"Onyx is a strategic extension of our successful Cobalt line," said Rodger Hosking, vice president of Pentek. "With higher-speed A/Ds and D/As, and tougher DSP algorithms, we needed more horsepower to keep pace. Pentek leveraged the modular architecture of the Cobalt family, along with the latest Xilinx FPGA technology, to provide customers a broader range of price and performance options and a future path for the most demanding signal processing applications." Hosking added that Pentek intends to release at least twelve additional Onyx family modules during 2012.
"Pentek is among the first customers to leverage the high-performance, low-power Virtex-7 FPGA family," said Brent Przybus, director of High-End FPGA platforms at Xilinx. "As with all our 28nm 7 Series FPGA families, our goal is to deliver a scalable, unified FPGA offering with optimized features to increase the performance and flexibility customers need at the lowest possible power consumption."
As the first in the Onyx product line, the Model 71760 exemplifies the relationship of the Onyx and Cobalt families. The Onyx Model 71760 shares many of the same architectural and front-end characteristics as the similar Cobalt Model 71660 module: a four-channel, 16-bit, 200 MHz A/D, external sample clock synchronization and a VITA 42.0 XMC-compatible switched fabric interface.
The similarity of the two families gives developers the opportunity to port software developed for Cobalt modules to the corresponding Onyx modules with a minimum of effort. All ReadyFlow tools work with both families, further simplifying the software development effort. Thus, developers will be able to migrate from Cobalt to Onyx modules as their performance needs increase, or begin development on Cobalt modules until release of the corresponding Onyx module.
Architectural enhancements in the Onyx family include a doubling of the DDR3 memory in both size and speed to 4 GB and 1600 MHz, respectively. The PCIe interface has been upgraded to Gen 3, delivering peak speeds up to 8 GB/sec. The 71760 FPGA comes preconfigured with a suite of built-in functions for data capture, synchronization, tagging and formatting, making the board an ideal turn-key interface for radar, communications or general data acquisition applications. For systems that require custom functions, IP can be developed using the Xilinx ISE Design Software and the Pentek GateFlow FPGA Design Kit, extending or even replacing the factory installed functions. The Onyx architecture now includes enhanced FPGA loading modes to simplify live reconfiguration.
