MK1491-06 Datasheet | Integrated Circuit Systems

CS5530 Geode ™ Description The MK1491-06 is a low cost, low jitter, high performance clock synthesizer for National Semiconductor CS5530 based puter and portable 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 and AC97 audio clocks, 24 MHz and 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. MK1491-06 Clock Source Features - Packaged in 28 pin, 300 mil wide SOIC or in 28 pin, 150 mil wide SSOP - Provides all critical timing for the National...
