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.
