NTE843
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:
D PLL Carrier Oscillator with Wide Pull–In and Hold–In Range
D Excellent Low–Level Detector Linearity
D Noise Inversion at Video Output
D Wide Range, Variable Zero–Carrier Level Adjustment
D Automatic Fine Tuning (AFT) Detector
D Separate Output for Sound Take–Off
D 12V Power Supply
