The FS6282 is a monolithic CMOS clock generator IC designed to minimize cost and ponent 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.
