I plan to use two NVT4858s between HOST and SD CARD. A
Host (Our SOC) >>>> NVT4858(1.8V to 3.3V) >>> SD CARD
DATA[3:0], CMD, DQS, LPBK signals synchronized to CLK are required.
So I plan to use two NVT4858s.
NVT4858 #1 : CLK, CMD, DATA[3:0]
NVT4858 #2: DQS, LPBK
Is there a critical issue with the timing difference between the two separate level shifters?
All signals are synchronized to CLOCK.

Should be no more issue for this application.
Thx. If you have time, please check my schematic.
