Adapter puts mezzanine cards in cPCI
slots
The cPCIBPMC3U64ET (cPCI to PMC) adapter/carrier convertor card provides the ability to install a PMC card into a standard cPCI slot.
By customer request Dynamic Engineering has developed two extended temperature versions of the popular cPCIBPMC design The design effort included switching to a new bridge to meet the temperature and timing requirements

The PCI-NECL-ASN1 supplies 20 ECL transmitters and 20 ECL receivers plus 12 TTL I/Os.
Connector board eases switch to SpaceWire
Novel SpaceWire connector board helps with the transition from custom cabling to SpaceWire standard cabling.
The new bridge brings new features including the ability to operate the PMC side at a higher clock rate than the cPCI side.
The new bridge also has built in features for local address spaces, using the PMC clock in monarch mode for the secondary side, and operating in transparent or nontransparent modes.
The designs are ready for all PMC applications.
The cPCIBPMC3U64ET has a PMC card slot mounted to a universal 3U 4HP cPCI card, and is suitable for 32/64bit with 33/66MHz bus operation.
The 3U card is wired for 64bit PCI operation with pullups on the control lines to allow use in a 32bit system.
The PMC bezel connector is mounted though the cPCI mounting bracket.
The cPCIBPMC3U64ET is an extended temperature design -40 to +85C as standard.
Conformal coating is an option.
The PCIbus is interconnected to the PMC via 64bit 66MHz capable layout.
The slower and more narrow device will determine the interface characteristics.
The supplied DIP-switch is used to control the bridge configuration.
The user can select the clock rate, on both buses and has access to the GPIO bits.
PME and the interrupt request lines are routed from the PMC to the cPCI connector.
The 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 the cPCIBPMC3U64ET.
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.
The secondary side has a shunt for the user to select 5 or 3V operation.
The cPCIBPMC3U64ET follows the PMC specs for maximum power consumption and heat dissipation.
The power is routed from the cPCI to PMC connectors with mini-planes each of which is rated for more than the maximum PMC draw.
The cPCIBPMC3U64ET is PMC compliant per the IEEE 1386 specification.
All Dynamic Engineering PMC Modules are compatible with the cPCIBPMC3U64ET.
The cPCIBPMC3U64ET is also cPCI compliant.
