Note: cPCIBPMC3U32 is the replacement for cPCIBPMC3U64ET. The 64 bit bridges are EOL. This version is a 32 bit cPCI implementation. The design is industrial temperature. Filtering, power distribution, PMC location have been retained. The rear IO is now routed with controlled impedance, and matched length.
cPCIBPMC3U32 is a 3U 4HP PMC adapter for cPCI. One PMC position is provided with a 32 bit interface for both the PMC and the cPCI backplane. User programmable VIO on the PMC side of the bridge. High capacity mini-planes with filtering for 3.3 and 5V.

cPCIBPMC6UET" is a 6U 4HP version with two PMC positions. The 6U version has both PMC IO connectors routed with equal length traces to J3 and J5. A PIM Carrier is available for the 6U model to support rear panel IO.
cPCIBPMC3U32 ( cPCI to PMC ) adapter / carrier converter card provides the ability to install a PMC card into a standard cPCI slot. cPCIBPMC3U32 has a PMC card slot mounted to a universal 3U 4HP cPCI card. Suitable for 32 width with 33/ 66 MHz bus operation. cPCIBPMC3U32 can be installed into a 64 bit system without the RIO option in place. The PMC bezel connector is mounted though the cPCI mounting bracket. cPCIBPMC3U32 is an extended temperature design. -40C to +85C standard. Conformal Coating is an option.
PCI VIO is interconnected to the primary side of the bridge. The secondary side of the bridge has programmable VIO allowing 5V PMCs to be used in 3V systems and vice-versa. The voltage select pins are not installed on cPCIBPMC3U32. The bridge will automatically adapt to the PCI bus reference voltage. Many PMCs are "universal" and can work with 3.3 or 5V cPCI backplanes.
Power is routed from the cPCI to PMC connectors with mini-planes each of which is rated for more than the maximum PMC draw. 3.3, 5, VIO, +12, -12
cPCIBPMC3U32 has low internal power dissipation. The dissipation is a function of the frequency and load from the installed PMC. For PMCs with higher power dissipation or for use in chassis with low airflow the Zero Slot fan option is recommended. The fans does not require an added slot and provides about 5 CFM of air movement.
With 3U cPCI, J2 has two definitions - in a 64 bit PCI implementation J2 has the upper A/D and control signals, and in a 32 bit PCI implementation J2 has the rear panel IO. cPCIBPMC3U32 has the Pn4/Jn4 IO from the PMC connected to J2.
