2.0 Description

The FS6282 is a monolithic CMOS clock generator IC

designed to m inim ize cost a nd com ponen t count in digi tal

video/audio systems.

Two high-resolution phase-locked loops generate two

output clock s (C LKA and CL KB) through a n ar r ay of post-

dividers. All frequencies are ratiometrically derived from

the cr ystal oscill ator frequenc y. The lock ing of all the out-

put frequencies together can eliminate unpredictable ar-

tifacts in video systems and reduce electromagnetic in-

terfer ence (EMI) due to fr eque ncy harmonic stacking.

Table 3: Absolute Maximum Ratings

Stresses above those listed under Absolute Maximum Ratings may cause permanent damage to the device. These conditions represent a stress rating only, and functional operation of the device at

these or any other conditions above the operational limits noted in this specification is not implied. Exposure to maximum rating conditions for extended conditions may affect device performance,

functionality, and reliability.
