The Technobox 1447 is a 32-bit, 33 MHz PMC to PCI adapter that bridges PCI Mezzanine Card (PMC) modules into standard PCI slots within desktop and server systems. This short-length PCI board enables PMC functionality without requiring separate PCI-based designs, delivering cost-effective integration of specialized PMC capabilities into conventional PCI architectures.
Technical Specifications
• Bus Interface: PCI, 32-bit, 33 MHz
• PMC Support: 32-bit PMC modules per IEEE 1386
• Signaling Voltage: 3.3 V and 5 V PCI bus compatible (keying pegs removed)
• Rear I/O Connector: 96-pin DIN connector bridging to PMC 64-pin user I/O (J4/P4)
• Form Factor: Short-length PCI board with 2.5 mm aluminum panel bracket, 0.5 mm chamfered edge
• Connectors: Standard PCI edge connector; standard PMC module connector
– Key Features
• Dual-voltage support eliminates keying restrictions for mixed 3.3 V / 5 V PMC modules
• 96-pin DIN rear I/O connector enables internal rear connectivity when supported by PMC design
• Aluminum bracket panel mimics VME-bus and equivalent host mechanical form factors
• Cost-optimized design omits development features (LEDs, clamping diodes, logic analyzer headers, Side 1 probing access)
• Minimized power architecture reduces design overhead
– Typical Applications
• Desktop and server PMC module integration without system redesign
• PMC supplier product expansion into standard PCI platforms
• Systems requiring specialized PMC functionality in conventional PCI slots
– Compatibility & Integration
The adapter accommodates 32-bit PMC modules in standard 32-bit, 33 MHz PCI slots. Single-adapter installation is recommended to minimize PCI signal stubbing; optimal placement is at the endmost PCI slot position. Supports standard PMC supply voltages (3.3 V, 5 V, +12 V, -12 V); auxiliary power connectors may accommodate higher-demand PMC requirements.
