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

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.
