INTEGRATED CIRCUITS DATA SHEET TDA4504B Small signal combination for multistandard colour TV Product specification File under Integrated Circuits, IC02 February 1992 Philips Semiconductors Product specification Small signal combination for multistandard colour TV 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 two control polarities and on/off-switch · Video preamplifier · Video switch to select either the internal video signal or an external video signal · Horizontal oscillator and synchronization circuit with two control loops · Vertical synchronization (divider system), ramp generator and driver with automatic amplitude adjustment for 50 and 60 Hz · Transmitter identification (mute) · Sandcastle pulse generation · VCR/auto VCR switch · Start-up circuit · Vertical guard GENERAL DESCRIPTION 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 vertical timebases with drive circuits and integral three-level sandcastle pulse generator. A functional colour tv receiver can thus be realized with the addition of a tuner, audio demodulator and amplifier, chroma decoder and respective line and field deflection circuitry.
