General Description

The ICS9158-05 is a low cost frequency generator designed specifically to clock Pentium systems using the Triton chip set. Three copies of the CPU clock are available at 50, 60, or 66.7 MHz. Five copies of the synchronous BUS clock run at half the CPU frequency. A 14.318 MHz REFCLK, 12 MHz, KEYBD, and 24 MHz FLOPPY clock are also provided.

Features

? 3 CPU and 5 synchronous BUS clocks

? 50/60/66 MHz and glitch-free stop clock selections

? ±250ps skew between all synchronous outputs

? Outputs drive up to 30pF load with 1V/ns slew

? 2-5ns early CPU clocks support Triton chip set

? Compatible with 486 and Pentium CPUs

? Consumes less than 10μA in power-down mode

? 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 synchronous BUS clocks.
