概要

説明

The MK1491-09 is a low cost, low jitter, high performance clock synthesizer for AMD's Geode™ GX2 processor for information appliance applications. Using patented analog Phase-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 a power down mode to reduce power consumption.
