sentative for more information.

2.0 Description

The FS6322 is a ROM-based CMOS clock generator IC

designed to minimize cost and component count in a va-

riety of electronic systems.

Thr ee low-jitter phase-locked loops (PL Ls ) driv e u p to five

low-skew clock outputs to provide a high degree of flexi-

bility. The device is packaged in a 16-pin SOIC to mini-

mize board space.

High-resolution divider capability permits generation of

desired frequencies.
