TYPICAL APPLICATIONS

Application (Demo) Boards

The DC1063A demo board has been created for evaluating

the LT6559 and is available directly from Linear Technol-

ogy. It has been designed as an RGB video buffer/cable

driver, using standard VGA 15-pin D-Sub (HD-15) con-

nectors for input and output signals. All sync signals are

also passed directly from the input to the output, so the

LT6559’s performance can be determined by applying a

5V supply to the DC1063A demo board and then inserting

the board between a computer’s analog video output and

a monitor. Schematics for the DC1063A demo board can

be found on the back page of this datasheet.

As seen in the DC1063A schematic, each ampliﬁer is con-

ﬁgured in a gain of 2, with a 75Ω back-termination resulting

in a ﬁnal gain of 1. Each input is properly terminated for

75Ω input impedance with AC coupling capacitors at each

input and output. Additionally, for proper operation, the

positive input of each ampliﬁer is biased to mid-supply

with a high impedance resistor divider.

As seen below, the DC1063A is a 2-sided board.
