Curtiss-Wright / VMETRO DPIO-FI/32K FPDP Input PMC Module

The Curtiss-Wright/VMETRO DPIO-FI/32K is an FPDP Input PMC Module designed for high-speed data acquisition in demanding embedded computing environments. This single-wide PCI Mezzanine Card captures data from FPDP sources and interfaces directly with VME, cPCI, and other PMC-equipped host platforms via PCI Bus Revision 2.1 with DMA controllers. The module delivers sustained input throughput up to 160 MBytes/sec with PECL clock or 80 MBytes/sec with TTL clock, making it suitable for real-time signal processing and data logging applications.
