Posted by John McHaleCHELMSFORD, Mass., 28 May 2011. Engineers at TEK Microsystems started shipping a product called QuiXilica Proteus-V6 that brings 5 SPS signal acquisition together with Xilinx Virtex-6 processing for applications based on VME and VXS.The device uses three Virtex-6 field programmable gate arrays (FPGAs) with two e2v EV10AQ190 10-bit A/D converters, with with sample accurate synchronization across multiple boards. It supports either two channels at 5 GSPS, four channels at 2.5 GSPS, or eight channels at 1.25 GSPS,. Each e2v EV10AQ190 ADC devices provide 10-bit resolution of either two channels at 5 GSPS, four channels at 2.5 GSPS, or eight channels at 1.25 GSPS. Each ADC uses a common clock and have an associated trigger/gate signal to enable coherent processing across multiple boards.The two front-end FPGAs are attached directly to the A/D converters, providing a high speed connection from the ADC to the FPGA. The other FPGA can support more processing or required protocol support for either front panel or backplane interfaces.
