REFERENCE GUIDE

Automotive 8.3-MP POC Camera Module Reference Design with PMIC and FPD-Link III

Description

This camera module reference design addresses the need for small low-cost cameras in automotive driver assistance systems (ADAS) by combining a 8.3-megapixel imager with a 4.16-Gbps TI FPD-Link III serializer. Additionally, it provides a power-management integrated circuit (PMIC) power supply for both devices in an ultra-small form factor. This design includes a high-speed serial interface to connect a remote automotive camera module to a display or machine vision processing system with a single coaxial cable transmitting both 8.3-MP RAW12 HDR video data and power.
