2.0 Description
The FS6183 is a monolithic CMOS clock generator IC
designed to minimize cost and component count in digital
video/audio systems.
A high-resolution phase-locked loop generates three out-
put clocks (CLKA, CLKB, & CLKC) through an array of
post-dividers. All frequencies are ratiometrically derived
from the crystal frequency. The locking of all the output
frequencies together can eliminate unpredictable artifacts
in video systems.

3.0 Functional Block Description
3.1
Phase-Locked Loop (PLL)
The on-chip PLLs are a standard frequency- and phase-
locked loop architecture. The PLL multiplies the reference
oscillator to the desired frequency by a ratio of integers.
The frequency multiplication is exact with a zero synthe-
sis error.
3.2 Crystal
Oscillator
The oscillator operates the crystal resonator in the paral-
lel-resonant mode.
The FS6183-03 has a special high transconductance
crystal oscillator to insure start-up under all conditions
when used in the external varactor-based VCXO circuit
used in the GI DCT-2000.
