Enhanced ISA/PCI Backplane Specifications
Bus Architecture The ISA/PCI backplanes
allow the use of standard ISA Bus and PCI Local
Bus option cards. They accept standard ISA Bus
processors or PCI Industrial Manufacturers Group
(PICMG) compliant processors.
Printed Circuit Layers The backplane is a six-layer .062" thick
board. Three signal layers, +5 voltage layer,
+3.3 voltage layer, and one ground layer.
Muti-layer construction provides excellent noise
Bus Terminations Terminations provide a
method to prevent or minimize reflections and
interference on the bus. This can become a
significant factor on the ISA Bus with option
cards having non-standard load characteristics or
with long ISA Bus lengths. Installing
terminations is required only as needed by the
Power Connectors Power connection is available through one of
the following connectors: standard AT connector,
terminal block connector, 156 MTA connector.
Connector This connector provides
additional power capacity for power-intensive
Keyboard Connector Three keyboard connectors: two are 5-pin
headers and one is a standard AT 5-pin DIN
connector. These connections provide options for
front or rear-mounted keyboard connectors.
PCI-to-PCI Bridge This option supports more
than two PCI Local Bus slots, extending the
electrical loading limits of a single PCI Bus.
The PCI Buses operate independently, allowing for
communication within the same bus even if the
other PCI Bus is busy.
