FMS6406

Precision S-Video Filter with Summed Composite Output,

Sound Trap, and Group Delay Compensation

Features

Description

■ 7.6MHz 5th order Y,C ﬁlters with composite summer

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.

■ 14dB notch at 4.425MHz to 4.6MHz for sound trap

capable of handling stereo

■ 50dB stopband attenuation at 27MHz on Y, C and CV outputs

■ Better than 0.5dB ﬂatness to 4.2MHz on Y, C and CV outputs

■ Equalizer and notch ﬁlter for driving RF modulator with group

delay of -180ns

■ No external frequency selection components or clocks

■ < 5ns group delay on Y, C and CV outputs

■ AC coupled inputs

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.

■ AC or DC coupled outputs

■ Capable of PAL frequency for Y,C,CV

■ Continuous Time Low Pass Filters

All outputs are capable of driving 2V , 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 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

■ < 1.4% differential gain with 0.7° differential phase on Y, C

and CV channels

■ Integrated DC restore circuitry with low tilt

Applications

signals is 6dB with 1V input levels. All video channels are

clamped during sync to establish the appropriate output voltage

reference levels.

■ Cable set-top boxes

■ Satellite set-top boxes

■ DVD players
