W215B Datasheet (Cypress Semiconductor) - Notebook PC system Frequency Generator

W215B, Notebook PC system Frequency Generator

W215B CPU Outputs 0 through 3: These four CPU outputs are controlled by the CPU_STOP# control pin.

Output voltage swing is controlled by voltage applied to VDDQ2.

PCI Bus Outputs 0 through 5: These six PCI outputs are controlled by the PCI_STOP# control pin.

Output voltage swing is controlled by v
