ABOUT YOUR DISTRIBUTION AMPLIFIER 2
The
DA1804NT
is a 1-in 4-out distribution amplifier
designed to allow the connection of a single video
source to as many as four display or recording
devices.
The
DA1804NT
can pass NTSC, PAL, and SECAM
- type composite video signals. It can also pass
high-resolution monochrome computer video, such
as grayscale signals used in medical imaging. The
DA1804NT
can handle video signals with levels up
to 1.5V p-p.
With state-of-the-art ICs, the
DA1804NT
offers a
bandwidth of 350 MHz with a very flat frequency
response up to 200MHz. It also offers a differential
gain of 0.15% and a differential phase of 0.15
degrees.
The
DA1804NT
Distribution Amplifier has a pre-set
gain of 1.05. Each output id is completely
independent and can withstand shorts to ground
indefinitely. Extremely rugged and compact, the
DA1804NT
fits easily into tight spots. Using a high
quality 75 Ohms coaxial cable, it can drive an
NTSC signal 400 feet or more.
