2.4. Reference and System PLL Clock for Your IP Design

Each GTS system must instantiate one GTS reference clock.
The GTS Reference Clocks Intel FPGA IP performs the following main function:
  1. Configure reference clock for FGT PMA:
    • Enable FGT reference clocks and specify the reference clock frequency
    • Specify FGT CDR output
When you design multiple interfaces or protocol-based IPs within a single GTS, you must use only one instance of the GTS Reference Clock FPGA IP to configure:
  • All required reference clocks for FGT PMA to implement multiple interfaces within a single GTS.
