Texas Instruments ADS5294EVM

Overview

ADS5294EVM from Texas Instruments is an evaluation module designed to characterize the ADS5294 8-channel, 14-bit, 80-MSPS analog-to-digital converter under real-world signal, clock, reference, and power supply conditions. It integrates onboard CMOS clock generation, configurable LVDS output interface (2-wire mode), and dual-supply regulation for +3.3V analog, +1.8V analog, and +1.8V digital rails. The board supports full-channel ramp pattern validation and single-tone FFT analysis via TSW1400EVM interfacing.

For engineers reviewing the ADS5294EVM datasheet, ADS5294EVM pinout, ADS5294EVM application, or ADS5294EVM equivalent, this page delivers verified hardware configuration details, USB driver setup guidance, jumper-based clock source selection (onboard CMOS, external CMOS, transformer-coupled, buffered, or differential), LED power-status indicators, and test point access for SCLK/SDA/SEN/SDOUT serial control and VCM/CDC_VTH monitoring.

Technical Context

The ADS5294EVM implements a complete signal chain interface for the ADS5294 ADC, including SMA-connected analog inputs for all eight channels, on-board voltage regulation with JP4/JP5/JP6 enable jumpers, and LVDS deserialization support via P10 connector to the TSW1400EVM. It uses the CDCLVP1102RGT clock buffer for differential clock conditioning in selected modes.

USB communication is handled by the FT245RL USB FIFO IC, enabling host PC control of ADC configuration registers and data capture coordination. Power sequencing is managed through discrete +5-V input at P1, with onboard LDOs generating precise +3.3V and +1.8V rails monitored by four dedicated LEDs (green for +5V, +1.8VA, +1.8VD; orange for +3.3VA).

FAQ

What is the primary function of the ADS5294EVM?

The ADS5294EVM is a dedicated evaluation platform for the ADS5294 8-channel, 14-bit, 80-MSPS analog-to-digital converter. It enables engineers to validate dynamic performance-including SNR, SFDR, and ENOB-under controlled signal, clock, power, and reference conditions. The ADS5294EVM interfaces directly with the TSW1400EVM for LVDS data capture and supports both time-domain ramp testing and frequency-domain single-tone FFT analysis using the HSDCPro GUI.

Which software tools are required to operate the ADS5294EVM?

Operation of the ADS5294EVM requires two software components: the ADS5294 GUI (for device register configuration, test pattern selection, and power/reset control) and the High Speed Data Converter Pro (HSDCPro) GUI (for data capture, time-domain visualization, and FFT analysis). Both tools are distributed by Texas Instruments and depend on the FT245RL USB driver installed via the CDM 2.04.06 WHQL-certified package referenced in the SLAU355A user's guide for ADS5294EVM.

How does the ADS5294EVM connect to a host PC and the TSW1400EVM?

The ADS5294EVM connects to the host PC via USB1 (J11) using the onboard FT245RL USB FIFO IC, enabling bidirectional register access and control. It connects to the TSW1400EVM via the P10 LVDS interface connector, which carries serialized ADC output data. The TSW1400EVM then routes captured data to the PC over its own USB port (J8), allowing synchronized operation of both ADS5294EVM and TSW1400EVM within the HSDCPro environment.

What clocking options does the ADS5294EVM support?

The ADS5294EVM supports five distinct ADC clock configurations: (1) onboard 80-MHz CMOS oscillator (default), (2) external single-ended CMOS via SMA J8, (3) transformer-coupled external clock via SMA J4, (4) buffered clock using CDCLVP1102RGT with onboard oscillator input, and (5) buffered clock with external CMOS input. Selection is implemented via combinations of JP13–JP20 jumpers, as documented in Table 3 of the SLAU355A user's guide.

What power supplies and monitoring features are built into the ADS5294EVM?

The ADS5294EVM accepts a single +5-V DC input at P1 and generates three regulated rails: +3.3V analog (enabled by JP4), +1.8V analog (JP6), and +1.8V digital (JP5). Four LEDs provide real-time status: LED_+5V (green), LED1.8VA (green), LED1.8VD (green), and LED3.3VA (orange). Test points TP22 (VCM = 0.95 V) and TP6 (CDC_VTH = 1.65 V) allow direct measurement of critical bias voltages during evaluation.
