Fastest SPI for ZCU102

Hello,

 

I was wondering what the maximum baud rate for SPI is for the ZCU102. I see in Vivado that based on the three different clocks the maximum rate is 200 MHz for the SPI controller on the PS. Can I increase this? What is the maximum?

Would using a separate SPI IP in the PL allow for higher clock speeds? How high?

 

I appreciate the help. Thanks.

I don't know max baud rate for the SPI controller on the PS.  However, SPI in the PL will support much higher rates (up to 1600 Mb/s)!  Check out the IP called "High Speed SelectIO" for UltraScale devices that is described in PG188.

If you want to roll-your-own (instead of using IP), then search the Forum for "source-synchronous input/output", especially posts by avrumw about this topic.

Cheers,
Mark
