FMS6366

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 1Vpp input signals. The filter outputs of FMS6366 include +6dB of gain resulting in a 2Vpp signal into an AC-coupled dual video load (75).
