Video IF System

Description:

The NTE1483 is a silicon monolithic integrated circuit in a 22–Lead DIP type package designed for

use in the PIF section in color TV receivers. As it contains a separate picture detector and sound IF

detector, this device offers low buzz characteristics. The NTE1483 has all functions including picture

IF amplifier (4th), picture low–level detector, sound IF detector, AFC detector, IF AGC, RF AGC and

picture amplifier.

Features:

D Low Buzz Characteristics for Audio Multiplex TV

D High Input Sensitivity

D Wide AGC Control Range

D Contains Differential Mode Input for use with SAW Filter

Absolute Maximum Ratings: (TA = +25°C unless otherwise specified)
