MK74CB214  
Dual 1 to 7 Buffalo™ Clock Driver  
Description  
Features  
The MK74CB214 Buffalo™ is a monolithic  
CMOS high speed clock driver which is ideal for  
Pentium, 486, and RISC processor systems. It  
consists of two identical single input to seven low-  
skew output, non-inverting clock drivers. When  
combined with MicroClock’s MK14xx series of  
low jitter clock synthesizers, the two chips form an  
unequaled high performance clocking scheme for  
new processors. This is the only solution on the  
market that meets Intel’s specs for skew and jitter.  
Many new Pentium systems require up to seven  
outputs each of two low-skew clocks. This  
• Tiny 20 pin SSOP (150 mil) package  
• Dual one input to seven output clock drivers  
• Outputs are skew matched to within 250ps  
• A outputs and B outputs matched to 500ps  
• 3.3V±10% and/or 5V±10% supply voltage  
• Each set of seven clock drivers can run from  
different supply voltages, making it possible to  
have 3.3V and 5V amplitude clock outputs from  
the same chip  
• Clock speeds up to 66.67 MHz  
monolithic solution eliminates any concern for  
part-to-part skew matching. The MK74CB214 is  
packaged in the tiny 20 pin SSOP, which uses the  
same board space as the narrow 14 pin SOIC. An  
added feature of the chip is the ability to produce  
both 3.3V and 5V amplitude clocks by connecting  
different voltages to VDDA and VDDB. See  
MAN03 for dual voltage operation.  
Family of MicroClock Parts  
The MK74CB214 Buffalo™ is designed to be  
used with MicroClock’s clock synthesizer devices,  
which will produce the CPU, memory, and local  
bus clocks. The inputs of the Buffalo are matched  
to the outputs of MicroClock clock synthesizers.  
Consult MicroClock for applications support.
