概览

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.
  • Packaged in 28-pin (209 mil) SSOP
  • Available in Pb (lead) free annealed package
  • Provides all critical timing for the AMD GX2 companion chip
  • Four selectable PCI clocks
  • Three LPC interface clocks
  • One fixed 66 MHz clock
  • Two reference clocks
  • 48 MHz USB and 48 MHz I/O support
  • Power-down mode
  • Low EMI Enable reduces EMI radiation on PCI clocks, LCLKS, and 66 MHz clock
  • Operating voltage of 3.3 V
