Block Diagram
Pentium/ProTM System Clock Chip
9148-02 Rev C 1/26/99
Pentium is a trademark on Intel Corporation.
Generates system clocks for CPU, IOAPIC, SDRAM,
PCI, plus 14.314 MHz REF(0:1), USB, Plus Super I/O
Supports single or dual processor systems
I2C serial configuration interface provides output clock
disabling and other functions
MODE input pin selects optional power management
input control pins
Two fixed outputs separately selectable as
24 or 48MHz
Separate 2.5V and 3.3V supply pins
2.5V or 3.3V outputs: CPU, IOAPIC
3.3Voutputs: SDRAM, PCI, REF, 48/24 MHz
CPU 3.3_2.5# logic pin to adjust output strength
No power supply sequence requirements
Uses external 14.318MHz crystal
48pin300milSSOP
Output enable register
for serial port control:
1 = enable
0 = disable
The ICS9148-02 is a Clock Synthesizer chip for Pentium and
PentiumPro CPU based Desktop/Notebook systems that will
provide all necessary clock timing.
Features include four CPU, seven PCI and eight SDRAM
clocks. Two reference outputs are available equal to the
crystal frequency. Additionally, the device meets the Pentium
power-up stabilization, which requires that CPU and PCI
clocks be stable within 2ms after power-up.
PWR_DWN# pin allows low power mode by stopping crystal
OSC and PLL stages. For optional power management,
CPU_STOP# can stop CPU (0:3) clocks and PCI_STOP#
will stop PCICLK (0:5) clocks. CPU and IOAPIC output
buffer strength controlled by CPU 3.3_2.5# pin to match
VDDL voltage.
High drive CPUCLK outputs typically provide greater than 1
V/ns slew rate into 20pF loads. PCICLK outputs typically
provide better than 1V/ns slew rate into 30pF loads while
maintaining 50±5% duty cycle. The REF clock outputs typically
provide better than 0.5V/ns slew rates.
The ICS9148-02 accepts a 14.318MHz reference crystal or
clock as its input and runs on a 3.3V core supply.
