Part Number: SN65LVDS33

Hi team,

My customer would like to build a SPI buffer solution with our SN65LVDS33 which has mentioned in TIDA-060017.

And, there is also a application note which is talking about SPI buffer for long distance communication as below link.

Extending the SPI bus for long-distance communication

Which one is more suggestion from your view? Which can support long transmission distance?

Thank for your kindly support.

    One is a app note and the other is a reference design, you can use both for the SPI over LVDS design.

    Thanks

    Hi David,

    Thanks.Customer still want to know below questions.

    How do we get the delay time as below figure in TIDA-060017 such as ADS8910B, SN65LVDS33 ?

    In this design, it seems doesn't mention about the delay time at host. Is there any special reason?

    Please refer to step 1 in tiducm5a design guide for the delay calculation: http://www.ti.com/lit/ug/tiducm5a/tiducm5a.pdf.
