MK74CB214

MK74CB214 Dual 1 to 7 Buffalo™ Clock Driver Description 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 lowskew 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 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. Features 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 Family of MicroClock Parts The MK74CB214 Buffalo™ is designed to be used with MicroClock’s clock synthesizer ...
