TS5A23159: As a MDIO MUX

Part Number: TS5A23159
Other Parts Discussed in Thread: SN74LVC1G3157, TS5A23157

HI,

Currently we need an application including MDIO signal conditioning + MUX application as below.   The MDIO signal speed is 2.5MHz~5MHz.   It seems TS5A23159 can satisfy the need for the MUX function as below.  May I have your comments/confirmation about it?  Or do you have better proposal for this 1.8V(right)/3.3V(left) MUX?

Thanks!

Antony

  • Antony,

    All of TI's passive FET switches can handle >15MHz signals so you could choose any 2:1 switch in the portfolio.

    There is a low cost 1-channel 2:1 mux SN74LVC1G3157 that may also work here for the mux on the left.

    For the 2 muxes on the right the TS5A23157 is a little bit lower cost than the TS5A23159.

    Thank you,
    Adam
