MK1491-14

The MK1491-14 is a low cost, low jitter, high performance clock synthesizer for OPTi's Firestar and Firestar+ chipsets for Pentium™ Processor-based mobile computer applications.

Using analog Phase-Locked Loop (PLL) techniques, MK1491-14 uses a 14.318 MHz crystal input to produce multiple output clocks up to 75 MHz. It provides selectable Host and PCI local bus clocks as well as selectable clocks for Super

I/O or Universal Serial Bus (USB). MK1491-14 has up to seven Host output clocks.

The chip of MK1491-14 has three different power down modes that reduce power on various clocks.
