W210 - Cypress Semiconductor

W210 Spread Spectrum FTG for VIA K7 Chipset

CPU Clock Output 0: CPUT0 and CPUC0 are the differential CPU clock outputs for the K7 processor. CPUT_CS is the open-drain clock output for the chipset. It has the same phase relationship as CPUT0. PCI Clock Outputs 2 through 5: These four PCI clock outputs are controlled by the PWRDWN# control pin. Frequency is set by FS0:3 inputs or through serial input in.
