Sundance SMT702 - Manual (Page 22)

Samples coming from the ADCs are also routed straight on the SHB connector (DDR
32-bit bus).
The following diagram shows the data path implemented in order to capture
samples from the ADCs:
Figure 7 - Data (samples) path.
The SMT702 comes with a piece of software, the SMT7002. It is a demo application
that shows how to set up the module and allows capturing samples into text files.
Source code of the SMT7002 is available to purchase under the product name
SMT7026.

PXI Express Bus
As standard, the SMT702 is a 3U PXI Express peripheral module, which means it
comes with two PXI Express connectors: XP4 (PXI timing and synchronisation
signals) and XP3 (x8 PCI Express and additional synchronisation signals). The
SMT702 dedicates 8 lanes to the PXI Express bus, which gives an effective
bandwidth per direction of 16Gb/s. It also implies core and user clocks to be 250
MHz. Note that not all PXIe Express chassis and controller can handle 8 lanes on
peripheral modules. Currently only 1 and 4 lanes are supported. The Express core
developed by Sundance and based on Xlinks is able to achieve over 700Mbytes per
second for a 4-lane core clocked at 250MHz and half of it when clocked at 125MHz.
The standard SMT702 can plug in any PXI Express Peripheral Slot or any PXI Express
Hybrid Slot (PXI Express chassis, such as the NI-1062Q from National Instrument or
equivalent).
