ICS9147-09 Datasheet (Integrated Circuit Systems) - Frequency Generator & Integrated Buffers

ICS9147-09, Frequency Generator & Integrated Buffers

The ICS9147-09 generates all clocks required for high speed RISC or CISC microprocessor systems such as Intel PentiumPro,AMD or Cyrix processors.

Four bidirectional I/O pins (FS0, FS1, FS2, BSEL) are latched at power-on to the functionality table.

The Six BUS clocks can be selected as either synchro

ICS9147-09 Features

* Total of 15 CPU speed clocks: - Two copies of CPU clock with VDDL (2.5 to 3.3V) - Twelve (12) SDRAM (3.3v) plus one CPUH/AGP (3.3V) clocks Six copies of BUS clock (synchronous with CPU clock/2 or asynchronous 32 MHz) 250ps output skew window for CPU andSDRAM clocks and 500ps window BUS clocks. CPU
