NCS2566 Datasheet, PDF (1/13 Pages) ON Semiconductor – Six-Channel Video Driver with Triple SD & Triple Selectable SD/HD Filters

NCS2566
Six-Channel Video Driver
with Triple SD & Triple
Selectable SD/HD Filters
The NCS2566 integrates reconstruction filters and video amplifiers.
It’s a combination of two 3−channel drivers − the first one capable to
deal with Standard Definition (SD) video signals and a second one
including selectable filters for either Standard or High Definition
(HD) video applications. The filters implemented are 6^th order
Butterworth Low Pass filters particularly effective for rejecting
unwanted high frequency components and assuring good linearity of
the phase change over frequency with well optimized group delays.
All channels can accept DC− or AC−coupled signals; when AC−
coupled the internal clamps are employed. The outputs can drive both
AC− and DC−coupled 150 W loads.
It is designed to be compatible with most Digital−to−Analog
Converters (DAC) embedded in video processors. To further reduce
power consumption, two enable pins are provided, one for each triple
driver. One pin allows selection of the filter frequency of the SD/HD
triple driver.
