6 Compatibility with G9V/Q/X

This power supply design is also compatible with Semidrive G9V, G9Q, and G9X. The difference between the platforms is the number of physical layers (PHY). Since the power design is pin-to-pin compatible between the different platforms, the same ICs can be used to lessen re-design effort.

RTC and safety power supply for both MCUs are the same, so the same power trees for G9H shown in the Power Design section can be reused for the G9 series in powering G9V/G9Q/G9X.
