Hi sir, 

Qualcomm IQX eUSB is 1.2V.

So should we use TUSB2E112 or TUSB2E111??

TUSB2E112 I/O power should connect to 1.2V or 1.8V?

Another question is 1.2V eUSB level shift should choice TUSB2E112 or TUSB2E111?

    Hi Sean,

    The TUSB2E11 requires a 3.3V and 1.8V power supply.

    For GPIO/I2C voltage, it is up to the customer which they want to use.

    If the customer wants to use 1.8V GPIO/I2C, then the customer should use TUSB2E111.

    If the customer wants to use 1.2V GPIO/I2C, then the customer should use TUSB2E112.

    For eUSB2 signaling, both variants will 1.2V eUSB2 signaling.

    Thanks,

    Ryan
