ML6415
Overview
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, providing an area for the addition of the FM audio carrier(s) and mimic the group delay distortion introduced at the transmitter.
- 7.1MHz Y and C filters, with CV out
- 14dB notch at 4.5MHz for sound trap
- 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 3.0MHz and 3.58MHz is typically -170ns.
- No external frequency select components or clocks
- 9ns group delay flatness on Y, C, and CV output
- 5% overshoot on Y, C, and CV output edges
- 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
