Surround-View Camera

Surround-view cameras are key components in many Advanced Driver Assistance Systems (ADAS), giving a bird’s-eye view of a vehicle’s surroundings, which improves occupant safety and enables autonomous driving. Examples of ADAS applications that utilize surround-view cameras include lane departure, parking assist, blind side detection, pedestrian detection and adaptive cruise control.

One of the critical components of an effective surround-view camera system is high-speed connectivity. Microchip offers automotive-grade Ethernet devices and INICnet™ controllers for use in transferring video, data and messages on various forms of media. Solutions for control, diagnostics, power management, timing and security are also provided by Microchip, enabling a complete system design for future generations of surround-view camera systems utilized in ADAS.
