Functional Description
ASM5P2309A is a versatile, 3.3V zero-delay buffer
designed to distribute high-speed clocks. It accepts one
reference input and drives out nine low-skew clocks. It is
available in a 16-pin package. The ASM5P2305A is the
eight-pin version of the ASM5P2309A. It accepts one
reference input and drives out five low-skew clocks.
The -1H version of the ASM5P23XXA operates at up to
The ASM5P2309A and the ASM5P2305A are available in
two different configurations, as shown in the ordering
information table. The ASM5P2305A-1/ ASM5P2309A-1 is
the base part. The ASM5P2305A-1H/ ASM5P2309A-1H is
the high drive version of the -1 and its rise and fall times
are much faster than -1 part.

Notes:
1. This output is driven and has an internal feedback for the PLL. The load on this output can be adjusted to change the skew between the reference and the
output.
Zero Delay and Skew Control
For applications requiring zero input-output delay, all
All outputs should be uniformly loaded to achieve Zero
Delay between input and output. Since the CLKOUT pin is
the internal feedback to the PLL, its relative loading can
adjust the input-output delay.
outputs, including CLKOUT, must be equally loaded. Even
if CLKOUT is not used, it must have a capacitive load equal
to that on other outputs, for obtaining zero-input-output
delay.
