## Main Features
|
|
|
|
|
|
\* 4-lane PCIe (Gennum GN4124)
|
|
|
\* FMC slot with low pin count (LPC) connector
|
|
|
o Vadj fixed to 2.5V
|
|
|
o No dedicated clock signals from Carrier to FMC (only available on HPC
|
|
|
pins)
|
|
|
o LPC cheaper than HPC and also easier to mount
|
|
|
o FMC connectivity: all 34 differential pairs connected, 1 GTP
|
|
|
transceiver with clock, 2 clock pairs, JTAG
|
|
|
\* 1 Xilinx Spartan6 FPGA (XC6SLX150T-3FGG900C)
|
|
|
\* Simple clocking resources
|
|
|
o 1 10-280 MHz I2C Programmable XO Oscillator (Silicon Labs Si570)
|
|
|
o 1 25 MHz TCXO controlled by a DAC with SPI interface (AD5662)
|
|
|
o 1 20 MHz VCXO controlled by a DAC with SPI interface (AD5662)
|
|
|
o 1 low-jitter frequency synthesizer (TI CDCM61004, fixed configuration,
|
|
|
Fout=125MHz)
|
|
|
\* On board memory
|
|
|
o A 2Gbit DDR3
|
|
|
o 1 SPI 32Mbit flash PROM for multiboot FPGA powerup configuration,
|
|
|
storage of the FPGA firmware or of critical data
|
|
|
\* Front panel containing
|
|
|
o 1 Small Formfactor Pluggable (SFP) cage for fibre-optic transceiver

|
o FMC front panel
|
|
|
\* Internal connectors
|
|
|
o 1 JTAG header for Xilinx programming during debugging
|
|
|
o 1 mini USB AB (USB-UART bridge)
|
|
|
\* FPGA configuration. The FPGA can optionally be programmed from:
|
|
|
o GN4124 SPRIO interface (loaded by software driver at startup)
|
|
|
o JTAG header
|
|
|
o SPI 32Mbit flash PROM
|
|
|
o selectable by GN4124 GPIO. Default option would be loading via the SPI
