Description
The FMS6406 is a dual Y/C 5th 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, an audio trap and group delay compensation
circuit. The audio trap removes video information in the spectral
location of the subsequent RF audio carrier. The group delay
circuit predistorts the signal to compensate for the inherent
receiver IF filter’s group delay distortion.
In a typical application, the Y and C input signals from DACs are
AC coupled into the filters. Both channels have DC restore circuitry
clamp the DC input levels during video sync. The Y and C channels
use separate feedback clamps. The clamp pulse is derived from
the Y channel.
to
All outputs are capable of driving 2V
either a single or dual video load. A single video load consists of
a series 75
impedance matching resistor connected to a ter-
minated 75
line, this presents a total of 150
part. A dual load would be two of these in parallel which would
present a total of 75
to the part. The gain of the Y, C and CV
signals is 6dB with 1V

input levels. All video channels are
clamped during sync to establish the appropriate output voltage
