A-PHY supports two noise/performance profiles (P1 and P2), with full inter-profile interoperability, as shown in the table below:

  • Profile 1 (P1): Optimized for low cost/power implementations for the lower speed gears with lower noise immunity and target BER of <10-12
  • Profile 2 (P2): Optimized for the vehicle lifespan, with link robustness for all speed gears with high noise immunity and target PER of <10-19. All gears working in Profile 2 are tuned for performance and high noise immunity.
