Simple VME FMC Carrier 7 (SVEC7)

Project description

The FMC VME Carrier is an FMC carrier in VME64x format that can hold two FMC cards and an SFP connector. Unlike on the SVEC, where it is based on, the FMC mezzanine slots use high-pin count (HPC) connectors. This board is optimised for cost and will be usable with most of the FMC cards designed within the OHR project (e.g. ADC cards, Fine Delay).

Main Features

  • VME64x interface
  • Two Low-Pin Count FMC slots
    • Vadj fixed to 2.5V
    • No dedicated clock signals from Carrier to FMC (as only available on HPC pins and use LPC)
    • FMC connectivity: all 34 differential pairs connected, 1 GTP transceiver with clock, 2 clock pairs, JTAG, I2C
  • Xilinx FPGAs
    • Application FPGA: Spartan-6 XC6SLX150T-3FGG900C
      • Direct connection to all resources such as VME64x, memories and FMC connectors
    • System FPGA: Spartan-6 XC6SLX9-2FTG256C
      • Provides VME bootloader, early oscillator/PLL config
      • Configuration Flash memory for both Main FPGA and Application FPGA configuration
  • FPGA configuration
    • From SPI flash or via VME
  • Clocking resources
    • 1x 10-280 MHz I2C Programmable XO Oscillator, starts up at 100 MHz (Silicon Labs Si570, freely usable)
    • 1x 25 MHz TCXO controlled by a DAC with SPI interface (AD5662, used by White Rabbit PTP core)
    • 1x 20 MHz VCXO controlled by a DAC with SPI interface (AD5662, used by White Rabbit PTP core)
    • 2x low-jitter frequency synthesizer/fanout (TI CDCM61004, fixed configuration, Fout=125 MHz, used by White Rabbit PTP core)
  • On-board memories
    • 2x 256 MByte (2 Gbit) DDR3 (16-bit bus, MT41J128M16JT-125)
    • 1x 128 Mbit SPI flash for FPGA firmware storage (M25P128-VME6GB)
