W130 Product details

Description

W130 CPU Clock Outputs 0 through 5: These six CPU clock outputs are controlled by the CPU_STOP# control pin.Output voltage swing is controlled by voltage applied to VDDQ2. PCI Bus Clock Outputs 1 through 7: These seven PCI clock outputs are controlled by the PCI_STOP# control pin.Output voltage swing is controlled by voltage applied to VDDQ3. Fixed PCI Clock Output: Unlike PCI1:7 outputs, this output is not controlled by the PCI_STOP# control pin.Output voltage swing is controlled by voltag
