Description

The FMS6400 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. 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 feed-

back clamps. The clamp pulse is derived from the Y channel.

All outputs are capable of driving 2V

either a single or dual video load. A single video load consists of

a series 75Ω impedance matching resistor connected to a ter-

minated 75Ω line. This presents a total of 150Ω of loading to the

part. A dual load would be two of these in parallel which would

present a total of 75Ω to the part. The gain of the Y, C and CV

signals can be selected for 0dB or 6dB with 1V

video channels are clamped during sync to establish the appro-

priate output voltage reference levels.

The FMS6400 typical cutoff frequency is 7.1MHz. Option for a

lower cutoff frequency of 5MHz is available. Please refer to the

FMS6400-1 datasheet for further information.
