Procedure
An always-on Si570 crystal oscillator and an Si5368 jitter-attenuating clock multiplier. The
IBERT demonstration uses the output from the Si5368 device to clock the GTP transceivers.

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.
