1.0 Features

2.0 Description

The FS6284 is a monolithic CMOS clock generator IC

designed to minimize cost and component count in digital

video/audio systems.

•

Dual phase-locked loop (PLL) device with three out-

put clock frequencies

•

3.3V supply voltage

All frequencies are ratiometrically derived from the crystal

oscillator frequency. The locking of all the output fre-

quencies together can eliminate unpredictable artifacts in

video systems and reduce electromagnetic interference

(EMI) due to frequency harmonic stacking.

Small circuit board footprint (8-pin 0.150″ SOIC)

Custom frequency selections available - contact your

local AMI Sales Representative for more information
