ICS9248-192
Frequency Timing Generator for Transmeta Systems
Recommended Application:
Transmeta
Output Features:
• 1CPU(2.5V or 3.3V selectable) up to 66.6MHz &
overclocking of 66MHz.
• 6 PCI (3.3V) @ 33.3MHz (all are free running
selectable).
• 1 REF (3.3V) at 14.318MHz.
• 1 48MHz (3.3V).
• 1 24_48MHz selectable output.
Features:
• Supports Spread Spectrum modulation for CPU and
PCI clocks, default -0.4 downspread.
• Efficient Power management scheme through stop
clocks and power down modes.
• Uses external 14.318MHz crystal, no external load
cap required for CL=18pF crystal.
• 28-pin TSSOP package, 4.40mm (173mil).
Skew Characteristics:
• CPU – CPU <175ps
• PCI – PCI < 500ps
• CPU(early) – PCI = 1.5ns – 4ns.
