The ADC-PMC is a Dual
PMC adapter for PCI. It
supports 64-bit 66MHz
primary and secondary
PCI via an Intel 21154
PCI-PCI bridge device.
Cooling fans allow integration
of high power Processor
PMC card. PMC Pn4 user
I/O connections can be
routed between the PMC
sites or can be connected
to an on-board I/O connector.

The ADC-PMC is based on the 21154 64-bit 66MHz PCI-PCI
bridge manufactured by Intel. This device supports 64
or 32 bit primary PCI and 64 or 32-bit secondary PCI.
The ADC-PMC provides two PMC sites with an optional
third site for debug purposes. Each of the two primary
PMC sites supports Pn4 IO with quick-switch isolation
to permit various IO combinations. A set of jumpers
on the board enables each of the quick-switch blocks.
The IO-Bus is 64 bits wide and connects to all 64 signals
from the Pn4 connector of each PMC site. Further, a
subset of the IO-Bus can be routed to an on-board header
through a quick-switch block that provides a level of
protection to the IO bus signals by limiting the external
signal levels.
