TS3L500: Do you think TS3L500 is the right device for RGMII interfaces

e2e,

Do you think TS3L500 is the right device for RGMII interfaces?  Do you have an automotive version of this device?

Thank you,

Adam

    Hi Adam,

    I am assuming you are considering 1GHz RGMII interface. I am also assuming your RGMII interface consists of
    TXC, TX_CTL, TXD[3:0] ,
    RXC, RX_CTL, RXD[3:0].
    Clocks are 125MHz, while data bits are triggered on both rising and falling edge.

    If you want to switch 12 signals between two PHY or two MAC, the device you are looking for is 12 channel 2:1 with at least 125MHz bandwidth support. TS3L500 will not be a good fit since it is only 8 channel 2:1. TS3DDR4000 or TS3DV642 would be the 12-channel option.
     
    However, if you do not need to multiplex TXC, TX_CTL, RXC and RX_CTL and 8 channel are good enough, both TS3L500 and TS3L501 should meet your requirements. Currently, we do not have automotive TS3L500 or TS3L501.

    We have automotive USB switch of TS3USB221A-Q1, but you need 4 of them to serve 8 channel RGMII. Please also note the USB switch bandwidth is not specified at full VCC range.
