Motion Control Bus
Everest CORE can be controlled as a slave by means of its proprietary Motion Control Bus (MCB). Check how in the Summit Series Reference Manual.
MCB Layout is critical
Note, the high-speed MCB signals (MCB_SPI_MOSI, MCB_SPI_MISO, MCB_SPI_CLK) must be routed with care. Not following the best high speed layout practices will result in communication problems and loss of data. Please:
Do not ever route these signals close to the motor phases or switching nodes of DC/DCs. Keep a safe > 15 mm distance to switching noise.
Ensure they have a good GND return on all its length on the PCB. Route them as strip lines, if possible microstrip for longer distances is also recommended.
Keep line impedances between 60 Ω and 150 Ω.
Avoid T stubs and acute angles.
Minimize crosstalk to other signals by reducing parallel coupled length.
Consider adding 0 Ω ~ 47 Ω series termination resistors at the end of the fast lines as a provision to minimize reflections in case communication issues arise.
