Description
CPU Clock Outputs 0 through 1: These two CPU clocks run at a frequency set by SEL100/66#.
Features
- Maximized EMI suppression using Cypress’s Spread Spectrum technology.
- Reduces measured EMI by as much as 10 dB.
- I2C programmable to 153 MHz (16 selectable frequencies).
- Two skew-controlled copies of CPU output.
- SEL100/66# selects CPU frequency (100 or 66.8 MHz).
- Seven copies of PCI output (synchronous w/CPU output).
- One copy of 14.31818-MHz IOAPIC output.
- One copy of 48-MHz USB output.
- Selectable 24-/48-MHz output.
