General Description

The FMS6406 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, an audio trap and group delay compensation circuit.

The audio trap removes video information in the spectral location of the subsequent RF audio carrier.
