SDIO 3.0 Range Extender

Michael Yeo

Team,

I saw SN74AVCA406E supports SDIO 3.0 level shifting up to 100MHz clock rate. Please let me know whether this device can be used as range extender which will support longer than 100mm of PCB trace length.

From the spreadsheet in below, SN74AVCA406E requires "Power Mux" for SD 3.0 interface. Please share the detailed design guide for it.

Thank you in advance!

    Hello Michael,

    On page 15 of the datasheet we can see the Parameter Measurement Information specifies that all measurements were taken with a capacitive load of 15pf. As long as the trace does not introduce a capacitive load of greater than 15pf the SN74AVCA406E should be fine without the use of a power mux.
