To maintain the LT6555’s channel isolation, it is beneficial
to shield parallel input and parallel 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. See Figures 6 and 7 for photos of an optimized
layout.
Input Expansion
In applications with more than two inputs per channel,
multiple LT6555s can be connected by several different
methods. The simplest method is to connect the outputs
after the 75
series termination, as shown in Figure 2. The
compromise of this approach is that the internal gain
setting resistors cause a 435
shunt across the 75
cable
termination, resulting in increased gain error.

Figure 3 illustrates the loading effect of expanding the
number of inputs. The resultant gain error can be calcu-
lated by the following formula using n as the number of
LT6555s:

For example, two LT6555s would result in a gain error of
–0.74dB per channel. Three LT6555s (i.e., six red inputs,
six green inputs and six blue inputs), would have a gain
error of –1.4dB.
