ML6428 Datasheet S-video Filter And 75 Line Drivers With Summed Composite Output

Manufacturer: Fairchild (now onsemi)

Overview: .fairchildsemi. ML6428 S-Video Filter and 75Ω Line Drivers with Summed posite.

General Description

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 posite video.

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