NCS2564
Four-Channel Video Driver
with Selectable SD / HD
Reconstruction Filters
The NCS2564 is a 4−channel high speed video driver with 6th order
Butterworth Reconstruction filters on each channel. A first set of
3−channel has selectable Standard Definition (SD) / High Definition
(HD) filters, one per channel. A fourth channel offers an extra filter
driver for driving CVBS−type video signal. The NCS2564 is in fact a
combination of a triple SD/HD video driver plus a single CVBS video
driver.
It is designed to be compatible with Digital−to−Analog Converters
(DAC) embedded in most video processors.
To further reduce power consumption, 2 enable pins are provided
one for the triple driver and another one for the single driver. One pin
allows selecting the filter frequency of the triple driver. 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.

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 (T
J
) is not exceeded.

TEMPERATURE (°C)
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.
