A digital I/O module connects low-voltage differential signaling (LVDS) I/O to a Virtex-6 FPGA. This Cobalt module provides 32 LVDS differential input or output pairs plus LVDS clock, data valid and flow control signals via an easy access front panel 80-pin connector routed to the Virtex-6 FPGA.

LVDS used in the Model 71610 from Pentek is a general purpose digital interface operating at very high speeds over inexpensive twisted-pair or flat ribbon copper cables. It is popular for many common control or data capture applications such as high-speed video, graphics, video camera data transfers and general purpose computer buses. The standard built-in data capture and data generation facilities of the Model 71610 make it a suitable turnkey solution for developing and deploying custom FPGA processing algorithms.

Data can be pulled from devices such as sensors, data converters, custom digital systems or spectrum analyzers and then processed, decoded or formatted in the Virtex-6 FPGA before delivery to the host system processor. Likewise, signals from the host can be processed and formatted by the FPGA before delivery to the LVDS output.

The Model 71610 is a VITA 42 XMC (switched mezzanine card) module that can plug into carriers such as VPX, CompactPCI, AMC (Advanced Mezzanine Card) and PCI Express. The Model 71610 supports x4 PCIe on the primary P15 XMC connector. The secondary P16 XMC connector supports dual 4X or single 8X user-installed gigabit serial interfaces, such as Aurora, PCIe or Serial RapidIO. The Model 71610 has an optional PMC P14 connector with 20 pairs of LVDS connections to the FPGA for custom I/O to the carrier.

Pentek GateFlow FPGA Design Kits allow users to develop and install their own custom IP for data processing. The kits include full VHDL source code for factory installed intellectual property (IP) functions, so developers can easily add new functions by incorporating additional FPGA IP modules. Pentek’s ReadyFlow board support packages, with high-level C-callable library functions and device drivers, are available for Windows and Linux operating systems. Pricing starts at $9,495 and the Model 71610 is available in XMC, VPX, CompactPCI, AMC and PCI Express and rugged form factors.
