2 / 23 page  September 1990 2 Philips Semiconductors Preliminary specification Video signal processor for CD-video/laser vision TEA7650H FEATURES • Modulation Transfer Function correction (MTF) at signal input for both standards • HF drop out detector • Data slicer, data output for program information (IEC standards) • Separation of signals for Electronic Time Base Correction (ETBC) • Noise reduction with chrominance trap, noise level adjust point • Dynamic picture insertion and 6 dB video attenuation of main picture • Bandgap reference voltage output, suitable for CCD delay line GENERAL DESCRIPTION Bipolar IC for video signal processing used in CD-Video/LaserVision players. Standard PAL respectively NTSC output signal (CVBS). MTF amplifier. FM-demodulator followed by de-emphasis stage. PAL/NTSC switch for switching the MTF and de-emphasis. Drop out detector with drop out switch, also externally switchable. +5 volt supply, only 325 mW total power dissipation. QUICK REFERENCE DATA ORDERING AND PACKAGE INFORMATION Note 1.
