Can the TS3A5018 switch the MDIO/MDC of DP83822?

Hello,

Can I use TS3A5018 for switching the MDIO/MDC signal of two DP83822?

Best Regards,

    Ryuji,

    To determine if a signal switch can successfully pass a signal through the switch you need to evaluate the bandwidth and the voltage swing.  The DP83822 datasheet states the MDC signal is 25MHz and up to 3.3 V.  You will need to find a switch with bandwidth > 25MHz and at least 3.3 V.  The  MDIO signal is pulled up to a voltage not greater than 3.3 V. 

    You can see that the TS3A5018 meets those requirements.

    We also have 182 other switches I found by filtering the TI.com switch selector tool with different packages, configurations, etc. if you need more options. 

    Thank you, 

    Adam
