Several versions have a Teletext decoder on board. The Teletext decoder has an internal RAM memory for 1or 10 page text. The ICs are intended to be used in economy television receivers with 90° and 110° picture tubes. The ICs have supply voltages of 8 V and 3.3 V and they are mounted in an S-DIP 64 envelope. The features are given in the following feature list. The differences between the various ICs are given in the table on page 4. FEATURES TV-signal processor Multi-standard vision IF circuit with alignment-free PLL demodulator Internal (switchable) time-constant for the IF-AGC circuit A choice can be made between versions with mono intercarrier sound FM demodulator and versions with QSS IF amplifier. In the QSS versions without East-West output an AM/FM mode can be activated. In that case both the QSS amplifier (for AM demodulation) and the FM demodulator are available. The mono interc...
