MK1491-09 - AMD Geode GX2 Clock Source

Datasheet Summary

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.

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.
