Boards for Roach
The ROACH (Reconfigurable Open ArchitectureComputing Hardware) board family is a series of FPGA boards developed by UC Berkeley's CASPER (Collaboration for Astronomy Signal Processing and Electronics Research) group. https://casper.berkeley.edu/wiki/Hardware
These boards incorporate a large FPGA (Xilinx Virtex-5 in ROACH-1, or Virtex-6 in ROACH-2), memory, high-speed (10Gb/s) interconnect, and a standardized interface for data converters, allowing the development of highly compute-intensive instruments for radio astronomy and other scientific applications. CASPER maintains a large gateware library to permit streamlined implementation of complex designs using a high-level (Matlab Simulink) tool flow.
Over the last several years I've developed a number of data conversion boards and a frequency conversion board for the ROACH family. The hardware and gateware designs are all open-source: schematics are available here, and source code is available on the CASPER website. I build small quantities of some of these boards and offer them for sale, and sometimes have some in stock.
Intermediate frequency board. Provides local oscillator generation, clock generation, quadrature frequency upmixing and downmixing, settable attenuation in the 2 to 6.8 GHz range. Used for Kinetic Inductance Detector systems.
