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 is determined by resistor straps on power-up

• One high-drive output buffer that produces a copy of the 14.318-MHz reference

• Isolated core VDD pin for noise reduction
