APPLICATIONS INFORMATION
The NCS2561 is a single video driver optimized for
portable applications with low power consumption in a
space saving SC88 package. It includes sag correction
circuitry allowing significant reduction of the ACcoupled
output capacitor.
Internal Level Shift
The input common mode voltage range (see
specifications VIN) of the NCS2561 includes the lower rail
(GND) and extends to VCC 1.5V on a power supply range
of 2.7 V to 3.3 V. Many video processors operate with a
supply ranging from 0 V to a positive supply (typically
3.3 V), so the lowest voltage of the video signal provided by
the DAC is 0 V. Although a 0 V (GND) signal is within the
input commonmode range of the NCS2561, the output
signal will be limited, specifically at the lower rail. Op amps
use transistors with saturation voltage (Vsat) higher than
0 V. If the lowest level of the input voltage is lower than Vsat
the signal will be clipped at the output.
To ensure the output signal is not clipped due to the lower
rail limit, the NCS2561 has builtin level shift circuitry. The
role of this circuitry is to avoid clipping of the sync signal at
the output by shifting up the video signal by about 60 mV.
The level shift circuitry level shifts the sync signal above the
internal op amp transistor saturation limit. This function is
particularly useful when the video signal is DCcoupled at
the output.
Builtin 2Pole Reconstruction Filter
The NCS2561 has a 2pole reconstruction filter with a
3 dB cutoff frequency at 8 MHz. The filter serves as an
antialias filter removing the unwanted oversampling
effects produced by the video DAC. The 27 MHz
oversampling frequency from the video DAC is attenuated
by 22 dB typical. In order to improve the stopband
attenuation a small capacitor (Cs) of a few tenths pico Farads
can be added in parallel with the source resistor (Rs) (See
Figure 10).

Shutdown Mode
If the Enable pin is left open by default the circuit will be
enabled. The Enable pin offers a shutdown function, so the
NCS2561 can consequently be disabled when not used. This
is particularly important for digital still cameras or cell
phones with camera having a video output feature. Indeed
this video output is not permanently used and actually used
in very specific period of time when pictures or small movies
want to be displayed on a bigger screen. The device’s
quiescent current drops typically down to 2.7
mA when the
device is in the shutdown mode.
