NTE1413 & NTE1545

Integrated Circuit

Video IF Amplifier

Description:

The NTE1413 and NTE1545 are integrated circuits in a 16–Lead DIP type package designed for use
as video IF amplifiers for color and monochrome television receivers

Features:

D Available for Two Types of Tuners:

NPN Tuner (NTE1413)
FET Tuner (NTE1545)

D High Gain, Wide Band IF Amplifier: 50dB Typ. at 58MHz
D Gain Reduction with Excellent Stability: 55dB Typ. at 58MHz
D Excellent DG/DP Characteristics:

DG = 7% Typ.
DP = 3.5 deg Typ.

D Excellent S/N Characteristics due to Delayed 3 Stages AGC Action
D Negative video output signal
D Fast AGC Action due to Noise Inverter and Peak AGC
D Switch Off the Video Part with VTR SW
D Dual Differential AFT Output

Functions:

D Three Controlled IF Amplifier Stages
D Video Demodulator Controlled by Picture Carrier
D Black Noise and White Noise Inverter
D Peak AGC
D DC Amplifier for RF AGC Out
D Quadrature Detector for AFT
D DC Amplifier for AFT
