ML6427
75W Quad Video Cable Drivers and Filters
with Switchable Inputs
GENERAL DESCRIPTION
The ML6427 is a quad 4th-order Butterworth lowpass
reconstruction filter plus quad video amplifier optimized
for minimum 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.
1VP-P input signals from DACs are AC coupled into the
ML6427 where they are DC restored. Outputs are AC
coupled and drive 2VP-P into a 150W load. The ML6427
can provide 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 ML6427s can be arranged in a master-slave
configuration where an external sync can be used for CV
and RGB outputs.
