1.2.8 PF_CCC_0

The PolarFire Clock Conditioning Circuitry (CCC) block takes an input clock of 156.25 MHz from the FAB_REF_CLK signal (output of PF_XCVR_REF_CLK) and generates a 156.25 MHz clock at OUT0 and 50 MHz clock at OUT1. The OUT1 port of the CCC is used for the configuration; OUT0 is used for the user logic in the design.
