TYPICAL APPLICATIO
U
RGB Buffer Demo Board
The DC714 Demo Board illustrates optimal routing,
bypassing 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 input shunt and output series
terminations are connected as close to the part as pos-
sible. For ideal operation, a 75
load termination should
be connected at the output. The LT6553’s gain of 2 will
compensate for the resulting divider between the series
and load termination resistors.

APPLICATIO S I FOR ATIO
WU
UU
If the AGND pins are not connected directly to a low
impedance ground plane, they must be carefully bypassed
to maintain minimal impedance over frequency. Pin 6 is a
shared connection of the gain resistors of both channel G
and channel B, and any resistance external to this node can
significantly decrease the isolation between those chan-
nels. Although crosstalk will be very dependent on the
board layout, a recommended starting point for bypass
capacitors would be 470pF as close as possible to each
AGND pin with one 4700pF capacitor in parallel.
To maintain the LT6553’s channel isolation, it is beneficial
to shield parallel input and output traces using a ground
plane or power supply traces. Vias between topside and
backside metal may be required to maintain a low
inductance ground near the part where numerous traces
converge.
ESD Protection
The LT6553 has reverse-biased ESD protection diodes on
all pins. If any pins are forced a diode drop above the
positive supply or a diode drop below the negative supply,
large currents may flow through these diodes. If the
current is kept below 10mA, no damage to the devices will
occur.
