Starting the SuperClock-2 Module
The SuperClock-2 module features two clock-source components:
• Always-on Si570 crystal oscillator
• Si5368 jitter-attenuating clock multiplier
Outputs from either source can be used to drive the transceiver reference clocks.
To start the SuperClock-2 module:
1. The SuperClock-2 module is configured using the Xilinx XC7Z010CLG225
Zynq-7000APSoC System Controller command line which can be accessed through a
serial communication terminal connection using the enhanced communication port of
the Silicon Labs USB to Dual UART Bridge (
). Additional information about the
Silicon Labs USB-to-UART is available in
Silicon Labs CP210x USB-to-UART Installation
Guide
(UG1033)
Review the
VCU1287 Evaluation Board User Guide
(UG1120)
for additional
information about the System Controller.
2. Set the System Controller configuration DIP switches (SW13) to the OFF position
(
). This disables configuration of the FPGA at power reset.
