Introduction UDA-8005A User Manual (Iss. 01)
Overview
The UDA-8005A is an analog general-purpose distribution amplifier. It is very useful in digital
systems when there is a requirement for the distribution of a few analog signals, such as a color black
reference. Use of this amplifier will avoid the need to purchase a separate analog Video Products rack
frame and power supply.
The UDA-8005A is a general-purpose amplifier for use in the distribution of video. It is intended for
use in situations where cable equalization and differential input are not important, and clamping is not
required. Gain is adjustable over a wide range of
±
3dB.
This amplifier is DC-coupled and will faithfully provide all aspects of a video input signal to eight
identical output copies with very low distortion. The use of new generation integrated circuits and
innovative engineering has resulted in excellent performance combined with economy.
The UDA-8005A card is designed for use in the RossGear 8000 series video frames. The power to
each card is individually fused to prevent failure of any one card from affecting the rest of the cards in
the frame. RossGear analog (and digital) cards are also designed to fit into distribution frames of some
other manufacturers for installation flexibility.
