A new rugged FPGA Mezzanine Card module is a quad-channel 500 MSPS 14-bit analog input card. The FMC-518 from Curtiss-Wright Controls Embedded Computing features Intersil’s new ISLA214P50 14-bit, 500 MSPS analog-to-digital converter, and enables I/O devices to be directly coupled to a host FPGA. 

By providing direct ADC connection to the host FPGA, this compact card ensures maximum throughput and enables multiple channels and boards to be synchronized. The FMC-518 speeds and simplifies the integration of FPGAs into embedded system designs. The low-latency, high-bandwidth module eliminates data bottlenecks. The card is designed for use in demanding military applications such as Signal Intelligence (SIGINT), Direction Finding (DF) and Radar that require high-speed, high-resolution ADC components as part of a digital receiver. 

FMC format (VITA 57) is supported on a wide range of CWCEC FPGA-based host boards, with or without local CPUs, which are designed to process the FMC-518’s I/O data with high-bandwidth, low-latency paths. The host FPGA, CPU and high-performance I/O is a suitable platform for the next generation of digital receivers.

The FMC-518’s four ADC devices connect through the module’s high-bandwidth FMC connector to an FPGA-based host board to maximize data throughput and minimize 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, so not only are ADC devices synchronously sampled, but the data pipeline is coherent too. 

The FMC-518 supports four analog inputs through its 50Ω MMCX type front panel connectors. The analog inputs are single-ended and are coupled to Intersil ISLA214P50 ADCs using a balun for AC coupling configuration to produce the broadband differential input required by the devices. The FMC-518, available in both air-cooled and conduction-cooled rugged versions, is easily and quickly integrated onto open standards-based FPGA host boards.
