ICS9147-14 Datasheet | Integrated Circuit Systems

Integrated Circuit Systems, Inc. Frequency Generator & Integrated Buffers for PENTIUM/ProTM General Description The ICS9147-14 generates all clocks required for high speed RISC or CISC microprocessor systems such as Intel PentiumPro. Two bidirectional I/O pins (FS1,FS2) are latched at power-on to the functionality table, with FS0 selectable in real-time to toggle between conditions. • • • • • • • • • • • • • • • • • • • • Features High drive PCICLK and SDRAM outputs typically provide greater than 1 V/ns slew rate into 30 pF loads. CPU outputs typically provide better than 1V/ns slew rate into 20 pF loads while maintaining 50 ± 5% duty cycle. The REF clock outputs typically...
