NCS2554
Four-Channel Video Driver
with SD Reconstruction
Filters
The NCS2554 is a 4−channel high speed video driver with 6th order
Butterworth Reconstruction filters on each channel. A first set of
3−channel has Standard Definition (SD) filters, one per channel. A
fourth channel offers an extra filter driver for driving Cvbs−type video
signal. The NCS2554 is in fact a combination of a triple SD video
driver for YPbPr 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. 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.
