TEA7650H
Overview
- 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 QUICK REFERENCE DATA SYMBOL VP IP Vi (p-p) Vo (p-p) V29 Vi (p-p) Vi (p-p) Vo (p-p) V42 Vo (p-p) total supply current FM input signal at pin 7 (peak-to-peak value) CVBS output signal for CCDs (peak sync - peak white, pin 29) black level voltage (pin 29) delayed CVBS input signal for drop out path at pin 27 (peak-to-peak value) delayed CVBS input signal at pin 31 from ETBC path (peak-to-peak value) main CVBS output signal at pin 42 (peak-to-peak value) black level voltage (pin 42) chrominance output signals at pins 44, 48 (peak-to-peak value) PAL (burst) NTSC (burst) Vref reference output voltage (pin 41) - - - 760 725 1.6 PARAMETER supply voltage (pins 12, 30, 47) MIN. - - 50 - - - - - - GENERAL DESCRIPTION TEA7650H 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.
