MK1491-06

AMD Geode™ Clock Source

Description

Features

The MK1491-06 is a low-cost, low-jitter,

• Packaged in 28-pin SOIC or in 28-pin SSOP

• Available in Pb (lead) free

high-performance clock synthesizer for AMD’s

Geode-based computer and portable appliance

applications. Using patented analog Phased-Locked

Loop (PLL) techniques, the device accepts a 14.318

MHz crystal input to produce multiple output clocks. It

provides selectable PCI local bus and AC97 audio

clocks, 24 MHz and 48 MHz clocks for Super I/O and

USB, as well as multiple Reference outputs.

• Provides all critical timing for the AMD Geode

companion chip

• Four PCI clocks

• Selectable PCIF on up to 2 outputs

• Early PCI clock selectability

• Up to 4 Reference clocks

• 48 MHz USB and 24MHz SIO support

• AC97 audio clock

The device has multiple power-down modes to reduce

power consumption.

• Multiple power down modes

• Low EMI Enable pin reduces EMI radiation on PCI

clocks (patented)

• Operating voltage of 3.3 V 5ꢀ
