NCS2563 http://onsemi.com 7 applications information the NCS2563 triple video driver has been optimized for high definition video applications covering the requirements of the standards 720p, 1080i and related (rgb). all the 3 channels feature the same specifications and similar behaviors guaranteed by a high channel-to-channel crosstalk isolation (down to 60 db at 1 mhz). each channel provides an internal voltage-to-voltage gain of 2 from its input to its output reducing by the way the number of external components usually needed in the case of some discrete approaches (using stand-alone op amps). an internal level shifter is employed shifting up the output voltage by adding an offset of about 280 mv. this avoids sync pulse clipping and allows dc-coupled output to the 150 video load. in addition, the NCS2563 integrates a 6 th order butterworth filter per channel with a 3 db frequency bandwidth of 30 mhz. this allows rejecting out the aliases or unwanted over-sampling effects produced by the video dac. it works the same way for dvd recorders using adc, this anti-aliasing filter (reconstruction filter) will avoid picture quality issue and will help also to filter out parasitic signals caused by emi interference. a built-in diode-like clamp is used into the chip for each channel to support ac-coupled mode of operation. the clamp is active when the input signal goes below 0 v. figure 12. ac-coupled inputs and outputs dac 0v 1v 2.28v 0.28v 75 75 75 1v pp 0.7v pp z o = 75 z o = 75 z o = 75 75 75 75 220 f 220 f 220 f out1 out2 out3 2.28v 0.28v 0.1 f 0.1 f 0.1 f r s r s r s in1 in2 in3 y, r', g', b' pb, pr clamp clamp clamp figure 12 shows an example for which the external video source coming from the dac is ac-coupled at the input and output. but thanks to the built-in transparent clamp and level shifter the device can operate in dif ferent configuration modes depending essentially on the dac output signal level high and low and how it fits the input common mode voltage of the video driver. when the configuration is dc-coupled at the inputs and outputs the 0.1 f and 220 f coupling capacitors are no longer used, the clamps are in that case inactive; this configuration has the big advantage of being relatively low cost with the use of less external components. the input is ac-coupled if the input-signal amplitude goes over the range 0 v to 1.4 v or if the video source requires a coupling. in some circumstances it may be necessary to auto-bias signals by the addition of a pull-up and pull-down resistor or only pullup resistor (typical 7.5 m combined with the internal 800 k pulldown) making the clamp inactive. the output ac-coupling configuration has the advantage of eliminating dc ground loop with the drawback of making the device more sensitive to video line or field tilt issues in the case of a too low output coupling capacitor. in some cases it may be necessary to increase the nominal 220 f capacitor value.
