General Description
Features
ICS9148-13
Block Diagram
Pentium is a trademark of Intel Corporation
Frequency Generator & Integrated Buffers for PENTIUMTM
9148-13 Rev A 020398
Pin Configuration
The ICS9148-13 generates all clocks required for high speed
RISC or CISC microprocessor systems such as Intel Pentium
and PentiumPro. An output enable is provided for testability.
Spread Spectrum is available to modulate the CPU and BUS
PLL (leaving the REF, 24, 48 MHz operating normally). The
SS_EN# pin enables the spreading when low. The SS_TYPE
pin choses ±0.5% (nominally) center spread or +0, -2%
(nominally) downspread modulation.
High drive BUS outputs typically provide greater than 1V/ns
slew rate into 30 pF loads. CPU 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 0.8/ns slew rates.
Generates twelve processor, six bus, two
14.31818MHz, 24MHz and one 48MHz clock for
USB support.
Synchronous clocks skew matched to 250ps window
on CPUs and 500 ps window on BUSs
CPU to BUS skew, 3.0 to 5.0ns (CPU Early)
3.0V - 3.7V supply range
48-pin SSOP package
