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 amplifi er is con-
fi gured in a gain of 2, with a 75Ω back-termination resulting
in a fi nal 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 amplifi er is biased to mid-supply
with a high impedance resistor divider.
As seen below, the DC1063A is a 2-sided board.
