AMD Geode GX2 Clock Source

MK1491-09
AMD Geode™ GX2 Clock Source
Description
The MK1491-09 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 clocks, 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 SSOP (209 mil body)
Available in Pb (lead) free packaged
Provides all critical timing for the AMD Geode
companion chip
Four selectable PCI clocks
Three LPC interface clocks
One Fixed 66 MHz clock
2 Reference clocks
48 MHz USB and 48 MHz IO support
Power down mode
Low EMI Enable pin reduces EMI radiation on PCI
clocks, LCLKS, and 66 MHz clock
Operating voltage of 3.3 V ±5%
