General DescriptionThe 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 gener-
ate filtered 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.
