Curtiss-Wright / Systran FHAS-4900-00029 Dual FPDP VME Carrier Card

The Curtiss-Wright/Systran FHAS-4900-00029 is a 6U VME carrier card that bridges VMEbus and PCIbus architectures while delivering dual high-speed FPDP (Fast Parallel Data Protocol) interfaces. Purpose-built for high-throughput data acquisition and processing, the card sustains up to 247 MB/sec transfers at 2.5 Gbit/sec through an optimized Serial FPDP protocol, enabling deterministic, low-latency operation across demanding signal processing, radar, sonar, medical imaging, and telemetry platforms.

Technical Specifications
