Detailed Design Procedure

The interface design requirements are fairly straight forward in this single source/destination scenario. Trace lengths and cable lengths need to be matched to maximize SPI timing. If there is a benefit to put the interface to sleep, GPIOs can be used to control the enable signals of the transmitter and receiver. If GPIOs are not available, or constant uptime needed, both the enables on transmit and receive can be hard tied enabled. The link shown can operate at up to 30 Mbps, well within the capability of most SPI links.
