[11-111-102] - 1x2 Composite Video Distribution Amplifier

Description

The 11-111-102 is a one input to two output composite video distribution amplifier with a single ended input (75 Ohm termination).

This unit has unity gain between the input and all four outputs. 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.

Common Application

The common application of this unit is to generate two copies of a single composite video signal so two 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 level 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 very basic linear power supply with a 12 VAC input voltage requirement. A 12 VAC wall transformer (120 VAC input) is supplied with each unit. By using the wall transformer the power system provides ground isolation between the input power and the video circuits. The power supply uses a half wave rectifier design to develop the internal positive and negative voltage rails for the active operational amplifiers.

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.
