REQ signals should have pull-Ups to Vio. See Application Notes 55 , 58 , 60 for further details. Yes, you can have the secondary bus running at similar speed at the primary, or you can have the secondary bus running at half the speed of the primary bus.
If both are high, then the secondary will run at the same speed as the primary bus. If either one of them is low, then the secondary bus will run at half the speed of the primary bus. More importantly, some other card might do this to you if it is designed for 33 MHz but plugged into a normally 66 MHz bus. Address space is reserved in multiples of 1 Mb for the prefetchable and non-prefetchable memory spaces.
Yes, you can plug it in a bit slot. The system will automatically resize the slot to bit, all transfers will occur at bit data width. The other unused clocks can be unconnected. By default all the clocks are enabled; unused clocks can also be turned off at the Secondary Clock Control Register configuration register offset 68h, bits Either could work, so long as the total decoupling capacitance is provided. Our general guideline is to decouple power entering the board with.
Yes, a Hot swap controller is needed to ramp up the power as needed. It will also shut down if there is something wrong and there is too much current flowing through the Vcc planes. Yes, the center pad on the bottom is a ground pad, and must be connected to the ground. It is recommended that a few vias be designed in the board layout for adequate connection. Our bridge doesn't need a Pericom specific device driver. Linux Red Hat 7 supported our bridge with no driver from us, using a default pci-pci bridge driver.
Generally the system BIOS in non plug and play environment will configure the bridge -- that is, assign PCI bus number, enumerate detect and assign address ranges devices on the secondary buses, and update the memory ranges assigned to each bus. The OS does this for plug and play systems. Once this much configuring is done, the bridge can forward transactions in either direction without further Pericom-specific drivers being needed.
For the Windows and Linux environments the bridge uses the generic bridge driver already part of the OS kernel. You'll want to determine temperature at the die junction, but that involves first knowing the power, the thermal resistance theta Ja of the part, and the ambient air temperature.
Peak traffic generates the following current at the bridge: Peak ICC 3. Theta Ja for the NA package is See Packaging Mechanicals for more information. Yes, all these guidelines are available in the Hardware implementation Guides. Please refer to Bridges. Yes, all these guidelines are available in the Schematics and Layout guidelines for the See Application Note The D and x family of bridges are transparent bridges.
Yes, PI7C9X supports Hot-Plug function, but only the system supports with compatible hardware, software, and connectors.
Please refer to the following specification for details:. The device uses the default values in the registers. PI7C9X has internal clock source available for use shown in the table below. External clock source is not needed. If the system needs to use external clock source, please refer the Clock Scheme section of the datasheet. If it is a regular modem it is just a matter of uninstalling it and any drivers through Device Manager, shutting down and pulling the modem.
If it is an AMR then do the same about uninstalling but then you will need to disable it in the bios probably located under "Integrated Peripherals". Thanks for youadvice mate. I have disabled the PCI to Channel Bridge via the device manager, this has stopped the problem upon restarting. So again thanks for your reply and advice.
