ALPHA CPCI-2IPC-6U – CompactPCI 6U Bus Motherboard Module | ALPHA Industrial Platform
Engineering Background
The ALPHA CPCI-2IPC-6U is a 6U-form-factor CompactPCI (CPCI) bus motherboard module engineered for high-reliability industrial computing environments. Designed to IEEE 1101.10/1101.11 mechanical standards and compliant with the PICMG 2.0 CompactPCI specification, this backplane module serves as the passive interconnect backbone for multi-slot IPC chassis deployments in process control, power automation, and transportation infrastructure.
Product Positioning
Targeted at procurement engineers and system integrators who require a proven, slot-compatible backplane for ALPHA-series CompactPCI single-board computers and peripheral cards. The CPCI-2IPC-6U provides a deterministic, noise-immune bus architecture that outperforms passive VME and ISA alternatives in EMI-dense industrial environments.

Engineering Advantages
- Passive Backplane Architecture: No active components on the bus plane — eliminates single-point failure risk and simplifies MTBF calculations for SIL-rated systems.
- Hot-Swap Ready: Supports CompactPCI hot-swap (PICMG 2.1) when paired with compliant SBCs, enabling live maintenance without system shutdown.
- High EMI Immunity: Ground plane isolation and shielded connector shrouds suppress conducted and radiated interference in high-voltage switchgear environments.
- Compact 2-Slot Density: Optimized for space-constrained 6U chassis where a full 8-slot backplane is unnecessary, reducing BOM cost and chassis depth.
- Long-Term Availability: ALPHA maintains multi-year production commitments for industrial platforms, supporting 10+ year system lifecycles.
System Architecture & Signal Flow
The CPCI-2IPC-6U implements a star-topology PCI bus with the system slot (slot 1) acting as the bus arbiter host. The peripheral slot (slot 2) connects via the J1 (32-bit PCI) and J2 (user-defined I/O) connectors. Power distribution rails (+5 V / +3.3 V / ±12 V) are routed through dedicated copper planes with decoupling capacitor arrays at each slot position. The backplane accepts standard 6U CompactPCI cards with front-panel I/O extraction handles per IEEE 1101.11.
Signal integrity is maintained through controlled-impedance traces (50 Ω ± 10%) and series termination resistors on all PCI clock and data lines, ensuring clean bus transitions at 33 MHz across the full industrial temperature range.

Technical FAQ
Q: Is the CPCI-2IPC-6U compatible with 64-bit CompactPCI cards?
A: The backplane implements a 32-bit PCI bus. 64-bit CPCI cards can be installed in the peripheral slot but will operate at 32-bit width.
Q: Can this backplane be used with non-ALPHA SBCs?
A: Yes. Any PICMG 2.0-compliant CompactPCI single-board computer will be electrically compatible. Mechanical fit depends on the chassis vendor.
Q: What is the maximum power dissipation per slot?
A: The backplane is rated for up to 25 W per slot at +5 V, subject to chassis cooling capacity.
Q: Do you provide datasheet or test reports?
A: Yes. Contact support@konmask.com to request the ALPHA CPCI-2IPC-6U datasheet and available test documentation.
