Functional Description
3
The MCP750HA provides the 33 MHz clocks for each of the CompactPCI
slots. All clock source outputs are active when the MCP750HA is owner
of the CPCI bus.
The 21154 supports 3.3V or 5V signalling at the PCI busses with a separate
VIO pin for the primary and secondary bus buffers. The primary bus
signalling voltage is tied to +5 volts. The secondary bus signalling voltage
is tied to the CPCI bus VIO, so the MCP750HA is a universal board that
may operate in a +3.3V or +5V chassis.
PCI Expansion Connector (J4)
The expansion connector can be used to route the local PCI bus to a
secondary PCI-to-PCI bridge. In addition, signals needed by the Hot Swap
Controller/Bridge Module are routed through J3. Refer to the chassis
specific information found in the MCG chassis manual for your particular
product. A list of those manuals is included in

availability architecture implementation.
