selecting input SDI0.
Other selection settings
can be used with other
SDI inputs.
This is the setting for
automatic rate detect.
The rate selection
switches can also be set
to match the data rate
input. For a 1.4835 Gb/s
signal as described here,
Rate0 can be off and

LMH0356 is powered up.
The indicator will be red if
a 270 Mb/s signal is
used.
The indicator will be off if
a non-supported data
rate is used.
