The FMC-520 integrates two or four channels of analog output into embedded computing systems, dependant on the output conversion rate selected. The innovative design of the FMC-520, based on the emerging VITA 57 standard, makes it easier for developers to integrate FPGAs and analog output into their embedded system designs. Typical DSP applications for this module include Software Radio, Signal Intelligence (SIGINT) / Electronic Warfare (EW), Electronic Counter Measures (ECM), and Radar. The FMC-520 uses two Texas Instruments DAC5682Z DAC devices. Each device supports a single channel with an output rate of 1000MSPS or two channels at 500MSPS. Both data rates are with 16-bit resolution. The DAC device interfaces are routed to the FMC connector to enable an FPGA on a baseboard to directly control the output data flow. The high bandwidth connectivity of the FMC interface ensures that data can be transferred from the FPGA without compromising the throughput. The analog outputs are 50 Ohm AC coupled and connect through the front panel using MMCX connectors.
Clock and Trigger Signals
There is an on-board programmable VCXO which can be locked to an external 10MHz reference provided through the external clock input connector. The FMC can also provide an output signal from the clock circuit. External LVPECL compatible trigger input and outputs are provided and linked to the FPGA host. These signals can be used for a variety of purposes including triggering, gating, and multi-board synchronization dependant upon HDL application code.
FMC
The FMC/VITA 57 (draft) specification allows I/O devices that reside on an industry standard mezzanine card to be attached to, and directly controlled by, FPGAs that reside on a baseboard. The benefits are increased performance, higher bandwidth, reduced latency, lower cost and less complexity. To maximize data throughput and minimize latency, the FMC connector has many pins that support high-speed signals for moving data between the FMC and an FPGA on the baseboard.
FMC-520 Hosts
The FMC-520 can be fitted to our hosts including the FPE650, a quad Xilinx® Virtex®-5 VPX Processor board with dual FMC sites. The combination of the FMC-520 and a FPGA provides a high quality high performance solution in a single VPX/VPX-REDI slot.
The FMC-520 is supported by Curtiss-Wright's XF suite which includes software APIs for remote hosts and HDL examples.
