MK1432/MK1434  
Green PC and Local Bus Clock Source  
Features  
Description  
The MK1432 and MK1434 are low cost, high  
• Packaged in 16 pin narrow (150 mil) SOIC  
• Supports all PentiumProcessor 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)  
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.  
• 5V or 3.3V (up to 80MHz) operation  
• Smooth transitions for Pentium and 486 based  
Green PC  
The Power Saving pin causes the CPU clocks to  
smoothly transition to 33.33 MHz for Pentiums, and  
16.67 MHz for 486DX4. In addition, a single pin can be  
made to slow DX2s to 8 MHz.  
• Low skew (<250ps) Pentium compatible  
2X and 1X outputs  
• Duty cycle of 45/55 up to 100 MHz  
• 25mA output drive capability at TTL levels  
• Compatible with all popular microprocessors  
• Packaged in 16 pin narrow SOIC  
• For Early Clock support, consult MicroClock
