S-Video Filter and 75W Line Drivers with Summed posite Output Features s s s 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. Both channels have DC restore circuitry to clamp the DC input levels during video sync. The Y channel uses a sync tip clamp. The CV and the C channels share a feedback clamp. All outputs must be AC coupled into their loads for the -1 and -3 versions. The -2 and -4 versions are DC coupled. All inputs (-1, -2, -3 and...
