General Description Features

ICS9159-14

Frequency Generator and Integrated Buffer for PENTIUM™

ICS9159-14 Rev B 3/16/00

Block Diagram

The ICS9159-14 generates all clocks required for high speed

RISC or CISC microprocessor systems such as 486, Pentium,

PowerPC,Ô etc. Four different reference frequency multiply-

ing factors are externally selectable with smooth frequency

transitions. These multiplying factors can be customized for

specific applications.

High drive BCLK outputs provide typically greater than 1V/

ns slew rate into 30pF loads. PCLK outputs provide typically

better than 1V/ns slew rate into 20pF loads while maintaining

±5% duty cycle.

• Generates up to four processor and six bus clocks, plus

disk, USB and reference clocks

• Synchronous clocks skew matched to 250ps window on

PCLKs and 500ps window on BCLKs

• 3.0V - 5.5V supply range

• 28-pin SOIC package

Pentium is a trademark of Intel Corporation.

PowerPC is a trademark of Motorola Corporation.
