Overview

Integrated Circuit Systems, Inc.
ICS9148-11 Frequency Generator & Integrated Buffers for PENTIUMTM General Description The ICS9148-11 generates all clocks required for high speed RISC or CISC microprocessor systems such as Intel PentiumPro.
An output enable pin is provided for testability.
MODE allows power management functions: CPU_STOP#, PCI_STOP# & PWR_DWN#.
High drive BCLK outputs typically provide greater than 1V/ns slew rate into 30 pF loads.
PCLK outputs typically provide better than 1V/ ns slew rate into 20 pF loads while maintaining 50± 5% duty cycle.
The REF clock outputs typically provide better than 0.
5V/ns slew rates.
Features Generates four processor, six bus, one 14.
31818MHz and 12 SDRAM clocks.
Synchronous clocks skew matched to 250ps window on CPU, SDRAM and 500ps window on BUS clocks.
CPUCLKs to BUS clocks skew 1-4 ns (CPU early) Test clock mode eases system design Custom configurations available VDD(1:3) - 3.
3V ±10% (inputs 5V tolerant w/series...
