DUAL 1 TO 8 BUFFALO™ CLOCK DRIVER
DATASHEET
MK74CB218
Description
The MK74CB218 Buffalo™ is a monolithic
CMOS high speed clock driver. It consists of two identical single input to eight low-skew output, non-inverting clock drivers. This eliminates concerns of part to part matching in many systems. The MK74CB218 is packaged in the tiny 28-pin SSOP, which uses the same board space as the narrow 16-pin SOIC. The inputs can be connected together for a 1 to 16 fanout buffer.
A quad 1 to 4, and PECL versions, are also available. Consult IDT for more details.
The MK74CB218 can also act as a
voltage translator, since it is possible to run the inputs at 3.3 V and the outputs at 2.5 V.
Features
Packaged as 28-pin SSOP (150 mil body) Pb (lead) free package, RoHS compliant Dual one input to eight output clock drivers Outputs are skew matched to within 250 ps A outputs and B outputs matched to 250 ps 2.5 V or 3.3 V output
voltages Output Enable tri-states each bank of eight Clock speeds up to 200 MHz
Family of IDT Parts
The MK74CB218 Buffalo™ is designed to be used with IDT’s clock synthesizer devices. The inputs of the Buffalo are matched to the outputs of IDT clock synthesizers. Consult IDT for applications support.
Not recommended for new designs. See the MK74CB218B for new designs.
