W196 Datasheet (Cypress Semiconductor) - Spread Spectrum FTG for 440BX and VIA Apollo Pro-133

W196, Spread Spectrum FTG for 440BX and VIA Apollo Pro-133

W196 CPU Clock Outputs 0 through 1: These two CPU clocks run at a frequency set by FS0:1 or the serial data interface.

See Table 1 and Table 5.

Output voltage swing is set by the voltage applied to VDDQ2.

PCI Bus Clock Outputs 1 through 6 and PCI_F: These seven PCI clock outputs run synchronously
