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
• **Data Transfer Rate:** Up to 247 MB/sec at 2.5 Gbit/sec
• **DMA Engine:** Single transactions up to 64 MB with onboard DMA controller; supports byte/word swapping for register and DMA operations
• **Interrupt Controller:** Integrated controller reports link failure, transaction completion, and buffer space requests
• **VME Compliance:** VME64x standard; supports A32/A24/A16 Master and Slave addressing modes
• **PCI Interface:** 64-bit, 33 MHz/66 MHz; 3.3 V signaling; acts as VME-to-PCI bridge
• **Power Supply:** 3.3 V and 5 V derived from VMEbus backplane
• **Form Factor:** 6U VME Eurocard
## Key Features
• Dual FPDP interfaces for parallel high-speed data paths
• Optional flow control prevents receiver data loss
• Point-to-point and broadcast chaining topology support
• PMC (PCI Mezzanine Card) slot architecture enables modular system expansion
• Flexible user I/O routing
• Minimal CPU overhead through dedicated DMA operation
## Typical Applications
• Digital signal processing (DSP) systems
• Real-time radar and sonar data processing
• Medical imaging acquisition and processing
• Telemetry and high-speed data logging
• VMEbus-based real-time control systems
## Compatibility & Integration
The FHAS-4900-00029 integrates into existing VMEbus architectures as a carrier for standard PMC modules, providing flexible interface expansion. VME64x compliance ensures backward compatibility with A32/A24/A16 addressing schemes. The onboard PCI bridge allows interoperability with host systems supporting 64-bit PCI bus operation at 33 MHz or 66 MHz speeds.
