LT6551

DESCRIPTION

Demonstration circuit 866 is a Quad Video Amplifier fea-

turing the LT6551. The Demo Circuit is designed to oper-

ate from a single po er supply from 4.5V to 12V. The

inputs and outputs are ac-coupled and include 75

Ω

ter-

minations for video cables. The LT6551 has a fixed volt-

age-gain of t o, thus ith a terminated output cable, the

net gain is nominally unity.

Design files for this circuit board are available. Call

the LTC factory.

OPERATING PRINCIPLES

DC866 provides four identical channels of ideband sig-

nal amplification suitable for driving HDTV or high-

resolution RGB video display cables. Each amplifier sec-

tion of the LT6551 provides a fixed gain of 2, and ith

series “back-termination” at the outputs (included on the

board), results in unity gain transmission of a video sig-

nal to a destination load, ith frequency response sho n

in Figure 2.

Each input is terminated to analog ground to properly

load the input signal cable. AC-coupling is provided for

both inputs and outputs, along ith biasing circuitry, to

provide single-supply operation. Figure 3 sho s the typi-

cal crosstalk bet een adjacent channels.

Figure 4 sho s the material list of the components used

by DC866, and Figure 5 sho s the electrical interconnec-

tion.

QUICK START PROCEDURE

Demonstration circuit 866 is easy to set up to evaluate

the performance of the LT6551. R efer to Figure 1 for

proper measurement equipment setup and follo the

procedure belo :

Prior to connecting the po er supply, preset the out-

put voltage to 5V, or to the desired level, if different.

W ith po er off, connect the po er supplies to V+ and

GN D using banana to clip-lead cables.

If using a Net ork Analyzer, perform the THR U trans-

mission cal ith all cabling, adapters, impedance con-

verters, etc. in place as the reference 0dB path.

Energize the po er supply.

Connect the N et ork Analyzer (if used) to the appro-

priate channels to measure frequency response and

crosstalk as desired.

For video-signal evaluation, connect a component-

video signal source to the inputs and a monitor and/or

video analyzer to the outputs.
