NTE15003
Integrated Circuit
PIF Subsytem for TV Receiver
Description:
The NTE15003 is a picture IF subsystem that provides 3stage IF amplifier, Video Detector, black and
white noise inverting circuits and AFT detector for a TV receiver.
The NTE15003 also provides internal fast response AGC with dual time constants for the IF amplifier
stages and delayed AGC for an external RF amplifier stage. It is designed for FET top frontend
(reverse AGC).
