2- The Fairchild active filter and terminations must be place close to video connectors.
3- Analog video outputs are sensitive to noise coming from the power. Beads and inductors must be consider to clean the noise.
Try to keep a good noise immunity of your power traces and plane areas into the video output PCB area.
4- 37.4 Ohms resistors terminate the lines between BCM7440 and the active filters. They also polarize the 7440 VDAC outputs.
They 3.3V used for these pull-up must be very clean.
5- VDAC outputs traces must be routed according to the isolated traces rule. Trace_to_trace clearance >= 10 mils.
6- Place VDAC0/1_RBIAS resistors very very close to their BCM7440 pins (trace lenght <= 100mils).
VIDEO ANALOG --> Design notes and Layout Guidelines:
1- The Fairchild active filter are EDS protected.
1- Match the lenght of AUD_FS_CLK_0_A and AUD_FS_CLK_0_B.
