Notes:

1. The VOH specification does not apply to the open-drain SDA/SDIO output when the serial interface is in I

2C mode or is

unused with I2C_SEL pulled high. VOL remains valid in all cases.

2. VDDIO is determined by the IO_VDD_SEL bit. It is selectable as VDDA or VDD. 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.
