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 (4^th), 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: (T_A = +25°C unless otherwise specified)
