... Good Pulse Response • Excellent Intermodulation Figures 1. Description The TDA4470 is an integrated bipolar circuit for multistandard video/sound IF (VIF/SIF) signal processing in TV/VCR and multimedia applications. The circuit pro- cesses all TV video IF signals with negative modulation (e.g., B/G standard), and the FM/NICAM sound IF signals. ...

... The optional potentiometer at pin 26 allows an offset compensation of the VCO phase for improved sound quality (fine adjustment). Without a potentiometer (open circuit at pin 26), this offset compensation is not active. The oscillator signal passes a phase shifter and supplies the in-phase signal (0°) and the quadrature signal (90°) of the generated picture carrier. 4803C–TVVCR–10/05 TDA4470 3 ...

... With a control voltage at pin 14 the VCO frequency can be switched in order to set required L’ value (L’ standard). Also a fine adjustment of the L’-VCO center frequency is possible via a potentiometer. The L' switch is only active for positively modulated video IF-signals (standard switch in L mode). TDA4470 ...

... IF circuit. With an external switching voltage at pin the IF amplifiers are switched off and all signal output levels at pins 12, 24, and 25 are according to the internal DC voltage. 2.12 Internal Voltage Stabilizer The internal bandgap reference ensures constant performance independent of supply voltage and temperature. 4803C–TVVCR–10/05 TDA4470 5 ...
