FMC-516

Quad 250MSPS 16b ADC FMC that provides low latency, high-performance functionality necessary for applications such as Signal Intelligence (SIGINT), Electronic Warfare (EW) and RADAR.

Overview

The FMC-516 is a quad channel FPGA Mezzanine Card with 250 MSPS 16-bit analog input. The FMC-516 provides the low latency, high-performance functionality necessary for applications such as Signal Intelligence (SIGINT), Electronic Warfare (EW) and RADAR (including beamforming) through the density, speed and resolution of data delivered to the FPGA host through the FMC-516. The FMC (VITA 57) specification allows I/O devices to be directly coupled to a host FPGA. This makes the FMC516 an ideal digital receiver front end. On the FMC516, 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-516 supports an onboard programmable sample clock generator as well as an external reference input. Multiple FMC516 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-516 can be used on platforms like Curtiss-Wright Controls Defense Solutions’ FPE650 (quad Xilinx Virtex-5), HPE720 (MPC8641D/dual Virtex-5) or FPE320 (Xilinx Virtex-5) which provides processor nodes for a powerful digital receiver platform.

The quad channel FPGA Mezzanine Card, FMC-516  supports four analog inputs through 50Ω MMCX type front panel connectors. The analog inputs are single-ended and are coupled to Intersil ISLA216P25 ADCs using a balun and AC coupling capacitor configuration to produce the broadband differential input required by the devices.

The FMC-516, available in rugged air and conduction-cooled variations, can be synchronized with multiple FMC-516 modules to provide coherent sampling for a scalable solution.
