FMS6400 Datasheet (Fairchild Semiconductor) - Dual Channel Video Drivers

FMS6400, Dual Channel Video Drivers

The FMS6400 is a dual Y/C 5th order Butterworth lowpass video filter optimized for minimum overshoot and flat group delay.

The device also contains a summing circuit to generate filtered composite video.

In a typical application, the Y and C input signals from DACs are AC coupled into the filters.
