NCS2564
Four-Channel Video Driver
with Selectable SD / HD
www.dataRsheeet4cu.coomnstruction 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.
