Other Parts Discussed in Thread: PCI2050B

Hi,

    In my new PCI card design, In the Controller card Primary  PCI bus from PowerPC processor is connected to PCI2050B. The Secondary PCI bus from PCI2050B is connected to 8 different PCI target boards which are less than 2.5" away from PCI2050B. My question is can I go ahead with this configuration, that case what is the maximum nuber of PCI targets the Bridge can support?

Note that  PCI2050B secondar bus is connected to a cPCI J1 connector, the PCI signals will run through this connector to a backplane and from backplane it is connected to pci target boards through that card's cPCI connector.

Thanks and Regards,

Basil Alias

    The PCI2050B is capable of supporting up to 9 secondary devices.

    from the data sheet: The PCI2050B provides two-tier internal arbitration for up to nine secondary bus masters and may be implemented with an external bus arbiter.
