Texas Instruments ADS5263EVM

Overview

ADS5263EVM from Texas Instruments is an evaluation module designed to characterize the ADS5263 quad-channel, 16-bit/14-bit analog-to-digital converter (ADC). It supports up to 80-MSPS sampling rate, provides transformer- and THS770006-amplifier-coupled analog input paths, includes onboard LVPECL clock buffering via CDCLVP1102, and interfaces to a PC via USB for register control and data capture using the TSW1400 high-speed LVDS deserializer card.

For engineers reviewing the ADS5263EVM datasheet, ADS5263EVM pinout, ADS5263EVM application, or ADS5263EVM equivalent, this page delivers verified hardware configuration details, USB/FIFO interface architecture, dual-clocking options (sine-wave transformer-coupled or LVPECL), analog input flexibility across four channels, and integration requirements with the TSW1400 capture system.

Technical Context

The ADS5263EVM implements a complete signal chain for evaluating the ADS5263 ADC, including configurable analog front-end paths (transformer or THS770006 amplifier per channel), dual-clock input modes (SMA J31 sine-wave + TC4-1W transformer or SMA J33 LVPECL + CDCLVP1102 buffer), and on-board power regulation (5 V → 3.3 V AVDD and 1.8 V LVDD).

It features a USB-to-parallel-FIFO bridge using the FT245RL IC, enabling register access and real-time ADC configuration via the ADS5263 GUI, while raw LVDS data output from the ADS5263 is routed to the TSW1400 capture card through a high-speed QTH connector (J8) for time- and frequency-domain analysis in the TSW GUI or HSDCPro software.

FAQ

What is the primary function of the ADS5263EVM?

The ADS5263EVM is an evaluation module built to fully assess the performance and functionality of the ADS5263 quad-channel, 16-bit/14-bit analog-to-digital converter. It provides all necessary circuitry-including analog input conditioning, clock distribution, power regulation, USB-based register control via FT245RL, and LVDS data output to the TSW1400 capture card-to enable comprehensive testing of the ADS5263 in real-world signal chain configurations.

Does the ADS5263EVM support both 16-bit and 14-bit ADC operation modes?

Yes, the ADS5263EVM supports both modes. The ADS5263 device itself offers selectable 16-bit (pins 1A–4A) or 14-bit (pins 1B–4B) conversion per channel. On the ADS5263EVM, each channel can be independently configured via zero-ohm resistor jumpers (e.g., R80/R81 for Channel 1A, R98/R99 for Channel 1B) to route either transformer-coupled or THS770006-amplified signals to the appropriate ADC input pins, enabling flexible evaluation of both resolution modes.

How does the ADS5263EVM connect to a host PC and what software is required?

The ADS5263EVM connects to a host PC via USB 2.0 using the onboard FT245RL USB-to-parallel-FIFO interface. It requires two complementary software tools: the ADS5263 GUI (for register-level configuration, debug mode, and command sequence scripting) and the TSW1400 GUI or HSDCPro (for capturing, visualizing, and analyzing LVDS data output from the ADS5263). Both are provided by Texas Instruments and require proper USB driver installation before first use.

Can the ADS5263EVM operate without the TSW1400 capture card?

No - the ADS5263EVM is not a standalone data acquisition system. Its LVDS digital outputs are routed exclusively to the TSW1400 capture card via the QTH-060-02-F-D-A connector (J8). While the ADS5263EVM enables full register control and analog signal conditioning, raw sampled data cannot be acquired or analyzed without the TSW1400 card and its associated GUI or HSDCPro software. The EVM and TSW1400 form a tightly integrated evaluation pair.

What clocking options does the ADS5263EVM provide for the ADS5263 ADC?

The ADS5263EVM provides two validated clocking paths: (1) a transformer-coupled sine-wave input via SMA connector J31, using the TC4-1W balun to generate differential LVDS-compatible clock signals; and (2) an LVPECL clock input via SMA connector J33, conditioned by the onboard CDCLVP1102 buffer. Users must reconfigure passive components (e.g., remove C59/C61, replace 0-Ω resistors with 0.1-µF caps) to switch between these modes, as documented in Section 2.2 of the SLAU344A user's guide.
