Notes:
1. The V_OH specification does not apply to the open-drain SDA/SDIO output when the serial interface is in I²C mode or is
unused with I2C_SEL pulled high. V_OL remains valid in all cases.
2. V_DDIO is determined by the IO_VDD_SEL bit. It is selectable as V_DDA or V_DD. Users normally select this option in the
ClockBuilder Pro GUI. Alternatively, refer to the Si5347-46 Family Reference Manual for more details on register
settings.
