TPD4EUSB30: TVS diode for MIPI D-PHY 2.1Gbit/s

Part Number: TPD4EUSB30
Other Parts Discussed in Thread: TPD4E1U06

Hello,

Can you please let me know if TI does any TVS diodes targeted especially at MIPI D-PHY 2.1Gbit/s? I use TPD4EUSB30 for USB3.0 protection already and If I do not find anything specially designed for MIPI might use the same on MIPI ( after all it is only 2.1Gbit).I have found one made by Nexperia PCMFxUSB30 which is also primarily USB device but MIPI is mentioned in their data sheet, maybe you do have an equivalent.

Thanks

Sebastian

    Hi Sebastian, 

    Yes, we do have devices that we typically recommended for MIPI interfaces. The devices are: TPD4E1U06, TPD2S017, TPDxF003 (EMI filter w/ ESD), TPD6F002 (EMI filter w/ ESD). 

    Please let me know what you think of these recommendations or if you have any questions. 

    Best Regards,

    Thanks for that ,

    It is very usefull, I had looked at these and : TPD4E1U06 looks like best from ESD perpective, it complies to all standards I am interested in but in the Data sheet there is no mention of  speed of interfce (apart from 1pF capacitance and IL loss graph which is not looking bad actually). 

    On the contrary (what puts me off ) theere is example of USB2.0 ( I'd expect USB3.0 5Gbit) instead. MIPI is mentioned but with no specification of actual speed. Suitability for Display Port would be a good indicator but there is no version of DP given ( 1.0 is 1.62Gbit/s while 2.0 is 20 Gbit/s ).

    Is there any chance to get some more info of potential application for higher speed ( 2.1 Gbit/s ) .interfaces? 

    Thanks and best regards

    Hi Sebastian, 

    Yes, I did just notice there is no mention of speed in the datasheet. Unfortunately, this is an older device of ours and don't have access to the data. If you are interested in this specific device then I can reach out to other team members to try and find the information you need. 

    I did want to also recommend TP4E05U06. This device doesn't specifically mention MIPI as an application but that is because we only list a few applications. This device is similar to TPD4E1U06, but it actually states that it is able to support speeds up to 6 Gbps. Also, I know you mentioned using TPD4EUSB30 in the past and is able to support speeds up to 7.4 Gbps. 

    Please let me know if you need any clarification or have more questions. 

    Best Regards, 

    McKenzie

    Hi,

    I was reading about TP4E05U06 today as I have found it being suggested on the forum, I am glad you mentioning it assures me I am going in the right direction. I think I got right pointers so will be able to choose the protection, thanks a lot for your help.
