The Curtiss-Wright / Systran A-H-PR-BFPMSLXC FibreXtreme Serial FPDP CMC Module is a high-performance communication interface card that converts between serial and parallel FPDP data streams. Housed in a Common Mezzanine Card form factor, it implements ANSI/VITA 17.1-2003 sFPDP protocol to support demanding data acquisition, signal processing, and sensor integration applications. The module delivers deterministic, low-latency data transfer without CPU overhead through an optimized DMA engine and extends connectivity up to 50 km over fiber optic cable.

• Byte/word swapping support for system flexibility
• Parallel FPDP port (80-pin, configurable input/output) on carrier boards for bidirectional serial-to-parallel conversion
• Multiple operational topologies: point-to-point, broadcast chaining, copy mode, loop mode
• Integrated interrupt controller reports link failure, transaction completion, and buffer space requests
• Optional flow control prevents receiver data loss
• Supports frame-based data structures with SYNC variants and error detection
• Bidirectional communication enables recorded data playback for additional processing
## Typical Applications
Digital signal processing, radar and sonar systems, medical imaging, video production, and high-throughput sensor data acquisition requiring deterministic real-time performance.
## Compatibility & Integration
The module integrates with carrier boards supporting PCIe and XMC interfaces. Serial FPDP connections accept both fiber optic and copper media, with fiber enabling extended reach for distributed system architectures.
