Advanced ADC module with built-in processing resource is launched

Sundance Digital Signal Processing Inc., a leading provider of high performance signal processing and reconfigurable multiprocessor systems today introduced the DSP464 as 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.

The DSP464 continues Sundance DSP’s convention of easy access to interoperable, modular signal processing design. It can be used across an array of carriers and platforms including VME, cPCI and Advanced TCA (ATCA) to deliver the highest levels of design performance and operational flexibility. 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.

“The speed, accuracy and feature rich specification of DSP464 makes it a compelling solution for applications where the continuous acquisition of analogue signals and distribution of digital data to PCI and multi-gigabit interfaces are critical”, said Nory Nakhaee, CEO of Sundance DSP Inc. “With the DSP464 being supported by the PARS design environment, engineers can rapidly develop their system in Matlab/ Simulink and do not need to rely upon pre-defined 3rd party IP for FPGA design tasks.”

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. 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.

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.
