General Description
The ICS9147-22 is a Clock Synthesizer chip for Pentium and PentiumPro plus Cyrix CPU based Desktop/Notebook systems that will provide all necessary clock timing.


FEATUREs
Generates system clocks for CPU, IOAPIC, SDRAM, PCI, plus 14.318 MHz (REF0:1), USB, Super I/O
Supports single or dual processor systems
Supports Intel 60, 66.8MHz, Cyrix 55, 75MHz plus 83.3 and 68MHz (Turbo of 66.6) speeds.
Synchronous clocks skew matched to 250ps window on CPU, SDRAM and 500ps window on PCI clocks
CPU clocks to PCI clocks skew 1-4ns (CPU early)
Two fixed outputs, 48MHz and 24 MHz
Separate 2.5V and 3.3V supply pins
  - 2.5V or 3.3V output: CPU, IOAPIC
  - 3.3V outputs: SDRAM, PCI, REF, 48/24 MHz 
No power supply sequence requirements
48 pin 300 mil SSOP
