MK1432 Overview
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.
Key Features
- Packaged in 16 pin narrow (150 mil) SOIC
- Supports all Pentium ™ Processor timing specs
- Supports synchronous and asynchronous local bus
- Selectable local bus frequencies of 25, 33, or 50MHz
- SCSI or VL bus 40MHz clock on MK1434
- Floppy or super I/O clock on MK1432
- Single Power Saving pin switches to low power mode (for 486 and Pentium)
- 5V or 3.3V (up to 80MHz) operation
- Smooth transitions for Pentium and 486 based Green PC
- Low skew (<250ps) Pentium compatible 2X and 1X outputs
