GENERAL DESCRIPTION
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.
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
