MK74CB163

MK74CB163 1 to 16 PECL to CMOS Buffalo™ Clock Driver Description The MK74CB163 Buffalo™ is a monolithic CMOS high speed clock driver. It consists of a PECL input to sixteen low-skew output, noninverting clock drivers. This monolithic solution eliminates any concern for part-to-part skew matching. The MK74CB163 is packaged in the tiny 28 pin SSOP, which uses the same board space as the narrow 16 pin SOIC. PRELIMINARY INFORMATION Features Tiny 28 pin SSOP (150 mil) package One input to sixteen output clock drivers Outputs are skew matched to within 250ps 3.3 V±10% supply voltage Clock speeds up to 156 MHz 2 Output Enables allow configuration as 1 to 6, 1 to 10, or 1 to 16 buffers. Converts PECL input to CMOS level outputs Family of ICS Parts The MK74CB163 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.
