FMC-516

The FMC-516 is a Quad Channel FPGA Mezzanine Card with 250 MSPS 16-bit analog input. It 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 Quad Channel. The FMC (VITA 57) specification allows I/O devices to be directly coupled to a host FPGA. This characteristic positions the FMC card as an optimal choice for a digital receiver front-end card.

On the FMC-516, 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 both an onboard programmable sample clock generator as well as an external reference input. Multiple FMC-516 Quad Channel boards can be synchronized to improve the number of input channels through the use of trigger input/output signals directly under the control of the FPGA. It can be used on platforms like CHAMP-WB or CHAMP-FX4.

The Quad Channel FPGA Mezzanine Card, FMC-516 supports four analog inputs through 50Ohm 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 Quad Channel FPGA Mezzanine Card is offered in both rugged air-cooled and conduction-cooled versions, and it can be synchronized with multiple FMC-516 modules to deliver coherent sampling for a scalable solution.
