S-Video Filter And 75 ?٠Line Drivers With Summed Composite Output

The ML6428 is a dual Y/C 4th-order Butterworth lowpass Video lter optimized for minimum overshoot and at group delay. The device also contains a summing circuit to gener- ate ltered composite 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 version. The -2 version must be DC coupled. All inputs (-1 and -2 versions) are AC coupled. The Y or C outputs CAN drive 2VP-P into a 150 load, while the CV output CAN drive 2VP-P into 75. Thus the CV output is capable of driving two independent 150 loads to 2VP-P. On the CV output, one of the 75 loads CAN be shorted to ground with no loss of drive to the remaining load. The Y, C and CV channels have a gain of 2 (6dB) with 1VP-P input levels.
