2.0 Description

The FS6244 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 three

output clocks through an array of post-dividers. All fre-

quencies are ratiometrically derived from the crystal os-

cillator frequency. The locking of all the output frequen-

cies together can eliminate unpredictable artifacts in

video systems and reduce electromagnetic interference

(EMI) due to frequency harmonic stacking.

3.0 Functional Bl ock Descripti on

3.1 Phase-Locked Loop (PLL)

The on-chip PLLs are a standard frequency- and phase-

lock ed loop archi tec tur e. The PLL multip lies t he r ef er ence

oscillator to the desired frequency by a ratio of integers.

The frequency multiplication is exact with a zero synthe-

sis error unless otherwise indicated in the frequency ta-

ble.

3.2 Crystal Oscillator

The Crystal Oscillator provides a stable, low-jitter fre-

quenc y reference f or the rest of the FS62 44 system com -

ponents. L oading c apacitanc e for the cr ystal is inter nal to

the FS6244. No external components (other than the

resonator itself) are required for operation of the crystal

oscillator.
