Texas Instruments ADS42LB69EVM

Overview

ADS42LB69EVM from Texas Instruments is an evaluation module designed exclusively for the ADS42LB69 dual-channel, 16-bit, 250-MSPS analog-to-digital converter. It provides transformer-coupled analog and clock inputs, LVDS output interface, and full software control via USB-connected GUI for rapid ADC characterization in high-speed data acquisition systems.

For engineers reviewing the ADS42LB69EVM datasheet, ADS42LB69EVM pinout, ADS42LB69EVM application, or ADS42LB69EVM equivalent, this EVM enables direct performance validation of the ADS42LB69 ADC - including SNR, SFDR, and jitter sensitivity - when paired with the TSW1400EVM capture card and HSDCPro software under real-world signal conditions up to 250 MHz.

Technical Context

The ADS42LB69EVM implements a complete signal chain interface for the ADS42LB69 ADC, featuring SMA-connected single-ended analog inputs (A_INP, B_INM), a 250-MHz-capable CLK_INM clock input, and an LVDS output connector for direct interfacing with the TSW1400EVM. Power is supplied via banana jacks (J8 = +3.3 V, J9 = GND), and configuration is handled through an FTDI-based USB link.

It supports full register-level programming of the ADS42LB69 via the ADS42LBx9 GUI v2.0, including power-down mode control (JP3/JP4), reset (SW1), and sync input (SYNCIN). The board is compatible with FPGA development platforms using FMC or HSMC connectors when used with appropriate interposer cards.

FAQ

What is the primary function of the ADS42LB69EVM?

The ADS42LB69EVM is an evaluation module built specifically to characterize the ADS42LB69 dual-channel, 16-bit, 250-MSPS analog-to-digital converter. It provides all necessary signal conditioning, clocking, power delivery, and digital interface circuitry - including transformer-coupled analog inputs, LVDS output, and USB-based GUI control - to validate the ADS42LB69's dynamic performance (e.g., SNR, SFDR, ENOB) under real-world operating conditions.

Which host hardware is required to operate the ADS42LB69EVM?

The ADS42LB69EVM requires the TSW1400EVM data capture card as its primary host interface; the two boards connect directly via the LVDS J7 header on the ADS42LB69EVM and the ADC interface on the TSW1400EVM. It also supports FPGA development platforms with FMC or HSMC connectors when used with TI-recommended interposer cards, and relies on a Windows PC running the ADS42LBx9 GUI v2.0 and HSDCPro software.

Does the ADS42LB69EVM support both ADS42LB49 and ADS42LB69 devices?

Yes - the ADS42LB69EVM is part of the ADS42LBx9EVM family and is physically and electrically compatible with both the ADS42LB49 (14-bit) and ADS42LB69 (16-bit) converters. The same board layout, connectors, and GUI support both devices; users select the target device in the HSDCPro software's "Select ADC" dropdown menu during setup, and firmware is automatically loaded based on the selected part.

What are the power requirements for the ADS42LB69EVM?

The ADS42LB69EVM requires a clean, regulated +3.3 V DC supply delivered via banana jacks J8 (+3.3 V) and J9 (GND). No onboard voltage regulation is provided - external supply must meet low-noise specifications recommended in the ADS42LB69 datasheet to preserve ADC performance. USB power is used only for the FTDI interface and GUI communication, not for ADC operation.

Can the ADS42LB69EVM be used without the TSW1400EVM?

No - the ADS42LB69EVM does not include on-board memory or data capture capability. Its LVDS output is designed exclusively for connection to the TSW1400EVM (or compatible FPGA platforms via interposers). Without that host, the ADS42LB69EVM can configure and power the ADS42LB69 via USB but cannot acquire, store, or process sampled data; full evaluation requires the TSW1400EVM and HSDCPro software stack.
