Hi,
I am considering using a VME Single Board Computer with a PCI Mezzanine
Card socket. The PMC socket is designed for operation with 5V PMC cards.
I require as much future I/O flexibility as possible and therefore I need
to know whether the bulk of the PMC cards on the market have 5V or 3.3V
or dual 5V/3.3V signalling voltage capabilities.
Does anyone have a good feel for what is out there and particularly what
percentage of PMC boards have 3.3V signal levels only? (I will be unable
to use 3.3V only PMCs with my Single Board Computer.)
Thankyou for your assistance,
Simon Cameron
