Hi,

I am using NVT4858 as the level shifter for eMMC and OSPI. The circuit schematic is as follows: May I ask how to deal with the unused CLK, CMD and DATA pins? Is it OK just to unconnected? Please give your suggestions on the following circuit. Thank you.

To add: +V_ADJ is 1.2V. The NVT4858 converts eMMC and OSPI from 1.2V to 1.8V. Thanks.

Hello @tilnxpsyna ,

Thanks for your post.
Since this is a DSC channel, that product is beyond the scope of my support. I suggest you create a new post on High Performance Analog Front End Interfaces - NXP Community. The supporters will assist you further.

Hope it can help you.

BRs,

Celeste
