2. Functional Description
2.1 Board Interfaces
2.1.1 PMC Slots
The two single-size PMC slots on the CP690HS provide an easy way to extend a CompactPCI
system via the wide array of interfaces and functions which are available from all PMC vendors.
The secondary (PMC) side of the PCI-to-PCI bridge provides a 32/64-bit wide PCI data path
with a speed of up to 66 MHz which is routed to the onboard connectors Jn1, Jn2 and Jn3.
These connectors also provide the power supply for the PMC module. The PMC slots have
been designed to comply with the IEEE 1386.1 specification, which defines a PCI electrical in-
terface for the CMC (Common Mezzanine Card) form factor.
The CP690HS has been designed to comply with the CompactPCI hot swap specification PIC-
MG 2.1 R1.0, which means that the power supply of the PMC modules will be ramped up and
a reset generated whenever the board is plugged into a running system. The CP690HS pro-
vides 3.3V (default) and 5V PMC PCI signaling environment.

Warning!
The PMC coding key must be set according to the chosen PMC voltage.
Care must be taken to ensure correct voltage configuration. Using an incorrect
signalling voltage may damage the PMC module.

The top two of each set of four PMC connectors
are for connection to a 32-bit PCI bus.
Note:
The upper and lower
sets of four connectors
are identical in function.
This connector raises the signal
capacity to 64-bit PCI bus.
