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 to 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.
All outputs are capable of driving 2V
into either a single or dual video load. A single video load
consists of a series 75W impedance matching resistor
connected to a terminated 75W line, this presents a total
of 150W of loading to the part. A dual load would be two of
these in parallel which would present a total of 75W 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 reference levels.
