FMS6404 - PRECISION COMPOSITE VI

The FMS6404 is a single composite video 5th-order Butterworth low-pass video filter optimized for minimum overshoot and flat group delay. The device contains an audio trap that removes video information in a spectral location of the subsequent RF audio carrier. The group delay compensation circuit pre-distorts the signal to compensate for the inherent receiver intermediate frequency (IF) filter’s group delay distortion.In a typical application, the composite video from the DAC is AC coupled into the filter. The CV input has DC-restore circuitry to clamp the DC input levels during video synchronization. The clamp pulse is derived from the CV channel.All outputs are capable of driving 2VPP, AC- or DC-coupled, into either a single or dual video load. A single video load consists of a series 75Ω impedance matching resistor connected to a terminated 75Ω line. This presents a total of 150Ω of loading to the part. A dual load would be two of these in parallel, which presents a total of 75Ω to the part. The gain of the CV signal is 6dB with 1VPP input levels. All video channels are clamped during synchronization to establish the appropriate output voltage reference levels.
