Recommended Operating Conditions is not implied. 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.
Maximum Power Dissipation
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.

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 W video load. 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.

Clamp Clamp Clamp
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.
