ADG715 in UART Switching

I have selected ADG715 for switching the UART(Tx,Rx) signals. We selected this IC to switch TX,RX signals between the microcontroller and PC. I want to know would that switch provide the effective switching speed for serial communication?

    Hi Mohsin,

    Apologies of the delay in answering your question.

    When you ask what switch would provide the effective switching speed for serial communication ?

    Are you referring to:

    • How fast the switch will turn ON or OFF, when switching form RX to TX channels ?

    Or

    • Would this be suitable to switch to pass a high frequency signal from a serial connection ?

    Please let me know your thoughts.,

    Kind regards,

    Kevin

  • Thanks Kevin for the reply. Yes my question related to:

    • Would this switch be suitable to pass a high frequency signal from a serial connections ?

    Kind regards,

    Hi Mohsin,

    Good morning,

    On my side, I'm finding it hard to get a defined frequency range on Rx and Tx, it also depends on the USB generation. 

    The serial connection you will be using, will the Tx/Rx signal be in the GHz range ?

    The bandwidth of the ADG715 IC is 155 MHz, therefore any frequency > 155 MHz will be attenuated if passed through the ADG715 switch.

    The ADG772 is designed to as a general purpose switch that can be routed for USB 2.0 signals, however you are limited to two channels. If it is a USB 2.0 serial connection you are using ?Would it be possible to provide some more details on this ? See link below:

    Please let me know your thoughts ?
