CP390
1.2 Board Interfaces
CompactPCI Interface
The CompactPCI interface connector J1 (CON1) provides all the necessary signals for
data transfer as defined by PCI Specification Rev. 2.1.
The CP390 is routed to the CompactPCI backplane by means of the Intel 21150 PCI-to-
PCI bridge which interfaces the board with a data path width of 32-bit and a speed up to
33MHz.
PMC Interface
The PMC interface of the CP390 provides an easy way to extend a CompactPCI system
via the wide array of interfaces and functions which are available on PMC modules pro-
duced by the entire range of PMC vendors. The secondary side of the PCI-to-PCI
Bridge provides a 32-bit wide PCI data path with a speed of up to 33MHz which is
routed to the onboard connectors Jn1 and Jn2. These connectors also provide the
power supply for the PMC module. The interface has been designed to comply with the
IEEE 1386.1 specification which defines a PCI electrical interface for the CMC (Com-
mon Mezzanine Card) form factor.
Additionally, the CP390-HS (Hotswap version) has been designed to comply with the
CPCI Hotswap specification PICMG 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.
