FMS6366 Selectable YPbPr HD/SD 4:2:2 Video Filter Driver with Y, C and Composite Outputs
Features
Pin-compatible version of the FMS6419 for 4:2:2 video Requires external delay compensation 6th order standard/high definition video filters YPbPr 4:2:2 filters (8/30MHz : 4/15MHz : 4/15MHz) YC standard definition filters (8MHz) Composite summer output DC-coupled inputs, AC-coupled outputs

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

Outputs provide 6dB gain to 150 AC-coupled loads Dual multiplexed inputs 0.3% differential gain with 0.1 differential phase 5V only Lead free (Pb-free) packaging

Applications
Cable set-top boxes Satellite set-top boxes DVD players HDTV

Personal Video Recorders (PVR) Video On Demand (VOD)
