WebJul 24, 2024 · The allowed deviation in length matching depends on the rise/fall time for digital signals between these two elements, although it is generally recommended that any deviation be less than 10 mm as MII and RMII use TTL logic. Again, the allowed trace length mismatch depends on the rise/fall time of digital signals. WebSome quad SPI config flash run at 100 MHz. Of course, this applies to any other SPI chips. Quad or not. But be careful of the limitations of choosing a high speed, both in PCB layout (noise, length matching) and firmware/ software (buffers, delays, etc). SPI is considered a "low speed" protocol. In most cases, 1 or 10 MHz should be enough.
