Description

This reference design provides a compact and scalable camera module for automotive driver monitoring systems (DMS) and other vision applications. It combines a 2-megapixel (2 MP) imager with a 4-Gbps serializer and four-channel power management integrated circuit (PMIC).The camera module is a two-board design to illustrate the flexibility and scalability of the power and serializer components to different image sensors: depending on the ADAS application. The 4-Gbps serializer incorporates FPD-Link III SerDes technology: enabling the transmission of uncompressed video data remotely to a display or machine vision processing system. Bidirectional control signals and power-over-coaxial (POC) can also be transmitted to the camera module with a single cable.The camera PMIC enables a compact design optimized for flexibility and thermal performance by integrating three buck converters and one low-dropout regulator (LDO) with programmable output voltages and sequencing. Supervisors are integrated on each rail to further reduce the component count and overall form factor.
