High-Speed A-D I/O card with four high-performance wideband A-Ds

BittWare Inc. in Concord, N.H., is offering the Tetra-PMC+ Analog-to-Digital (A-D) I/O card. The Tetra-PMC+ (TRPM) board features four high-performance wideband A-Ds running as fast as 105 MHz, and an Altera Cyclone II field programmable gate array (FPGA) providing A-D control, data distribution, and front-end processing capabilities. BittWare’s TRPM board is a high-speed analog input board that provides data capture for four 14-bit A-D channels running at up to 105 MHz, streaming this data directly to an Altera Cyclone II reconfigurable FPGA. The Cyclone II provides control over the A-Ds and handles the distribution of the high-speed converted data while also providing configurable pre-processing of this data, enabling digital filtering, decimation, and digital down conversion (DDC). The data can be transferred to the base board over the PMC interface by the Cyclone II. When attached to one of BittWare’s hybrid signal processing boards, it supports BittWare’s PMC+ extensions, which includes the four link ports directly connected to the Cyclone II FPGA. The board clocking can either be from the external clock or the on-board oscillator and is user-configurable. BittWare offers software development tools that allow designers to easily develop application code and integrate the Tetra-PMC+ into their systems. For user-configured preprocessing, Altera provides a complete suite of development tools for the Cyclone II. BittWare also offers a Tetra developer’s kit for the Cyclone II that includes the source for the A-Ds and the link ports. For more information contact BittWare online at www.bittware.com.
