Arrow has evaluation boards for data conversion systems

The TSW1405EVM and TSW1406EVM have been developed jointly by Texas Instruments and Lattice Semiconductor, and feature Lattice fpgas and TI a/d and d/a converters. The TSW1405EVM is a low cost data capture board that can be used to evaluate TI's high speed a/d converters, while the TSW1406EVM is a pattern generator card for d/a converters. Both boards support a high speed lvds bus capable of providing/receiving 16bit samples at 1.0gs/s. The platforms support a 64k sample depth with the ability to collect data on up to eight channels concurrently. Each card features a LatticeECP3 fpga, which interfaces directly with the converter. To help jump start designs, Lattice and TI have worked together to implement LatticeECP3 HDL design files for a number of TI d/a converterss and a/d converters, including the 14bit, 250ms/s, single channel ADS4149 and ADS61B49, and dual channel ADS4249 and ADS62P49. The TSW1405EVM and TSW1406EVM are each supported by a software package that features an intuitive, easy to use graphical user interface. Set up and operation is achieved via a single, mini usb cable attached to the host pc. Data is transmitted and power drawn over this connection. In addition to stocking the evaluation kits for sale, Arrow is also making them available through its Testdrive programme, which enables engineers to evaluate selected development tools free of charge for one month.
