This systematic gain error can be significantly reduced by  
loweringthevalueofthe75Ωseriesterminationresistors.  
The compromise of this approach is an increased depen-  
dence on the accuracy of the 75Ωshunt termination at the  
receiving end of the line. A table of values for 1% series  
termination resistors from n = 2 to n = 4 is shown below.

Another approach that does not compromise gain accu-  
racy is to connect the outputs directly together before the  
series termination. In this case, there will be slightly  
increased output glitching and supply current spiking  
during the EN pin switching, but the additional output  
loading will not increase the gain error, and the series  
termination resistors remain at their ideal value for AC  
response. See Figure 4 for a scope photo showing the  
result of the outputs connected both before and after the  
series terminations, and Figure 8 for a full schematic of a  
4:1 RGB multiplexer with the output pins directly con-  
nected together. It is imperative that the output traces be  
as short as possible before the series termination in order  
to reduce capacitance and minimize AC peaking.

ESD Protection  
The LT6555 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.

possible. The board is fabricated with four layers with  
internal ground and power planes. For ideal operation, a  
75Ω load termination should be connected at the output.  
The LT6555’s gain of 2 will compensate for the resulting  
divider between the series and load termination resistors.  
Figures 6 and 7 show the topside and bottom side board  
layout and placement.  
The DC858A Demo Board illustrates optimal routing,  
bypassing and termination using the LT6555 as an  
RGB video multiplexer. The schematic is shown in Fig-  
ure 5. All inputs and outputs are routed to have a charac-
