ICS9159C-02CW28中文资料ICST数据手册PDF规格书

General Description

The ICS9159C-02 generates all clocks required for high speed RISC or CISC microprocessor systems such as 486, Pentium, PowerPC,™ etc. Four different reference frequency multiplying factors are externally selectable with smooth frequency transitions. These multiplying factors can be customized for specific applications. A test mode is provided to drive all clocks directly.

Features

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

• Synchronous clocks skew matched to 250ps window on PCLKs and 500ps window on BCLKs

• Test clock mode eases system design

• Custom configurations available:

Output frequency ranges to 100 MHz on options

Selectable multiplying and processor/bus ratios

Stop clock control stops clock glitch-free; available as mask option

• 3.0V - 5.5V supply range

• 28-pin SOIC package

Applications

• Ideal for high-speed RISC or CISC systems such as 486, Pentium, PowerPC, etc.
