Using ADV7391 for Genlock - Black Burst


I'm using an ADV7391 on my development design to produce a Genlock (Black Burst) signal from DAC 1 that the system requires. The datasheet for the part recommends an output buffer and an optional reconstruction (anti-imaging) low pass filter in various forms for SD, ED, and HD. Do I require any special requirements if I want to use the DAC1 output for Genlock?
