V7668A-13100 GE V7668A 3U VME Single Board Computers

GE V7668A-13100 Single Board Computers

The GE V7668A-13100, also cataloged as the V7668A Single Board Computers, operates as a dedicated hardware component for high-performance embedded computing and real-time data processing within VME bus platforms. Powered by an Intel T7400 Core 2 Duo processor operating at 2.167 GHz, the board executes system instructions using 4 GB total system memory. Physical data transport across the system backplane relies on an IDT Universe II PCI-to-VME bridge, while four Gigabit Ethernet interfaces manage deterministic network communications and real-time field data transfer.

Hardware Specifications

Firmware Flash Compatibility & Backplane Integration

The GE V7668A-13100 maintains high backplane bus communication velocity via its dedicated IDT Universe II PCI-to-VME bridge chip, which translates internal PCI bus cycles into deterministic VME bus cycles. System hardware relies on low power consumption profiles ranging between 2.5 W and 5 W, minimizing heat buildup across high-density chassis configurations. Onboard AMIBIOS configurations maintain strict firmware flash compatibility with real-time operating systems, enabling rapid boot sequence execution directly from the 1 GB CompactFlash storage media. Integrated optical isolation barriers and passive R-C filtering networks prevent high-frequency electromagnetic interference from corrupting critical processor transactions.

Frequently Asked Questions

Q: How does the IDT Universe II bridge chip handle data arbitration across the VME backplane?

A: The IDT Universe II chip acts as a high-speed interface between the processor's local PCI bus and the external VMEbus architecture. It performs automatic bus master/slave arbitration, DMA data transfers, and cycle-by-cycle address translation to maintain deterministic data throughput without burdening the primary Core 2 Duo CPU.

Q: What are the memory slot constraints when replacing or expanding system RAM?

A: The module architecture uses a hybrid memory design featuring 2 GB of permanently soldered onboard memory combined with a single 200-pin SODIMM socket populated with a 2 GB module. System technicians must ensure replacement SODIMM modules match the speed and voltage parameters of the soldered memory array to avoid memory timing faults during boot execution.

Field Installation Guidelines

Slide the GE V7668A-13100 board into the designated single-slot 3U VME subrack position along the chassis card guides. Push the card firmly until the backplane connectors seat completely into the motherboard socket, then tighten top and bottom retaining screws to secure the front panel and establish ground continuity with the enclosure frame.

Attach high-speed network interfaces using shielded RJ45 Cat6 Ethernet cables to minimize ambient electrical noise. Route external RS-232 serial wires, USB cables, and PMC expansion connections through dedicated cable management paths, keeping signal wiring separated from high-voltage AC distribution circuits and relay control lines inside the cabinet.
