FUNCTIONAL DESCRIPTION
The ML6426 is a triple monolithic continuous time video
filter designed for reconstructing video signals from an
YUV/RGB video D/A source. The ML6426 is intended for
use in AC coupled input and output applications.
The filters approximate a 4th-order Butterworth
characteristic with an optimization toward low overshoot
and flat group delay. All outputs are capable of driving
2V
P-P
into AC coupled 150
W
video loads, with up to 35pF
of load capacitance. All outputs are capable of driving a
75
W
load at 1V
P-P
.
All channels are clamped during sync to establish the
appropriate output voltage swing range (DC restore). Thus
the input coupling capacitors do not behave according to
the conventional RC time constant. In most applications,
the ML6426's input coupling capacitors are only 0.1μF.
Figure 1. Typical Application Schematic
An external CMOS compatible H
SYNC
pulse is required
which is Active High on the SYNC IN Pin. See Figure 2.
During sync, the feedback clamp sources/sinks current to
restore the DC level. The net result is that the average
input current is zero. Any change in the input coupling
capacitors' value will linearly affect the clamp response
times.
Each channel is essentially tilt-free. Each input is
clamped by a feedback amp which responds to the output
during sync.
The ML6426 is robust and stable under all stated load and
input conditions. Bypassing both V
CC
pins directly to
ground ensures this performance.
