2.0 Description

The FS6322 is a ROM-b ased CMOS clock generator IC designed to minimize cost and com ponent count in a variety of electronic systems.

Three low-jitter phase-loc ked loops (PLLs) driv e u p to f iv e low-skew clock outpu ts to provide a high de gree of flexibility. The device is packaged i n a 16-pin SOIC to minimize board space.

High-resolution divider capability permits generation of desired frequencies.
