1 Introduction
The SMT791 is a 3U PXI Express digitizer board capable of sampling two analogue
inputs at 1GSPS with a resolution of 8 bits. An e2v/ATMEL dual channel ADC
(AT84AD001)
This digitizer board features several external I/O interfaces too.
The main features of the SMT791 are:
• Two ADC channel inputs (ideal for I and Q channel applications),
• 1GHz sampling frequency,
• 8-bit data resolution,
• Custom clock and trigger inputs via external SMA connectors on the front-
panel,
• PCI Express transfer to the Host PC at 400Mbytes/s,
• On-board Flash memory to store the module configuration/application,
• Xilinx FPGA JTAG header.
device performs the analogue-to-digital conversion.
More on-board features are available like:
• One 64-bit wide data bank of DDR2 memory: the bank uses four 16-bit wide
devices. Running this memory at 175MHz provides a maximum access speed
of over 2.8Gbytes/s.
• Fibre optic modules: Two FPGA serial interfaces are presented here using
Stratos Lightwave 568-LTK-LT12-H modules. These interfaces support
2.5Gbits/s operation,
• RSL connector: for data streaming to external Hardware,
• SATA connectors: two FPGA serial interfaces are used (support SATA I/II),
• A single RJ45 connector provides a 10/100/1000 Ethernet interface. The
RJ45 connects directly to a Marvell 88E1116 PHY, which is interfaced to the
FPGA.
• Two SHB connectors: for LVTTL GPIOs or data streaming to external device,
• Four RS232 (accessible from the Xilinx Spartan-3 FPGA or the USB controller),
• Reset push-button (to re-initialise the carrier board).
