     X  T 'XDO 3// &ORFN *HQHUDWRU ,& $GYDQFH ,QIRUPDWLRQ )6 March 2000 1.0 • • • • Features 2.0 Description Dual phase-locked loop (PLL) device with three output clock frequencies 3.3V supply voltage Small circuit board footprint (8-pin 0.150″ SOIC) Custom frequency selections available - contact your local AMI Sales Representative for more information The FS6284 is a monolithic CMOS clock generator IC designed to minimize cost and component count in digital video/audio systems. All frequencies are ratiometrically derived from the crystal oscillator frequency. The locking of all the output frequencies together can eliminate unpredictable artifacts in video systems and reduce electromagnetic interference (EMI) due to frequency harmonic stacking.
