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.
