Hi Team,
My board is in the Testing stage of the project.
I am using SD 3.0-compliant voltage translator IP4856CX25/C.
I have SD connector interface supporting SD3.0 , when i connect SD card of UHS1 of class 10, 8GB,
the card easily gets detected as sd2.0, But the problem will arise when I connect SD card UHS3 class 4, 128GB; it will not get detected/not even SD2.0 until and unless I can solve this problem by
giving weak pull down or direct ground to clock pin of the connector/SD card; but the same work around(grounding by weak pull down) not required for UHS1 class 10, 8GB SD card.
Can you suggest me the solution for the problem, what else i can do in my schematics?.
Also can i know the internal architecture IC IP4856CX25/C with respect to ClOCK signal also i am seeing some feedback clock in this IC.
Waiting for your reply soon.
Thanks and Regards,
Ananthesh
