@Michael, it's not just the IP: you're going to need a "High Speed Serial Connection". The humble [cheap] Spartan-6 isn't good enough; according to Xilinx you need at least a Virtex-6. Remember to factor that into the price.

See: http://www.xilinx.com/products/intellectual-property/EF-DI-JESD204.htm

Throw in stripline / microstrip effects for data clocking in the GHz, and I DO fear JESD204B is not for me. I'll use slower clocks, a parallel output, have a cheap Spartan-6 FPGA within 5cm (2 inch) and try to match trace lengths.

High speed serial may be deisred for specialized applications. However, it may introduce new set of problem. Does fast edges of this communication link compromises performance of high resolution precision ADC and DAC.

Hi Michael-

Altera and Xilinx both offer JESD204B IP for their respective FPGA families.  Please contact them for their pricing models.

Thanks,  Ian Beavers

Which FPGA makers have JESD IP, and for how much? (free I hope)

LATEST ARCHIVED BROADCAST
David Patterson, known for his pioneering research that led to RAID, clusters and more, is part of a team at UC Berkeley that recently made its RISC-V processor architecture an open source hardware offering. We talk with Patterson and one of his colleagues behind the effort about the opportunities they see, what new kinds of designs they hope to enable and what it means for today’s commercial processor giants such as Intel, ARM and Imagination Technologies.
