Functional Block Diagram
Description
The FMS6366 Filter Driver offers comprehensive ï¬ltering
for set top box or DVD applications. This part consists of
triple 6th order ï¬lters with selectable cutoffs for SD or HD.
The ï¬lters are in a 4:2:2 conï¬guration 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 ï¬ltering by the FMS6366.
An additional S-video path is provided for SD signals. The
Y2 and C signals are both ï¬ltered 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 ï¬lter channel with
separate select lines for the YPbPr and YC signals.
All inputs accept DC-coupled ground referenced 1Vpp input
signals. The ï¬lter outputs include +6dB of gain resulting in a
2Vpp signal into an AC-coupled dual video load (75â¦).
