Data capture and multiprocessing board uses Virtex-5 SX95T
May 20, 2010 // Colin Holland
Sundance Digital Signal Processing Inc., is using a Virtex-5 SX95T FPGA on the DSP464, the latest addition to its family of high performance ADC/DAC hardware solutions.
Designed for use in PMC/ XMC form factors, the DSP464 delivers multiprocessor capture and processing capabilities for single unit installation or cascade deployment in heterogeneous networks.
Optimized for wideband, low noise, signal processing applications the DSP464’s PCIe, PCI-X and Serial RapidIO interfaces allow the transfer of high bandwidth data to host systems.
It can be used across an array of carriers and platforms including VME, cPCI and Advanced TCA (ATCA) and application design is supported by PARS (Parallel Application from Rapid Simulation) that enables designers to generate system target code, including DSP codes, FPGA codes and all of the inter-processor communication and synchronization codes from a Simulink model.
To enable RF/IF rate pre-processing the DSP464 features Virtex-5 SX95T FPGA optimized for high performance DSP that includes 640 Xilinx XtremeDSP slices capable of delivering up to 352 GMACs. The FPGA can be custom programmed and reconfigured in the field using PARS and is also supported by a wide range of logic cores, filters and blocks.
To support high frequency digitization and wide dynamic range, Sundance DSP selected four channels of Linear Technology’s 130Msps, sampling 16-bit high-resolution multi-channel capture ADC that is capable of interleaved acquisition of 1 channel at 520 MS/s.
Optimized for gigahertz-plus communications processing performance and high-speed connectivity Freescale’s PowerQUICC III processor drives the primary XMC and has access to 512MB of DDR2 memory.
By implementing a flexible clock distribution circuit based on Analog Device’s AD9510 the DSP464 offers a system-wide synchronized clock, phase adjustment of the ADC and output clocks, and dual-channel quadrature sampling. On-board clock synthesis is based on the AD9540 Low-Jitter DDS synthesizer and coupled with a temperature-compensated reference oscillator, the clock generation is able to provide sub-Hz frequency resolution down to 10Hz accuracy.
DSP464 is targeted at the enterprise networking, telecom transmission and switching, 3G wireless infrastructure, storage and high-end imaging markets.
