Description
The FMS6366 Filter Driver offers comprehensive filtering for set
top box or DVD applications. This part consists of triple 6th
order filters with selectable cutoffs for SD or HD. The filters are
in a 4:2:2 configuration such that Y1 switches between 8MHz
(SD) and 30MHz (HD). The Pb and Pr channels switch between
4MHz (SD) and 15MHz (HD). The required delay compensation
must be performed in the digital domain prior to filtering by the
FMS6366.
An additional S-video path is provided for SD signals. The Y2
and C signals are both filtered at 8MHz. A composite summer is
included to provide a composite output based on Y2 and C.
A 2:1 multiplexer is provided on each filter channel with separate
select lines for the YPbPr and YC signals.
All inputs accept DC-coupled ground referenced 1V_pp input signals.
The filter outputs include +6dB of gain resulting in a 2V_pp signal
into an AC-coupled dual video load (75Ω).
