General Description
Features
ICS9159-12
Frequency Generator and Buffers for Mobile Pentium Systems
ICS9159-12RevB071797P
Block Diagram
The ICS9159-12 generates all clocks required for mobile
microprocessor systems based on Pentium/Mobile Triton
chip sets. Three different reference frequency multiplying
factors are externally selectable with smooth frequency
transitions. These multiplying factors can be customized
for specific plications. A test mode is provided to drive all
clocks directly.
High drive BCLK outputs provide greater than 1V/ns slew
rate into 30pF loads. PCLK outputs provide better than 1V/
ns slew rate into 20pF loads while maintaining ±5% duty
cycle.
Generates 14 clocks including processor, disk
and reference
Meets all Pentium/Mobile Triton 82430MX
requirments
Independent buffers provide 4 and 6 clock copies
Buffered clocks skew matched to ±250ps
Buffer inputs are 5V tolerant
Test clock mode eases system design
Selectable multiplying and processor/bus ratios
Custom configurations available
3.0V- 5.5V supply range
28pin, .209" SSOP package
