNR and dynamic range in real sensor or RF applications interfacing with ADS5295EVM.

What software is mandatory to operate ADS5295EVM, and where is it sourced?

The TSW1400 High Speed Data Converter Pro GUI (v2.0 or higher) is mandatory and must be installed from Texas Instruments' official website; the ADS5295-specific plug-in tab is included in the GUI installer package. No standalone firmware or driver installation is needed beyond this GUI - it auto-detects the TSW1400EVM and loads the correct FPGA configuration and ADS5295 register map. The ADS5295EVM has no independent software stack; all control flows through the GUI's "ADS5295 GUI" tab.

Can ADS5295EVM be powered solely from USB, or does it require external supply?

ADS5295EVM requires an external +5-V DC power supply delivering up to 1.5 A - USB1 provides only communication and cannot power the board. Power is applied via P1 (barrel jack) or directly across TP_VP (+5 V) and TP2 (GND). LED_+5V (green) and LED33VA (orange) illuminate upon correct power application, confirming proper rail sequencing. Attempting USB-only operation will result in no power to ADC or LDOs and failure to initialize.
