Pin Configuration
TheICS9148-11 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/nsslew
rateinto30pFloads.PCLKoutputstypicallyprovidebetterthan1V/
ns slew rate into 20pF loads while maintaining50±5% duty cycle.
The REF clock outputs typically provide better than 0.5V/ns slew
rates.
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
