General Description
The ML6429 is a quad 4th-order Butterworth lowpass recon-
struction filter plus quad video amplifier optimized for mini-
mum overshoot and flat group delay. Each filter channel has
a two-input multiplexer that switches between two groups of
quad video signals. Applications driving SCART and EVC
cables are supported for composite, component, and RGB
video.

coupled, and drive 2V
be used with DC coupled outputs for certain applications.
A fifth unfiltered channel is provided to support an additional
analog composite video input. A swapping multiplexer
between the two composite channels allows the distribution
amplifiers to output from either input.
Several ML6429s can be arranged in a master-slave configu-
ration where an external sync can be used for CV and RGB
outputs.
