ICS9147-16 Datasheet (Integrated Circuit Systems) - Frequency Generator & Integrated Buffers

ICS9147-16, Frequency Generator & Integrated Buffers

The ICS9147-16 generates all clocks required for high speed RISC or CISC microprocessor systems such as Intel PentiumPro.

Two different reference frequency multiplying factors are externally selectable with smooth frequency transitions.

Glitch-free Stop clock control is provided for CPU and BUS cloc
