The input and output propagation delay is guaranteed to be less than 250 pS, and the output to output skew is Functional Description guaranteed to be less than 250 pS. ASM5P23S09A is a versatile, 3.3V zero-delay buffer designed to distribute high-speed clocks with Spread Spectrum capability. It is available in a 16-pin package. The ASM5P23S05A is the eight-pin version of the ASM5P23S09A. It accepts one reference input and drives The ASM5P23S09A and the ASM5P23S05A are available in two different configurations, as shown in the ordering information table. The ASM5P23SxxA-1 is the base part. The ASM5P23SxxA-1H is the high drive version of the -1 part and its rise and fall times are much faster than -1 part.
