The DigiFlex 1153 Video DA is a state of the art
analog video distribution DA with equalization and
clamp. The 1153 provides high-p erformance video
distribution in the LINK DigiFlex 1000 Frame. The
advantage is obvious: both analog and digital
distribution amplifiers can operate side-by-side in
a single frame!
Utilizing the latest CMF Op-Amp technology, the
1153 combines wide bandwidth, low noise, and
low power consumption. The video path is truly
transparent, with differential phase and gain errors
of <0.1°
noise ratio exceeds 65dB. Eight outputs are
provided on it’s companion rear cell, 1011.
and <0.1%, respectively. Video signal-to-
Mounting Frame Options
1000 - Single Power Supply, Holds 11 Modules
1000/2 - Dual Power Supply, Holds 10 Modules
7200 - Mounting Frame, Holds 1 Module
DC-coupled differential input is a standard feature,
providing high common-mode rejection. Eight
outputs are available on the rear panel. Cable
equalization is adjustable from the front card edge
and can compensate for loss in coax cable up to
1000 feet of Belden 8281. The feedback clamp
on/off is front panel controlled. Clamp is
referenced to back porch.
The attention to detail in the design of the 1153
extends to the power supply, which features a
simple switching regulator. While slightly more
complex than a linear supply, this offers the
highest possible efficiency. Backed by a ten-year
warranty including parts and labor.
