Output Y0 from the clock buffer LMK1C1103PWR is used as a reference clock for the SoC on SKEVM. An optional 25-MHz crystal (XRCGB25M000F3M00R0) is also provided for driving the SoC. Selection of clock for the SoC is done using resistors. By default, an output from the SoC_CLKIN clock buffer is provided to the SoC. For clock source selection, see Table 4-1.
Clock Source to SoC | Part Number | Mount | Unmount |
