Other Parts Discussed in Thread: TDA4VM, TDA4VH
Hello TI team,
We are considering an UFS 3.1 from Micron to be connected with a TDA4VM-Q1 on our board.
JEDEC UFS specification says it ensures backwards compatibility with previous generations (TDA4 only supports UFS 2.1).
But our UFS reference is powered with VCC at 2.5V or 3.3V (user's choice) and VCCQ at 1.2V (VCCQ2 not connected).
On the EVM, the UFS implemented is a THGAF8G8T23BAIL with VCC at 3.3V and VCCQ2 at 1.8V (VCCQ not connected).
The UFS peripheral of the TDA4 is powered by VDDA_1P8_UFS, so we think UFS0_REF_CLK and UFS0_RSTN are 1.8V signals which are not compatible with our UFS which expects to receive 1.8V signals.
Do you know if there is a possibility to use UFS 3.1 devices with a TDA4VM? By for e.g. adapting CLK and RSTN levels with voltage divider like circuitry?
Are the 2x SERDES lanes also concerned by voltage levels issues?
Thank you.
Regards,
Thibaut
