Part Number: SN65C1167

Hello team , my customer wants to implement below architecture based on the article http://www.ti.com/lit/an/slyt441/slyt441.pdf

The query is :

is the below use case fine for 4Mhz data rate of SPI 

Also application note talks about using Two SPI to take care the delay but customer thinks his speed being low that might not be required .

Can you please look into the same .

    Shreenidhi,

    Yes, 4MHz SPI should work for this application. Please make sure the parallel wires have same length and put termination on both ends of the transmission. I also agree you don't need to have the second one for delay compensation. Please let me know if you see any issues (like timing) in application.

    Regards,
    Hao
