NCS2584  
Four-Channel Video Driver  
with Load Detection and  
Signal Detection  
The NCS2584 is a 4channel high speed video driver with 6th order  
Butterworth Reconstruction filters on each channel. A first set of  
3channel has High Definition (HD) 34 MHz filters, one per channel.  
A fourth channel offers an extra driver for Cvbstype 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 BluRayplayers or Set Top Boxes to be in line with the  
restricting energy saving standards on standby modes.  
It is designed to be compatible with DigitaltoAnalog Converters  
(DAC) embedded in most video processors.  
All channels can accept DC or AC coupled signals. In case of  
ACcoupled 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.

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.

NCS2584  
APPLICATIONS INFORMATION  
The NCS2584 quad video driver has been optimized for  
implemented with stand alone op amps. An internal level  
shifter is employed shifting up the output voltage by adding  
an offset of 280 mV on the outputs. This prevents sync pulse  
clipping and allows DCcoupled output to the 150 W video  
Standard and High Definition video applications covering  
the requirements of the standards Composite video (Cvbs),  
Component Video (720p/1080i). The three HD channels  
have 34 MHz filters to cover high definitionlike video  
applications. A fourth channel implements one standard  
definition filter of 8 MHz bandwidth to drive the Cvbs  
signal.  
In the regular mode of operation, each channel provides  
an internal voltagetovoltage gain of 2 from input to  
output. This effectively reduces the number of external  
components required as compared to discrete approach  
th  
load. In addition, the NCS2584 integrates a 6 order  
Butterworth filter for each. This allows rejection of the  
aliases or unwanted over-sampling effects produced by the  
video DAC. Similarly for the case of DVD recorders which  
use a ADC, this antialiasing filter (reconstruction filter)  
will avoid picture quality issue and will help filtration of  
parasitic signals caused by EMI interference.

Figure 19. ACCoupled Configuration at the Input and Output  
A builtin diodelike clamp is used into the chip for each  
channel to support the ACcoupled mode of operation. The  
clamp is active when the input signal goes below 0 V.  
The builtin 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  
DCCoupled 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 ACcoupled when either the inputsignal  
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.  
coupling configuration ensures the maximum compatibility  
with all sorts of displays.  
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  
The output ACcoupling 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

capable of recognizing the load of the TV. With the  
The problems of field tilt effects on the video signal are  
also eliminated providing the best video quality with  
optimal dynamic or peaktopeak amplitude of the video  
signal allowing operating thanks to the builtin 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 ACcoupled configuration.  
ENERGY STAR® requirements, these innovative and  
patented features will perfectly fit with the power saving  
specifications.  
DCCoupled Output  
The outputs of the NCS2584 can be DCcoupled to a  
150 W load (Figure 20). This has the advantage of  
eliminating the ACcoupling 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.

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  
BlueRay players. This parameter is particularly important  
for video driver which usually constitutes the last stage in the  
video chain before the video output connector.
