Features

The ICS9248-92 is a fully compliant timing solution for the

•

Generates system clocks for CPU, SDRAM, PCI, plus

14.318MHz REF(0:2), USB, PlusSuperI/O

I²C serial configuration interface provides output clock

disabling and other functions

Intel mobile 440BX/MX chipset requirements.

GeneralDescription:

FeaturesincludetwostrongCPU, sevenPCIandeightSDRAM

clocks. Three reference outputs are available equal to the

crystal frequency. Stronger drive CPUCLK outputs typically

provide greater than 1 V/ns slew rate into 20pF loads. This

device meets rise and fall requirements with 2 loads per CPU

output (ie, one clock to CPU and NB chipset, one clock to two

L2 cache inputs).

MODE input pin selects optional power management

•

Two fixed outputs separately selectable as 24 or 48MHz

2.5Voutputs:CPU

3.3Voutputs:SDRAM, PCI, REF, 48/24MHz

No power supply sequence requirements

Usesexternal14.318MHzcrystal

48pin240milTSSOPpackage

PWR_DWN# pin allows low power mode by stopping crystal

OSC and PLL stages. For optional power management,

CPU_STOP# can stop CPU (0:1) clocks and PCI_STOP# will

stopPCICLK(0:5)clocks

Output enable register

for serial port control:

1 = enable

0 = disable

PCICLK outputs typically provide better than 1V/ns slew rate

into30pFloadswhilemaintaining50±5%dutycycle. TheREF

clock outputs typically provide better than 0.5V/ns slew rates.

The ICS9248-92 accepts a 14.318MHz reference crystal or

clock as its input and runs on a 3.3V core supply.
