ICS9158-07
Frequency Generator and Integrated Buffer
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.
Each high drive (25mA) output is capable of driving a 30pF
load and has a typical duty cycle of 50/50. The clock outputs
are skew-controlled to within ±250ps.
The
ICS9158-07
makes a gradual transition between frequen-
cies, so that it meets the Intel cycle-to-cycle timing specifica-
tion for 486 and Pentium systems.
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.
