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
th
IF amplifier (4
picture amplifier.
