PRELIMINARY INFORMATION
MK74CB44
Quad 1 to 4 Buffalo™ Clock Driver
Description
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.
Features
• 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
Family of ICS Parts
The MK74CB44 Buffalo™ is designed to be used
with ICS’s clock synthesizer devices. The inputs
of the Buffalo are matched to the outputs of ICS
clock synthesizers. Consult ICS for applications
support.
