Overview
TELEFUNKEN Semiconductors
TDA4439
Video IF Amplifier for Multistandard TV and VTR
Technology: Bipolar Features
D Standard B/G-L suitable, processes negatively and
positively modulated IF-signals with equal polarity of the output signal
D High input sensitivity D Fast AGC by controlled discharge of the AGC capacitor
Standard L mode: AGC acting on peak white level, capacitor discharge control by averaged video signal Standard B/G: AGC acting on the sync.
