TSW140x High Speed Data Capture/Pattern Generator Card

The Texas Instruments TSW1400 Evaluation Module (EVM) is a next generation of pattern generator and data capture card used to evaluate performances of a wide range of Texas Instruments (TI) high-speed analog-to-digital converters (ADC) and digital-to-analog converters (DAC). For an ADC, capturing the sampled data over an LVDS interface when using a high-quality, low-jitter clock, and a high-quality input frequency, the TSW1400 can be used to demonstrate data sheet performance specifications. Together with the accompanying LabVIEW™ based High Speed Data Converter Pro Graphic User Interface (HSDC Pro GUI), it is a complete system that captures and evaluates data samples from ADC EVMs and generates and sends desired test patterns to DAC EVMs.

The TSW1405 is a low cost data capture card with limited capabilities as compared with the TSW1400. The TSW1405 supports pattern capture for most LVDS format TI ADC EVMs, but with a capture buffer limitation of 64K samples. The TSW1405 draws its power from the USB connection to the PC for easy setup and operation. HSDC Pro GUI supports the TSW1405 as well, making for a consistent feel across the different platforms.

The TSW1406 is a low cost pattern generator card with limited capabilities as compared with the TSW1400. The TSW1406 supports pattern generation for most LVDS format TI DAC EVMs, but with a pattern limitation of 64K samples. The TSW1406 draws its power from the USB connection to the PC for easy setup and operation. HSDC Pro GUI supports the TSW1406 as well.

This document describes the hardware aspect of the TSW140x EVMs along with a few quick start examples of how to use these boards with ADC and DAC EVMs. For a thorough explanation of the operation of the GUI, download the HSDC Pro GUI User's Guide (SLWU087) from the TI website.
