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 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 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%
Down Spread of 0.5% for PCI, LPC and 66 MHz clocks
Industrial and commercial temperature ranges available
