Renesas Electronics Corporation Application Specific Clock/Timing MK1491-09FLNTR

The MK1491-09FLNTR is a clock synthesizer designed for AMD Geode-based applications, offering a low-cost and low-jitter solution. It utilizes patented analog Phased-Locked Loop (PLL) technology and accepts a 14.318 MHz crystal input to generate multiple output clocks, including selectable PCI local bus clocks and 48 MHz clocks for Super I/O and USB interfaces. The device features four selectable PCI clocks, three LPC interface clocks, one fixed 66 MHz clock, and two reference clocks, making it versatile for various timing requirements. This component is packaged in a 28-pin SSOP format and is RoHS compliant. It operates at a voltage of 3.3 V ¬±5% and includes multiple power-down modes to minimize power consumption. Additionally, it has a low EMI enable pin to reduce electromagnetic interference on PCI clocks. The MK1491-09FLNTR is suitable for both industrial and commercial temperature ranges, with a specified operating temperature from 0 to +70¬8C.
