National Semiconductor and Xilinx introduced an integrated development platform that accelerates the design of complex, gigahertz-speed communications and test and measurement systems. The platform includes the Xilinx's Virtex-4 FPGA, which is optimized for reduced power and superior signal integrity, and the ADC08D1500, National Semiconductor's best-in-class, low-power, 3 Gsample/s analog-to-digital converter (ADC). The board is also available with any of the other converters from National's gigahertz-speed ADC family.
The development platform, in a plastic enclosure, requires only a power source and USB connection in order to collect and store data from any input signal, and upload test results to a PC. The platform is designed with functional blocks, including the ADC and FPGA; the LVDS interconnect between the ADC and FPGA; analog input networks to the ADC using baluns and differential amplifiers; on-board system clocking using a PLL and VCO; complete power supply design; and temperature monitoring circuitry. Each of these blocks can be reused by designers to significantly speed the development process.
The FPGA has several unused gates that can be programmed for proprietary firmware development; an expansion header for easy connection to FPGA I/Os; and a logic analyzer header connected to the FPGA for debugging. All of this allows designers to concurrently develop hardware and FPGA software without having to select and test individual components or utilize external test equipment.
The fully featured development platform with the ADC08D1500 and Virtex-4 FPGA is available now for $3800. To order the development platform, visit www.xilinx.national.com.
