Advance Information W48S111-14
Spread Spectrum Desktop / Notebook System Frequency Generator
Features
• Maximized EMI suppression using IC WORKS’ Spread Spectrum Technology
• Reduces measured EMI by as much as 10dB • I2C programmable to 133MHz • Two skew-controlled copies of CPU output • SEL100/66# selects CPU frequency (100 or 66.8MHz) • Seven copies of PCI output (synchronous w/CPU output) • One copy of 14.31818 MHz IOAPIC output • One copy of 48MHz USB output • Selectable 24/48MHz clock is determined by resistor
straps on power up • One high drive output buffer that produces a copy of the
14.318MHz reference • Isolated core VDD pin for noise reduction
