Description
The MK149109 is a lowcost, lowjitter, highperformance clock synthesizer for AMD's Geodebased computer and portable appliance applications.
It uses patented analog PhasedLocked Loop (PLL) techniques to accept a 14.318 MHz crystal input and produce multiple output clocks.
The device provides selectable PCI local bus clocks, 48 MHz clocks for Super I/O and USB, as well as multiple Reference outputs.
It has multiple powerdown modes to reduce power consumption.
Features
Packaged in a 28pin SSOP (209 mil body)
Pbfree, RoHS compliant package
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 I2C 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 ±15%
Down Spread of 0.5% for PCI, LPC, and 66 MHz clocks
Industrial and commercial temperature ranges available with Spread Option
Applications
AMD Geodebased computer and portable appliance applications
