VCU1287 IBERT Getting Started Guide
All multi-gigabit transceiver (MGT) pins and reference clock pins are routed from the FPGA
to a connector pad that interfaces with Samtec Bulls Eye connectors.

connector pad.
B
shows the connector pinout.
The SuperClock-2 module provides LVDS clock outputs for the MGT transceiver reference
clocks in the IBERT demonstrations.
shows the locations of the differential clock
SMA connectors on the clock module which can be connected to the reference clock cables.
The four SMA pairs labeled CLKOUT provide LVDS clock outputs from the Si5368 clock
multiplier/jitter attenuator device on the clock module. The SMA pair labeled Si570_CLK
provides LVDS clock output from the Si570 programmable oscillator on the clock module.
Note:
The Si570 oscillator does not support LVDS output on the Rev B and earlier revisions of the
SuperClock-2 module.
