ICS9158-03
Frequency Generator and Integrated Buffer
General Description
The ICS9158-03 is a low-cost frequency generator designed
specifically for desktop and notebook PC applications. Eight
copies of the CPU clock are available.
Each high drive (40mA) output is capable for driving a 30pF
load and has a typical duty cycle of 50/50. The clock
outputs are skew-controlled to within ±250ps.
The ICS9158-03 makes a gradual transition between
frequencies, so that it meets the Intel cycle-to-cycle timing
specification for 486 and Pentium systems.
Features
8 skew-free, high drive CPU/BUS clocks
Up to 100 MHz output
±250ps skew between all outputs
Outputs can drive up to 30pF load and 40mA
50±10% duty cycle
Compatible with 486 and Pentium CPUs
On-chip loop filter components
4.5V - 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.
