GENERAL DESCRIPTION

The ML6428 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.

■ 1dB flatness up to 4.8MHz

■ No external frequency select components or clocks

■ 12ns group delay flatness up to 10MHz

■ 5 overshoot on any input edge

■ AC coupled input and output (ML6428CS-1 and -3)

■ AC coupled input and DC coupled output (ML6428CS-2 and -4)

■ 0.4 differential gain on all channels, 0.4º differential phase on all channels

■ 0.7 total harmonic distortion on all channels

■ 5V ±10 operation

■ DC restore with low tilt
