W149 Datasheet (Cypress Semiconductor) - 440BX AGPset Spread Spectrum Frequency Synthesizer

W149, 440BX AGPset Spread Spectrum Frequency Synthesizer

CPU Clock Outputs: See Tables 2 and 6 for detailed frequency information.

Output voltage swing is controlled by voltage applied to VDDQ2.

PCI Clock Outputs 1 through 5: These five PCI clock outputs are controlled by the PCI_STOP# control pin.

Output voltage swing is controlled by voltage applied to
