Abstract

This disclosure describes techniques for improved routing of high speed C-PHY signal traces and the placement of power conversion components on a logic board of a camera system. Per techniques of this disclosure, low frequency power supply noise coupling into high speed MIPI C-PHY signals is reduced or eliminated by placing the power converter components at a minimum distance from the MIPI C-PHY high speed channels. Additionally, the ground (GND) return of the power supplies is improved for better noise reduction. In some implementations, the wide (high frequency) and ultra-wide (low frequency) channels are swapped. The low frequency coupled noise can be eliminated by the routing described herein.
