Do we have a signal conditioner for SPI bus?

Other Parts Discussed in Thread: SN74LVC125A, SN74AUC125

Hi team,

My customer is consulting if TI has a suitable solution like a signal conditioner for SPI bus? such as a redriver/buffer/drive etc. 

They just mention to me their trace length is concerning and want to have a redriver in consideration of the signal quality.

Do you have a part number in mind that could propose to me please?

Thanks

Max

    Max,

    Our group has several devices with SPI integrated for configuration and control of the transceiver, but no specific SPI redriver devices unfortunately.

    We have a TI Design that uses CAN to extend the length of I2C signals which can be found here. This might be a bit overkill for what you're asking, but it may be helpful to give ideas.

    Please let me know if you have any other questions.

    Regards,

    Eric Hackett

    SPI uses logic-level signals, so in most cases, you would simply use a logic buffer, something like SN74AUC125 or SN74LVC125A, depending on the voltage, and with the appropriate number of channels.
