FMC-518 Quad 500MSPS 14b ADC FMC

The FMC-518 is a quad channel 500 MSPS 14-bit analog input FPGA Mezzanine Card (FMC). The FMC (VITA 57) specification allows I/O devices to be directly coupled to a host FPGA. This makes the FMC-518 an ideal digital receiver front end. On the FMC-518, the four ADC devices connect through the high bandwidth FMC connector to an FPGA-based host board which maximizes data throughput and minimizes latency.

The FMC-518 supports an onboard programmable sample clock generator as well as an external reference input. Multiple FMC-518 boards can be synchronized to increase the number of input channels through the use of trigger input/output signals directly under the control of the FPGA. The FMC-518 can be used on platforms like Curtiss-Wright Defense Solutions’ VPX6-473 (Triple Xilinx Virtex-7 with Zynq) or VPX6-474 (Xilinx Virtex-7) which provides processor nodes for a powerful digital receiver platform.

Analog Input
The FMC-518 supports four analog inputs through 500 MMCX type front panel connectors. The analog inputs are single-ended and are coupled to Intersil ISLA214P50 ADCs using a balun and AC coupling capacitor configuration to produce the broadband differential input required by the devices.

Clocks, Triggers & Synchronization
The FMC-518 ADC’s sample clock can be driven from either an external source or onboard programmable sample clock generator. The clock source is controlled by the host FPGA.

FusionXF Software/HDL Support
Curtiss-Wright’s FusionXF development kit includes software, HDL and utilities with examples and infrastructure for using the FMC-518 on each supported host.
