NCS2584
Four-Channel Video Driver
with Load Detection and
Signal Detection
The NCS2584 is a 4−channel high speed video driver with 6th order
Butterworth Reconstruction filters on each channel. A first set of
3−channel has High Definition (HD) 34 MHz filters, one per channel.
A fourth channel offers an extra driver for Cvbs−type video signal
with an 8 MHz filter. The NCS2584 is in fact a combination of a triple
HD video driver plus a single Cvbs video driver.
In addition, this four channel video driver integrates an auto
shutdown function in order to detect the moment when the DAC is
turned on or off. It also embeds a load detection to lower the power
consumption when the TV is unplugged. To further reduce the layout
and software complexity, the NCS2584 will automatically turn off
without any external command. These features help significantly the
systems like Blu−Ray™ players or Set Top Boxes to be in line with the
restricting energy saving standards on standby modes.
It is designed to be compatible with Digital−to−Analog Converters
(DAC) embedded in most video processors.
All channels can accept DC or AC coupled signals. In case of
AC−coupled inputs, the internal clamps are enabled. The outputs can
drive both AC and DC coupled 150 W loads but also two loads of
150 W in parallel.

Stresses exceeding Maximum Ratings may damage the device. Maximum Ratings are stress ratings only. Functional operation above the
Recommended Operating Conditions is not implied. Extended exposure to stresses above the Recommended Operating Conditions may affect
device reliability.
1. 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.

coupling configuration ensures the maximum compatibility
with all sorts of displays.
A built−in diode−like clamp is used into the chip for each
channel to support the AC−coupled mode of operation. The
clamp is active when the input signal goes below 0 V.
The built−in clamp and level shifter allow the device to
operate in different configuration modes depending on the
DAC output signal level and 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, and the
clamps are in that case inactive; this configuration provides
a low cost solution which can be implemented with few
external components (Figure 19). It also require the user the
ensure the input voltage range stays within 0 V to 1.4 V.
The input is AC−coupled when either the input−signal
amplitude goes over the range 0 V to 1.4 V. Activating the
clamp becomes mandatory and the use of the 0.1 mF is
necessary.
The output AC−coupling configuration is advantageous
for eliminating DC ground loop with the drawback of
making the device more sensitive to video line or field tilt
issues. In some cases, it may be necessary to increase the
nominal 220 mF capacitor value. Meanwhile the AC
Shutdown Mode
The NCS2584 integrates a shutdown mode function
which allows the device to detect when the video DAC turns
on or off. When the video DACs turn ON, the video drivers
will turn ON on as soon as they detect a stimulus. Meanwhile
if any glitch happens on the input line, embedded filters will
ignore them to prevent undesired behavior. In this case, the
turn on time is typically around 2 ms to avoid any missing
information. When the chipset turns on, it has to go through
a boot sequence which is significantly longer than this turn
on time. Then, the video drivers will go to a shutdown mode
in order to significantly lower the power consumption only
when no more stimulus is detected from the video DACs. In
addition, the NCS2584 integrates also a load detection
function. It only occurs on the Cvbs which is an independent
signal and the fist HD channel which contains the
synchronization information. It identify when the user plugs
the analog video lines of the TV or not. If these are not
plugged, then the device goes into a standby mode to reduce
the power consumption of the system. The device is in fact

optimal dynamic or peak−to−peak amplitude of the video
signal allowing operating thanks to the built−in level shifter
without risk of signal clipping. In this coupling
configuration the average output voltage is higher than 0 V
and the power consumption can be a little higher than with
an AC−coupled configuration.
capable of recognizing the load of the TV. With the
ENERGY STAR® requirements, these innovative and
patented features will perfectly fit with the power saving
specifications.
DC−Coupled Output
The outputs of the NCS2584 can be DC−coupled to a
150 W load (Figure 20). This has the advantage of
eliminating the AC−coupling capacitors at the output by
reducing the number of external components and saving
space on the board. This can be a key advantage for some
applications with limited space.

NCS2584
Video Driving Capability
ESD Protection
With an output current capability of 40 mA the NCS2584
was designed to be able to drive at least two video display
loads in parallel. This type of application is illustrated in
Figure 23. Figure 24 (multiburst) and Figure 25 (linearity)
show that the video signal can efficiently drive a 75 W
equivalent load and not degrade the video performance.
All the device pins are protected against electrostatic
discharge at a level of 6 kV following HBM JEDEC
standards. This feature has been considered with a particular
attention with ESD structure able to sustain the typical
values requested by the systems like Set Top Boxes or
Blue−Ray players. This parameter is particularly important
for video driver which usually constitutes the last stage in the
video chain before the video output connector.
