Stresses above the ratings listed below can cause permanent damage to the MK1491-06. These ratings, which are standard values for ICS commercially rated parts, are stress ratings only. Functional operation of the device at these or any other conditions above those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods can affect product reliability. Electrical parameters are guaranteed only over the recommended operating temperature range.

The MK1491-06 is a low-cost, low-jitter, high-performance clock synthesizer for AMD's Geode-based computer and portable appliance applications. Using patented analog Phased-Locked Loop (PLL) techniques, MK1491-06 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.

MK1491-06 has multiple power-down modes to reduce power consumption.
