TMS320F28377S: SPI hardware circuit/layout guide for TMS320F28377S

Hardy Zhou

Part Number: TMS320F28377S

My customer will plan to use SPI for two TMS320F28377S communication at 50MHz clock speed,

do we have any hardware circuit / layout guide for about 20cm distance design between two TMS320F28377S？

Thanks

    Hardy,

    When routing high speed signals you should have a continuous ground plane (without breaks or channels) directly above or below the signal trace. Such controlled impedance provides clean current return path to ground.
