Overview
MK1432/MK1434 Green PC and Local Bus Clock Source Description The MK1432 and MK1434 are low cost, high performance triple clock synthesizers for green PC and local bus desktop and notebook applications.
Using analog Phase-Locked Loop (PLL) techniques, the devices accept a 14.
318 MHz crystal input to produce multiple output clocks up to 100 MHz.
They provide selectable 2XCPU and CPU, selectable local bus clock, ISA clock, and one fixed peripheral clock.
The chips support PCI and VL buses.
The fixed clock is either 24MHz or 40MHz.
The devices can operate at 5V or 3.
3V up to and including 80MHz on the 2XCPU clock.
The Power Saving pin causes the CPU clocks to smoothly transition to 33.
33 MHz fo...
