This reference design provides a compact and scalable camera module for automotive camera applications. It combines a 2.9-megapixel (2.9-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. 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.
