Overview

www.DataSheet4U.com SM8721AB 3-PLL Multi-Output Clock Generator OVERVIEW The SM8721AB is a clock generator IC with 3 built-in PLLs.

It can simultaneously generate and output 3 clocks with different frequency derived from a single master clock.

The generated output clock frequency can be switched using control pins and one clock can be turned ON/OFF (CLK2).
