(seen from the top), the switch is closed.  The schematic for the board indicates the functions of each 
switch.  The switch functionality is summarized in Table 1 below. 

Two headers are also provided for operating the control lines of the LMH0356 SDI reclocker.  The first is 
located immediately below the DIP switches.  This header is meant to be used with two-pin jumpers and 
provides parallel functionality to the DIP switches.  When a jumper is installed on the header it overrides 
the function of the equivalent DIP switch. 

The second header is located to the right of the DIP switches.  This header is meant to provide access for 
remote control of the LMH0356 SDI reclocker.  When this header is used the DIP switches should all be 
set in the open position and no jumpers should be installed on the control header.  The connections for 
this header are described in the schematic for the SD356EVK PC board.  It is recommended that this 
header only be used for advanced control applications and only by users familiar with the operation of the 
LMH0356 SDI reclocker. 

LED indicators are provided near the top of the board to indicate the state of the control inputs and the 
indicator outputs of the LMH0356 SDI reclocker.  The LED states and their meanings are summarized in 
Table 1.
