Single Board Computer Backplanes

Trenton Technology design and build an extensive range of dependable, high-performance backplanes / motherboards to complement the range of processors.

The multi-layer designs result in low noise performance. Extra power connectors provide greater power capacity for larger applications.

In addition, sockets are available for bus termination to help minimise reflections and interference on the bus. PCI Express, ISA, PCI and cPCI backplane solutions are available.

PICMG 1.0 Backplane Solutions

BP3/6/4 64-bit Backplane

The Trenton Technology BP3/6/4 is an example of the 64-bit backplane solutions available. It provides two ISA Bus slots for the use of standard ISA Bus option cards and ten PCI Local Bus slots for the use of standard PCI Local Bus option cards.

The Trenton BP3/6/4 backplane accepts a PICMG® 1.0 compliant processor. The backplane is a six-layer, .062" thick board with three separate signal layers: +5V, +3.3V and ground. Multi-layer backplane construction provides excellent noise immunity.

PCI-to-PCI Bridge

The PCI-to-PCI bridge supports the PCI Local Bus 2.1 specification. This bridge allows the PCI Local Buses to extend the electrical loading limits of a single PCI Bus and to operate independently, allowing for communication within the same bus even if the other PCI Buses are busy. The BP3/6/4 backplane has bus mastering capabilities on all ten PCI Local Bus slots.

The power indicators provide a convenient visual check for +5V, -5V, +12V, -12V and +3.3V power connections. The standard AT power connection is available through a 12-pin .156 MTA connector. Power connection for +3.3V is available through a 12-pin .156 MTA connector or an ATX connector (optional). Additional power capacity is available through a 6-pin .156 MTA connector.
