General Description
Features
ICS9159-13
Frequency Generator and Integrated Buffer for PENTIUM
ICS9159-13RevB060497P
Block Diagram
The ICS9159-13 generates all clocks required for high
speed RISC or CISC microprocessor systems such as 486,
Pentium, PowerPC, etc. Four different reference frequency
multiplying factors are externally selectable with smooth
frequency transitions. A test mode is provided to drive all
clocks directly.
High drive BCLK outputs provide typically greater than
1V/ns slew rate into 30pF loads. PCLK outputs provide
typically better than 1V/ns slew rate into 20pF loads while
maintaining 50±5% duty cycle.
Generates up to six processor and six bus clocks, plus
two reference clocks
Synchronous clocks skew matched to 250ps window
on PCLKs and 500ps window on BCLKs
Processor and bus clocks synchronized to each other,
PCLK to BCLK skew window 600ps max
Test clock mode eases system design
3.0V - 5.5V supply range
