TMUX1102: Please suggest a candidate which can support the switch for SPI CLK.

Part Number: TMUX1102

Hi Sir,

I got a customer they request a candidate which can support the switch for SPI CLK. There are 2 main requirements from them:

1. Support 100Mhz frequency signal

2. The source from S, output to next stage from D...when the switch be cut(open), the request the D need to be high impedance.

3. Due to the application will be used on SPI CLK pin, they need the precision switch.

Would TMUX1102 be suitable candidate for them? If not, please advise.

Thanks,

George

    Hi George,

    Can you provide some more details on how you are planning to use TMUX1102 switch for SPI?

    Do you have a 3 or 4 wire SPI interface and is the SPI operating at 100MHz?

    The TMUX1102 is rated for a Bandwidth of 300 MHz at 5.5V supply. Can you provide me with more information on supply and input voltages?

    if you have a schematic or a diagram of your use case, that will help us to recommend the best switch for your application.

    Thanks
