2.0 Description

The FS6282 is a monolithic CMOS clock generator IC designed to minim ize cost a nd com ponen t coun t i n d igital video/audio systems.

Two high-resolution phase-locked loops generate two output clocks (CLKA and CL KB) t hr oug h a n arr ay of postdividers. All frequencies are ratiometrically derived from the crystal oscillator frequenc y. The lock ing of all th e output frequencies toget her can eliminate unpredicta ble artifacts in video systems and reduce electromagnetic interference (EMI) due to frequenc y harm onic 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.
