ICS9148-11
Frequency Generator & Integrated Buffers for PENTIUM
TM
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鹵
5% duty cycle.
The REF clock outputs typically provide better than 0.5V/ns slew
rates.
