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.
