ML6415 S-Video Filter with Summed Composite

Output, Sound Trap, and Group Delay Compensation

GENERAL DESCRIPTION

FEATURES

The ML6415 is a dual Y/C 4th-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 to notch-out audio, pro-

viding an area for the addition of the FM audio carrier(s)

and mimic the group delay distortion introduced at the

transmitter. The group delay predistortion compensates

for the nominal TV receiver IF ﬁlter distortion.

n 7.1MHz Y and C ﬁlters, with CV out

n 14dB notch at 4.5MHz for sound trap

n 42dB stopband attenuation at 27MHz on Y, C, and CV

n Better than 1dB ﬂatness to 4.5 MHz on Y, C, and CV

n RF Modulator output differential group delay between

3.0MHz and 3.58MHz is typically -170ns.

In a typical application, the Y and C input signals from

DACs are AC coupled into the ﬁlter. Both channels have

DC restore circuitry to clamp the DC input levels during

video sync. The Y and C channels use a separate feedback

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

n No external frequency select components or clocks

n 9ns group delay ﬂatness on Y, C, and CV output

n 5% overshoot on Y, C, and CV output edges

n AC coupled inputs and outputs

The outputs are AC coupled. The Y, C, CV, and modulator

outputs can drive 2Vp-p into a 150Ω load (1Vp-p 75Ω

coax load). The Y, C, CV, and notch channels have a gain

of approximately 2 (6dB) with 1Vp-p input levels.

n 0.4% differential gain on Y, C and CV channels, 0.4º

differential phase on Y, C and CV channels

n 0.8% total harmonic distortion on all channels

n DC restore with low tilt

APPLICATIONS

n Cable Set-top Boxes

n Satellite Set-top Boxes

n DVD Players
