dSPACE – DS5203 FPGA Board

FPGA programmable per application

The DS5203 FPGA Board is designed for applications that require very fast, high-resolution signal preprocessing.

Overview

The DS5203 FPGA Board can be adapted to various tasks, so you can react flexibly to tougher requirements, such as signal conditioning, new interfaces, or speeding up

model parts. FPGAs are especially useful for relieving the processor board of tasks such as signal preprocessing during ECU development. Running at 100 MHz, the DS5203 board is ideal for application fields like engine knocking, cylinder pressure analyses, and electric drive projects. The DS5203 works closely together with the XSG model library.

 

Key Benefits

A field-programmable gate array (FPGA) is a semiconductor device consisting of configurable logic. The DS5203 FPGA Board features a powerful, freely programmable FPGA, the Xilinx Virtex®-5. In addition, it offers 6 ADC, 6 DAC and 16 digital I/O channels, and connection to the processor board via PHS bus. The number of I/O channels can be increased by piggyback modules.
