ML6415

S-Video Filter with Summed Composite Output,

Sound Trap, and Group Delay Compensation

Features

General Description

• 7.1MHz Y and C ﬁlters, with CV out

• 14dB notch at 4.5MHz for sound trap

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 gener-

ate ﬁltered composite video, an audio trap and group delay

compensation circuit to notch-out audio, providing 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.

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

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

• RF Modulator output differential group delay between

400kHz and 3.58MHz is typically -170ns.

• No external frequency select components or clocks

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

• AC coupled inputs and outputs

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

differential phase on Y, C and CV channels

• 0.8% total harmonic distortion on all channels

• DC restore with low tilt

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.

Applications

• Cable Set-top Boxes

• Satellite Set-top Boxes

• DVD Players

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

outputs can drive 2V into a 150Ω load (1V 75Ω coax

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

approximately 2 (6dB) with 1V input levels.
