Altinex DA1322AT Application Diagram, Input/Outputs, Channel Dip Swicthes, Sync Control Switches

DISTRBUTION AMPLIFIERS

4.1 INPUT/OUTPUTS

The outputs of the DA1322AT allow signals to be driven through 100 feet or more of cable depending on cable quality and the source signal resolution. The DA1322AT uses 5-BNC connectors for each input and output representing red, green, blue, and separate horizontal and vertical sync. When passing an RGBS format signal, simply use the horizontal channel to pass composite sync.

4.2 CHANNEL DIP SWICTHES

Each channel (RED, GREEN, and BLUE) of the DA1322AT has four dip switches: AC/DC, TERM, GAIN, and EQLZ.

The AC/DC switch is used to select AC or DC coupling of video signal through a distribution amplifier.

The TERM switch is used to terminate or unterminate RED, GREEN, & BLUE inputs with 75 Ohms.

The GAIN switch is used to set gain to 1 or 1.3.

The EQLZ switch is used to compensate for longer cable runs.

4.3 SYNC CONTROL SWITCHES

The DA1322AT has separate Sync control switches: TERM H, C SYNC, TERM V, and SYNC G.

The TERM H switch is used to terminate or unterminate horizontal sync input with 75 Ohms.

The TERM V switch is used to terminate or unterminate vertical sync input with 75 Ohms.

The C Sync switch is used with composite sync. The Sync G switch is used with sync on green.

4.4 BANDWIDTH

Offering a minimum video bandwidth of 350 MHz and typical bandwidth close of 500 MHz, the DA1322AT allows even very high resolution video signals to pass without degrading the image quality.

4.5 POWER

Designed with a universal power input connector, the DA1322AT offers a built-in linear power supply with continuous operation at 95V to 240V.
