VF8418
Preliminary
TRIPLE VIDEO DRIVER
WITH SELECTABLE
HD/SD VIDEO FILTERS
FOR RGB OR YUV
SIGNALS
CMOS IC
DESCRIPTION
The U TC VF8418 consists of a triple 6 th order filter w ith
selectable 30MHz or 8.0M Hz frequ encies. The triple fi lters ar e
intended f or either Y UV or RGB sign als. There is a 2-to-1
multiplexer in each filter channel. All channels accept DC coupled
ground-referenced 1V signals.
The filters provide 2V pp sig nals i nto AC coupl ed termi nated
loads. T he lo w-pass filters ar e po wered by 3.3V an d the o utputs
by 5.0V.
The U TC VF8418 offers c omprehensive filtering for c able
set-top bo xes, satellite set-to p bo xes, HDT V, video o n d emand
(VOD), personal video recorders, or DVD applications.
FEATURES
* Three video anti-aliasing or reconstruction filters
* 2:1 Mux inputs for multiple RGB/YUV inputs
* Selectable 8MHz or 30MHz 6th order filters for SD/HD
applications
* DC coupled input, AC coupled output
* Drives single, +6dB output AC coupled 150Ω loads
* 0.6% differential gain with 0.15° differential phase
* 36dB/octave roll-off on all channels
