NTE NTE1483

NTE1483
Integrated Circuit
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)
