AMD Geode Clock Source
Description
The MK1491-06 is a low-cost, low-jitter,
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.
The device has multiple power-down modes to reduce
power consumption.
Features
Packaged in 28-pin SOIC or in 28-pin SSOP
Available in Pb (lead) free
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
Multiple power down modes
Low EMI Enable pin reduces EMI radiation on PCI
clocks (patented)
Operating voltage of 3.3 V ±5%
