The MIPI DSI TX Subsystem sub-core MIPI D-PHY uses an MMCM to generate the general interconnect clocks, and the PLL is used to generate the serial clock and parallel clocks for the PHY. The input to the MMCM is constrained as shown in Clock Frequencies section of MIPI D-PHY LogiCORE IP Product Guide (PG202) [Ref 4] . No additional constraints are required for the clock management.
