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 post-
dividers. All frequencies are ratiometrically derived from
the crystal oscillator frequency. The locking of all the out-
put frequencies together can eliminate unpredictable ar-
tifacts in video systems and reduce electromagnetic in-
terference (EMI) due to frequency harmonic stacking.
