Dual PLL Clock Generator IC October 1999 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 Figure 1: Pin Configuration CLKA VSS XIN XOUT 1 8 The FS6282 is a monolithic CMOS clock generator IC designed to minimize cost and component count in digital video/audio systems. Two high-resolution phase-locked loops generate two output clocks (CLKA and CLKB) through an array of postdividers. 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.
