NTSC PAL NTSC multi standard television receivers These IC 5 are nearly pin compatible with TDA837X TV processors but have higher degree of integration because the delay line TDA4665 function and the SECAM decoder have been integrated In addition to these functions some additional features have been added like Continuous Cathode Calibration 2 point black current loop which results in an accurate biasing of the 3 guns adjustable luminance delay time blue stretching and dynamic skin tone control Features Vision IF circuit with PLL demodulator Alignment free multi standard FM sound demodulator 4 5 MHz to 6 5 MHz Audio switch Flexible source selection with CVBS switch and Y CVBS C input so that a comb filter can be applied Integrated chrominance trap circuit Integrated luminance delay line Asymmetrical peaking in the luminance channel with a noise coring function Black stretching of non standard CVBS or luminance signals Integrated chroma band pass filter with switchable center frequency Blue stretch circuit which offsets colours near white towards blue RGB control circuit with Continuous Cathode Calibration and white point adjustment Linear RGB inputs and fast blanking Possibility to insert a blue black option when no video signal is available Horizontal synchronisation with two control loops and alignment free horizontal oscillator Vertical count down circuit Vertical driver optimised for DC couple

Its frequency is divided by 2 to lock the first control loop to the incoming signal The time constant of the loop can be forced by the fast or slow If required the IC can select the time constant depending on the noise content of the incoming video signal To protect the horizontal output transistor the horizontal drive is immediately switched off when a power on reset is detected The drive signal is switched on again when the normal switch on procedure is followed Via the adjustments can be made of the horizontal and vertical geometry The vertical sawtooth generator drives the vertical output drive circuit which has a differrential output current For the EW drive a single ended current output is available When the horizontal scan is reduced to display 4 3 pictures on a 16 9 picture tube an accurate video blanking can be switched on to obtain well defined edges on the screen Overvoltage conditions can be detected via the tracking pin When an overvoltage condition is detected the horizontal output drive signal will be switched off via the slow stop procedure but it is also possible that the drive is not switched off and that just a protection indication is given in the I C bus output byte The choice is made via the input bit PRD 2 5 Chroma and Luminance processing The circuits contain a chroma bandpass and trap circuit The filters are realised by means of gyrator circuits and they are automatic
