PRELIMINARY INFORMATION

• Tiny 28 pin SSOP (150 mil) package

• Quad one input to four output clock drivers

• Outputs are skew matched to within 250ps

• A, B, C and D banks matched to 250ps

• 3.3V±10% and/or 5V±10% supply voltage

• Clock speeds up to 200 MHz

• For tighter skew matching, more outputs, or

other speeds, consult ICS for other solutions

The MK74CB44 Buffalo™ is a monolithic

CMOS high speed clock driver. It consists of

four identical single input to four low-skew

output, non-inverting clock drivers. When

combined with ICS’s MK series of low jitter

clock synthesizers, the chips form an unequaled

high performance clocking scheme. This

monolithic solution can eliminate concern for

part-to-part skew matching. The MK74CB44 is

packaged in the tiny 28 pin SSOP, which uses the

same board space as the narrow 16 pin SOIC.
