NTE1483
Integrated Circuit
Video IF System
Description:
The NTE1483 is a silicon monolithic integrated circuit in a 22鈥揕ead 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鈥搇evel detector, sound IF detector, AFC detector, IF AGC, RF AGC and
picture amplifier.
