ML6426
High Bandwidth Triple Video Filters with Buffered
Outputs for RGB or YUV
1
GENERAL DESCRIPTION
The ML6426 are a family of triple video filters with
buffered outputs. There are several versions of the
ML6426, each with different passband cut-off frequencies
of 6.7MHz, 12MHz, 24MHz, 30MHz, 36MHz, and
48MHz. Each channel contains a 4
th
-order Butterworth
lowpass reconstruction video filter. The filter is optimized
for minimum overshoot and flat group delay and
guaranteed differential gain and phase at the outputs of
the integrated cable drivers.
All input signals from DACs are AC coupled into the
ML6426. All channels have DC restore circuitry to clamp
the DC input levels during video H-sync, using an output
feedback clamp. An external H-sync signal is required for
this purpose.
All outputs must be AC coupled into their loads. Each
output can drive 2V
P-P
into a 150
W
load. All channels
have a gain of 2 (6dB) at 1V
P-P
input levels.
