TEA2000

      The TEA2000 is a monolithic integrated circuit,which encodes colodes information and provides composite video output for driving a VHF or UHF modulator.The TEA2000 has 5 features.The first one is european PAL and american NTSC/M standard selectable.The second one is internal generation of burst timing and PAL-switch-function.The third one is 6 bit binary TTL compatible input provides 64 different colours.The fourth one is TTL compatible colour blanking input.The fifth one is TTL compatible sync input.
      The TEA2000 PAL/NTSC colour encoder and video summer integrated circuit has an internal oscillator from which the (R-Y) and (B-Y) waveforms are generated.The TEA2000 accepts timing signals (composite sync,composite blanking) and a 6 bit binary coded input giving colour information.The input are organized as 2 bits per primary colour and gamma correction is applied to the resultant luminance and chrominance level .Each of the equally spaced intensity level (for each primary colour) is combined with those of the other primary colours.This produces 64 output colour comprising a wide range of saturated and desaturated colours,black,white and tow level of grey.The resultant output is a composite video signal compatible with the PAL and NTSC/M standards.
      The TEA2000 has some information about ratings,(limiting values in accordance with absolute maximum system).The supply voltage V11-9 is max. 13.2V.The voltages,pin 1,2,3,4,5,14,16,17,18 is max. V11-9 V.The storage temperature is -20 to +125 .The operating ambient temperature is 0 to +70 .
      At present there is not too much information about this model.If you are willing to find more  about the TEA2000, please pay attention to our web! We will promptly update the relevant  information.
