General Description
The ICS9158-07 is a low-cost frequency generator designed specifically for desktop and notebook PC applications. Four copies of the CPU clock are available and four copies of the BUS clock are available, elimating the need for an external buffer.
FEATUREs
• 8 skew-free, high drive CPU/BUS clocks
• Reference, floppy and keyboard clocks
• ±250ps skew between all outputs
• Less than ±250ps absolute jitter
• Outputs can drive up to 30pF load at 1.5V/ns
• 50±10% duty cycle
• Compatible with 486 and Pentium CPUs
• On-chip loop filter components
• 3.0V - 5.5V supply range
• 24-pin SOIC package
APPLICATIONs
Ideal for RISC or CISC systems such as 486, Pentium,™ PowerPC,™ etc., requiring multiple CPU and BUS clocks.
