Set or query the external sample frequency. The internal sample clock f
Sa,i
is derived
from the sample clock provided at SCLK IN. For f
Sa,i
= 500 MSa/s…1 GSa/s the
sample clock input must be twice of f
Sa,i
. For f
Sa,i
= 250 MSa/s…500 MSa/s the sample
clock input must be four times f
Sa,i
.
For f
Sa,i
= 125 MSa/s…250 MSa/s the sample clock input must be eight times f
Sa,i
