Part Number: TCA39306

Tool/software:

How well is TCA39306 is I3C compatible? MIPI I3C version 1.1 Supported?

Will it work for the implementation? (Attached block diagram)

We need TCA39306 as buffer, will it work?

Any recommendations?

Hello Aswin,

Our apps team is current out today celebrating Labor Day (US Holiday). Allows us two days to respond back. Thank you for your understanding.

Hi Aswin,

TCA39306 can level translate I3C signals at 12.5 MHz. It is a purely passive device with no digital, it will not recognize I3C traffic.

This device will level translate according to the block diagram, but it does not buffer. 1.8V to 3.3V is a valid use case for this device, external PU resistors are required on both sides of the level translator for it to work.

Regards,

Tyler

Hi Aswin,

An additional question from the team:

Are you looking for a voltage translator, a buffer/re-driver, and protocol conversion from SMBus to I3C?

Regards,

Tyler
