NBIC is part of the A-PHY specification. An application note has been created by the A-PHY working group to define a noise profile for the various noise sources in the system. The noise profile has been used by multiple companies to validate and test possible solutions.
EMC requirements vary by OEM. Some aim for minimal noise immunity, while others apply stringent requirements to protect their systems.
The two A-PHY performance profiles provide two noise immunity levels to accommodate this variance:
All the communication link requirements are covered within the A-PHY specification (e.g., return loss, insertion loss, etc.). There is a clear definition for the channel, with the parameters required to design transmitters and end receivers for MIPI A-PHY.
Note: A channel model for simulation is available that can be used by MIPI members for validation.
