TYPICAL APPLICATIO
RGB Buffer Demo Board
The DC714 Demo Board illustrates optimal routing, by-
passing and termination using the LT6553 as an RGB
video buffer. The schematic is shown in Figure 1. All inputs
and outputs are routed to have a characteristic impedance
of 75
and 75
shunt and series terminations are con-
nected as close to the part as possible. For ideal operation,
a 75
shunt termination should be connected at the
output. The LT6553’s gain of 2 will compensate for the
resulting divider between the series and shunt termination
resistors.
A fourth signal trace is provided at the bottom of the
board with dimensions identical to the combined input
and output of the other channels. This trace can be used
for calibrating out the effects of electrical delay and
U
impedance mismatching and is not necessary in an end-
user application. Several jumpers and additional connec-
tors are also included to allow for testing of the enable
feature and single supply operation.
RGB Video Selector/Cable Driver
A video multiplexer can be implemented using the EN pins
of parallel LT6553s as shown in Figure 2. In this applica-
tion, all outputs are connected together and one LT6553 is
switched on while the other is switched off. A fast inverter
is used to ensure that only one set of R, G and B channels
is buffered at any time. As shown, the outputs are con-
nected before the 75
series termination resistors in
order to reduce any DC attenuation that may result from
the non-infinite output impedance of the disabled LT6553.
