GENERAL DESCRIPTION
The TDA2549 is a complete i.f. circuit with a.f.c., a.g.c., demodulation and video preamplification facilities for multistandard television receivers. It is capable of handling positively and negatively modulated video signals in both colour and black/white receivers.
Features
? Gain-controlled wide-band amplifier providing complete i.f. gain
? Synchronous demodulator for positive and negative modulation
? Video preamplifier with noise protection for negative modulation
? Auxiliary video input and output (75 ?)
? Video switch to select between auxiliary video input signal and demodulated video signal
? A.F.C. circuit with on/off switch and inverter switch
? A.G.C. circuit for positive modulation (mean level) and negative modulation (noise gate)
? A.G.C. output for controlling MOSFET tuners
