Description
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.
