Extended exposure to stresses above the Recommended Operating Conditions may affect device reliability. 4. Power dissipation must be considered to ensure maximum junction temperature (TJ) is not exceeded. 1800 The maximum power that can be safely dissipated is limited by the associated rise in junction temperature. For the plastic packages, the maximum safe junction temperature is 150°C. If the maximum is exceeded momentarily, proper circuit operation will be restored as soon as the die temperature is reduced. Leaving the device in the “overheated” condition for an extended period can result in device burnout. To ensure proper operation, it is important to observe the derating curves. 1600 POWER DISSIPATION (mV) Maximum Power Dissipation 1400 1200 1000 800 600 400 200 0 −40 −30−20−10 0 10 20 30 40 50 60 70 80 90100 TEMPERATURE (°C) Figure 2.

In addition, the NCS2563 integrates a 6th 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. 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 2.28V 1V Y, R’, G’, B’ 1VPP 0V 0.1mF IN1 Clamp 0.28V 220mF 75W OUT1 0.1mF IN2 DAC Clamp RS 220mF OUT2 Clamp IN3 220mF OUT3 RS 75W ZO = 75W 75W ZO = 75W 75W 75W RS 0.1mF ZO = 75W 75W 2.28V Pb, Pr 0.28V 0.7VPP Figure 11. AC−Coupled Inputs and Outputs Figure 11 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 different 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 mF and 220 mF 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 MW combined with the internal 800 kW 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 mF capacitor value. http://onsemi.com 7 NCS2563 DVD Player or STB +5 V 0.1 mF 1 R/Pr 10 mF IN1 OUT1 8 Video SOC 2 IN2 OUT2 NCS2563 RS 3 B/Pd RS R/Pr 75 W RS G/Y 75 W 220 mF 75 W Video Cables IN3 OUT3 7 75 W 220 mF 75 W Video Cables G/Y 75 W 6 75 W 220 mF 75 W Video Cables B/Pd 75 W 4 VCC GND 5 DAC Load Resistors AC−Coupling Caps are Optional Figure 12.
