hello,
when configiure the cpri 5x link rate, the sys_clock should be 245.76M or 307.2M. it means if the input reference clock is 122.88M, then the SD_PLL_B8_CFG.MPY_B8 and SD_PLL_B4_CFG.MPY_B4 should be set 20x or 25x?

Hi,
CPRI 5x is very special and you have to use 307.2 MHz ref clock like OBSAI and you can set 25x for your SERDES PLL.
