Having selected the VIO Console, click the Si5368 Start button
transition arrow flashes ON/OFF to the right of Si5368 Done when the command is
complete.
Note:
The ROM address value for the Si5368 is preset to 52 to produce an output frequency of
156.25 MHz. Typing in a different address changes the frequency of the GTP transceiver
reference clocks. A complete list of frequency options and their associated ROM addresses is
provided in Table 5, page 27.
