WebSPI bus at 50MHz can easily run a couple of inches thru a few vias without hitch. Wavelength of 50MHz is 6 metres but realistically because fast edges are used you need to think ten times faster. Even so that's a wavelength of 60 cm. Rule of thumb is keep tracks smaller than a half of a quarter wavelength (other folk will use other rules of ... WebJul 17, 2024 · SPI Bus Impedance. Hi guys, i am going to connect 2 STM32 via 3 SPI busses for high speed data transfer throughput (STM32H7 <-> STM32G4). The STM32G4 will be Master and the SCLK-frequency will be 84MHz - i will use the associated pins in the highest speed mode setting. I am having an extremely hard time to find any information about … Web6 Signal Routing Guidelines Customers are recommended to meet or beat the following signal routing recommendations below: All length/mismatch guidelines are provided in inches.

WebUse small value series resistors near the drive source for each spi line. 10-20 ohms. 1 techcaleb • 3 yr. ago For I2C, make sure you have pull up resistors right next to every endpoint, run the two pairs together so they are roughly the same length, and keep them away from high frequency signals. WebIf needed, slow down the digital interface on the ADC (usually SPI or I2C) with an RC circuit (for inputs) or series resistor (for outputs); see the routing guidelines below for more details; The first point to look at is placement and routing, followed by grounding. The correct grounding design will support noise suppression in your routing.
