SPI SCK Clock Frequency MAX 80/33.3 MHz

Theoretical Guaranteed Speed

Even though theoretical design speed is 80MHz, the signal in the high speed may be distorted because of the circuit crosstalk and the length of the signal line. The minimum guaranteed speed of the SCLK is 33.3 MHz which was tested and measured with the stable waveform.

Please refer to the SPI Application Note which shows the WIZnet test environment and results.

也就是说推荐最高33.3MHz。

具体请参考数据手册。

PC就那几种接口，如果非要用SPI的话，需要自己做板卡通过PCI/PCIE插槽实现。建议采用USB方式，速度比较快。
