Kintex7 XC7K160T-2FFG676 |
The HiRADDA set is composed of two boards : HiRADDA Core and HiRADDA Mezzanine.
HiSADDA is compatible with the FPGA Rack Backplane for interconnecting different boards with the help of the HVME16 version of the HES-SO Backplane Bus and the HES-SO VME IP Core.
Core features
Main board
- 4x A/D 24bits 4MSPS with 2 analog paths :
- Direct (differential - BW DC..1GHz)
- Through operationnal amplifier
- 1x Xilinx Kintex7 XC7K160T-2FFG676
- 162.24k logic cells, 25.35k slices (max 2.188Mb of distributed RAM)
- 11.7Mb block RAM (650x18Kb / 325x36Kb)
- 600 DSP Slices
- GTX
- 1x 100MHz quartz for work clock
- 2x SATA connector (for general purpose gigabit link - expermiental)
- 1x SSRAM (total: 4/8MiB, xxbit width)
- 2x 32MiB Serial QuadSPI NOR Flash (one reserved for FPGA programming)
- nx user LEDs
- nx user DIL Switches
- 1x JTAG Connector
- 1x DIN41612 VME Compatible Connector 3x32 pins (only HVME16) with CMOS AC termination on all signal pins (unsoldered - expermiental)
- 1x Low-jitter clock generator/distributor
- 1x external clock input
Mezzanine board
- 2x D/A 16bits xxxMSPS (Analog Devices AD9726), current source, with 2 analog paths :
- Direct (differential - BW DC..200MHz)
- Through balun/aop
- 1x USB2 (micro USB connector, FTDI FT232HL)
- 1x power supply
Power supply considerations
The following power rails are produced on board :
- +A5.0V (ADS1675)
- +D1.0V (FPGA Core)
- +D2.5V (SSRAM + FPGA BANK)
- +D3.0V (ADS1675 + FPGA BANK)
- +D3.3V (VME + FPGA BANK)
VME connector logic levels
The I/O bank which interfaces the VME connector is only 3.3V. Be careful with other FPGA Rack boards with 2.5V/3.3V jumper.
Programmation
This board can be programmed in 2 ways,
- First the FPGA can be directly programmed.
- Second the FPGA can be programmed via the onboard Flash memory (SPI x1/x4).
More explanation for FLASH programmation are available here.
Known issues
- None.
