The ASM5P2309A / ASM5P2305A 3.3V Zero Delay Buffer is a high performance clock buffer used to distribute high speed clocks on CPU and PCI busses. It has zero input - output propagation delay, multiple low-jitter outputs and less than 250ps output - output jitter.
This document describes the ASM5P2309A and ASM5P2305A, which are 3.3V zero-delay buffers designed to distribute high-speed clocks with minimal propagation delay. The ASM5P2309A accepts one reference input and drives nine low-skew outputs, while the ASM5P2305A drives five outputs. Both devices utilize an on-chip PLL that locks to an input clock on the REF pin.
