MK1491-06J - AMD Geode Clock Source

This page provides the datasheet information for the MK1491-06J, a member of the MK1491-06RLF AMD Geode Clock Source family.

Datasheet Summary

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.

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).
