As shown in
Table 5-2
and
Table 5-3
, both two Si5340 control IPs have preset several
output frequency parameters, if users want to change frequency, users can fill in the
input port " iPLL_OUTX_FREQ_SEL" with a desired frequency value and recompile the
project. For example, in Si5340A control IP, change
.iPLL_OUT1_FREQ_SEL(`SI5340A_125M),
to
.iPLL_OUT1_FREQ_SEL(`SI5340A_156M25),
Recompile project, the Si5340A OUT2 channel (for QSFP-C ) output frequency will
change from 125Mhz to 156.25Mhz.
