TDA4504B Datasheet - NXP

TDA4504B Small signal combination for multistandard colour TV

TDA4504B Having the capability to demodulate IF signals with either positive or negative-going video information, the TDA4504B (Fig.1) is contained within a 32 pin encapsulation. It includes a three-stage vision IF amplifier, mute circuit, AFC and AGC circuitry, fully synchronised horizontal and v.

TDA4504B Features

* Gain controlled vision IF amplifier

* Synchronous demodulator for negative and positive demodulation

* AGC detector operating on peak sync amplitude for negative demodulation and on peak white level for positive demodulation

* Tuner AGC

* AFC circuit with tw
