The MK1491-06 is a low cost, low jitter, high performance clock synthesizer for National Semiconductor CS5530 based computer 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,.
• Packaged in 28 pin, 300 mil wide SOIC or in 28 pin, 150 mil wide SSOP
• Provides all critical timing for the National Semiconductor CS5530 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 .
