SN74CBTLV3126: Does it support SMI (MDC/MDIO)

Part Number: SN74CBTLV3126

Hi team, 

    Does SN74CBTLV3126PWR support SMI interface? 

  

  • Alan,

    To determine if a switch can support a specific signal standard you are correct to look at the datarate and voltage level of the standard. 

    Do you know what data rate and voltage Serial Management Interface (SMI) you are trying to support?  What I have seen is that it can be up to 2.5MHz  

    The SN74CBTLVXXXX family of devices will support 200MHz bandwidth or up to 300Mbps data rate. 

    The propogation delay spec you mention above should not be an issue since almost all passive FET switches propogation delay is <1ns. 

    Let me know if this helped.

    Thank you,

    Adam
