Integrated Circuit
TV Video IF Phase Locked Loop (PLL)
Synchronous Detector
Description:
The NTE843 is a linear IC synchronous detector employing a phase–locked oscillator to demodulate
the 45.75MHz video IF signals in color–TV receivers. The NTE843 features AFT voltage for DC con-
trol of the tuner; an adjustment for the zero–carrier DC level at the video output terminal; an amplifier
arrangement for inverting noise impulses toward the black level; and a separate output terminal (non–
inverting) for the sound IF.
The NTE843 is supplied in a 16–lead plastic “power–slab” dual–in–line package.
The “power–slab” package has an inherently low junction–to–case (slab) thermal resistance and
lends itself to a wide variety of heat–sink methods, depending on the application requirements.
Features:
PLL Carrier Oscillator with Wide Pull–In and Hold–In Range
Excellent Low–Level Detector Linearity
Noise Inversion at Video Output
Wide Range, Variable Zero–Carrier Level Adjustment
Automatic Fine Tuning (AFT) Detector
Separate Output for Sound Take–Off
12V Power Supply
