I/O OD CMOS

3.3V/3.3V

I²C based control signal (clock) for SDVO device.
Note: If the control bus from the SDVO device has a different signaling voltage, then a level shifting device will be required on the carrier board to properly translate
the voltage level for this signal.

SDVO_CTRL_DAT

I/O OD CMOS

3.3V/3.3V

I²C based control signal (data) for SDVO device.
Note: If the control bus from the SDVO device has a different signaling voltage, then a level shifting device will be required on the carrier board to properly translate
the voltage level for this signal.
