General Description

The ICS9158-04 is a low cost frequency generator designed specifically for desktop and notebook PC applications. Up to six copies of the CPU clock are available, and five or six copies of the BUS clock are available depending on the status of the frequency select pins, which eliminates the need for an external buffer.

Features

? 11 skew-free, high drive CPU/BUS clocks

? Up to 66 MHz at 3.3V

? –250ps skew between all outputs

? Outputs can drive up to 30pF load and 25mA

? 50–10 duty cycle

? Compatible with 486 and Pentium CPUs

? Selectable 5/6 or 6/5 CPU/BUS output ratio

? 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.
