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.
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.
