Overview

Common Application

The common application of this unit is to generate two copies of a single composite video signal so the downstream devices can be driven without degradation of the video quality. Because this is an active device (requires power) signal quality as well as signal levels are maintained while generating the multiple copies of the original signal. The high bandwidth of this unit insures the input video signal is not modified due to bandwidth roll off (DC – 200 MHz bandwidth at -3db level).

Power Supply

This unit has a non-isolated internal switcher power supply (FlexPWR). The unit will operate correctly on 10-28 VAC or 10-32 VDC. The power input is protected so power can be applied in either polarity. The supply provides the internal electronics with power with the ground of the video circuits being the same as the input power ground. The power connector is a 2-pin 2.5mm terminal block with detent retention that can support high vibration environments.

Package

The package for this unit consists of a solid epoxy block. The internal electronics are assembled and tested before the encapsulation process. During the encapsulation the printed circuit board(s) are placed in a five sided box made of RTV mold parts. The cavity is filled with epoxy and the lid (top) of the mold is inserted. The curing process takes 24 hours. This type of package seals the electronics so water and contamination cannot affect the internal electronics. This type of package also provides superior resistance to shock and vibration compared to a metal or plastic box enclosure.

Description

A one input to four output composite video distribution amplifier with a single differential input (75 Ohm termination). This unit has a gain pot for each output. Unused outputs do not need to be terminated with 75 Ohms. All of the video connections are BNC connectors. This unit is intended to be used with NTSC or PAL video signals.
