Description
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,
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.
