ML6428, S-Video Filter and 75 Line Drivers with Summed Composite Output

The ML6428 is a dual Y/C 4th-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.

The Y and C input signals from DACs are AC coupled into the ML6428.

Both channels have DC restore ci
