The Abaco Systems / Ramix PMC239/F is a PCI-to-PMC adapter that enables integration of PMC (PCI Mezzanine Card) modules into PCI-based systems. The adapter bridges IEEE 1386-compliant PMC modules to PCI host interfaces, supporting both 32-bit and 64-bit PCI slots with flexible voltage signaling across 3.3V and 5V domains.
– Technical Specifications
• PCI Interface: 32-bit and 64-bit PCI slot compatibility
• PMC Module Support: IEEE 1386 standard mezzanine cards
• Voltage Signaling: 3.3V and 5V PMC card support; 3.3V and 5V PCI slot compatibility
• Power Generation: +3.3V supply for PMC module operation
• Fan Cooling: 5V, 1W MagLev fan; user-disconnectable
• Debug Interface: 64-bit user I/O mapping to PMC P4 connector
• Form Factor: PCI edge connector, IEEE 1386 standard
– Key Features
• Dual-voltage signaling eliminates compatibility barriers between 3.3V and 5V PMC cards and PCI slots
• On-board +3.3V regulation for PMC power distribution
• Integral MagLev cooling fan reduces external thermal management requirements
• Optional fan operation allows deployment in passive configurations
• Debug connector provides direct I/O access for in-system testing and signal monitoring
• Compact PCI-slot form factor preserves host bandwidth and system real estate
– Typical Applications
• Laboratory development and PMC module prototyping
• Integration testing of PMC-based functionality in PCI environments
• Evaluation of third-party PMC hardware within legacy PCI systems
– Compatibility & Integration
The adapter accepts PMC modules with 3.3V or 5V signaling specifications and installs into corresponding PCI slots. Voltage compatibility is determined by the installed PMC card—3.3V-only PMC cards require 3.3V-capable PCI slots, while 5V-only PMC cards require 5V-capable slots. The PMC239/F generates its own +3.3V rail, eliminating external power supply requirements for the mezzanine module.
