General Description
The
ICS9159-05
is a low cost frequency generator designed
specifically for Pentium/Pentium Pro systems. The integrated
buffer minimizes skew and provides the early CPU clock required
by some chipsets such as the OPTi VIPER. A 14.318 MHz
XTAL oscillator provides the reference clock to generate
standard Pentium frequencies. The CPU clock makes gradual
frequency transitions without violating the PLL timing of
internal micro-processor clock multipliers.
Features
Four CPU clocks operate up to 66.6 MHz at 3.3V with
glitch-free start and stop plus smooth transitions

Block Diagram
The synchronous bus frequencies are selectable as CPU for
local bus or CPU/2 for PCI bus support. Green PC systems
are supported through power-down, doze, and glitch-free
stop clock modes.
3-6ns early CPU clock supports OPTi VIPER systems
Selection of 6 frequencies, tristate, or power-down
Six BUS clocks support local PCI bus operation
Skew window between synchronous outputs
Integrated buffer outputs drive up to 30pF loads
3.0V - 3.7V supply range
28-pin DIP or 28-pin 300-mil SOIC package

Applications
Ideal for green Pentium/Pentium Pro and 486 PCI
systems such as Pentium, PowerPC
etc.
