Upgrade to the Mercury+ KX2

If you want to upgrade your current Mercury KX1 solution, then have a look at the Mercury+ KX2.


The Mercury KX1 module offers the best performance-to-price-ratio Xilinx Kintex-7 28nm FPGAs in conjunction with the latest high-speed standard interfaces like USB 3.0, PCIe Gen2 and Gigabit Ethernet.

With powerful FPGA and standard interfaces, many LVDS-capable I/Os, large DDR3 SDRAM and many high-speed DSP slices, the KX1 is as well-suited for high-end digital signal processing, communications and networking as it is for high-speed I/O applications.

The Mercury KX1 FPGA board reduces development effort, redesign risk and improves time-to-market.



  • Features the latest best performance-per-price Xilinx Kintex-7 28nm FPGA family
  • Provides a powerful and easy to use Cypress EZ-USB® FX3™ based USB 3.0 device interface
  • Provides dual Gigabit Ethernet PHYs for high-bandwidth/low-latency networking
  • Provides PCIe Gen2 x4 interface for high-speed data transfer
  • Smaller than a credit card
  • Available in industrial-grade temperature range


  • Vast amount of parallel processing power for DSP applications (up to 1540 DSP Slices at 650 MHz = 2 TMAC/s)
  • High-bandwidth data I/O due to the large number of available LVDS pairs
  • Simple and low-cost integration due to standard interfaces (USB 3.0, PCIe Gen2, Gigabit Ethernet), single supply voltage and 1.8V / 2.5V / 3.3V power outputs
  • High-bandwidth memory – two independent DDR3 SDRAM memory channels are ideal for most applications
  • Many IP cores are available from Xilinx, Enclustra and third parties.
  • Simplified carrier board design (typically 4 layers)


  • Xilinx Kintex-7 28nm FPGA in the 676-pin package
  • Small form factor (72 x 54 mm, dual 168-pin Hirose FX10 connectors)
  • 178 User IOs
    • 136 single-ended or differential I/Os
    • 22 single-ended, differential or analog I/Os (11 auxiliary differential analog channels)
    • 20 MGT signals (clock and data)
  • 64 MB Quad SPI Flash
  • Up to 2048 MB + 512 MB DDR3 SDRAM
  • Cypress EZ-USB FX3 USB 3.0 device interface
  • 4 × 6.6/10.3125 Gb/s MGTs with integrated PCIe Gen2 x4 interface
  • Dual Gigabit Ethernet PHYs
  • High-power 20A core power supply
  • Supply voltage 5 to 15V
