I am trying to implement and use the intel generic quad spi controller II to communicate with a serial flash memory.
The user guide states that the clock connection has a maximum frequency of 40 MHz.
Is that correct and why is that?
The rest of my design is running at 64 MHz and that is the frequency I would like to run the SPI core.
If the maximum clock rate really is 40 MHz then I believe I will have to implement a clock crossing bridge.
Thanks for any info you can provide.
Yes correct. According to the user guide it is designed to work up till 40MHz only. Whereas for the reason why the maximum input clock is 40MHz, I will have to ask engineering team to look into deeply.
