Arrow Electronics is making available a pair of evaluation modules that will assist designers in the selection of parts for – and the development of – data conversion systems. The TSW1405EVM and TSW1406EVM have been developed jointly by Texas Instruments (TI) and Lattice Semiconductor and feature Lattice FPGAs and TI analogue-to-digital converters (ADCs) and digital-to-analogue converters (DACs), respectively. Arrow is the only distributor to support both TI and Lattice in Europe and a technical team that is able to assist in all aspects of the solutions has been set up.
The TSW1405EVM is a low-cost data capture board that can be used to evaluate some of TI’s high-speed ADCs. The TSW1406EVM is a pattern generator card for DACs. Both boards support a high-speed LVDS bus capable of providing/receiving 16-bit samples at 1.0 GSPS. The platforms support a 64-k 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 DACs and ADCs, including the 14-bit, 250-MSPS, single-channel ADS4149 and ADS61B49, and dual-channel ADS4249 and ADS62P49; 12-bit, 1000-MSPS, dual-channel ADS5400; 12-bit, 500-MSPS, single-channel ADS5463; and 11-bit, 200 MSPS, quad-channel ADS58C48.
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.
