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). The master clock can be selected from a low-cost 14.31818MHz or small 28.636363MHz crystal. The device is available in compact 20-pin QFN packages, making it ideal for portable digital still cameras and other applications which require multiple clocks.
