Maxim quad deserializer for ADAS

The MAX9286 quad deserializer from Maxim enables the design of surround-view systems for ADAS.

One MAX9286 gigabit multimedia serial link (GMSL) deserializer receives and automatically synchronizes video from up to four cameras.

Surround view systems are a key component in today’s emerging ADAS market. The MAX9286 automotive deserializer accepts and synchronizes video streams from four cameras via a shielded twisted-pair (STP) or coaxial cable by up to 15 meters.

The MAX9286 outputs the data via a four-lane, industry-standard CSI-2 interface to a video processor.

It reduces board space and component count by replacing four discrete deserializers and an FPGA.

Inaddition, the deserializer eliminates additional software required for camera synchronization.

The MAX9286 is suitable for machine vision and 3D-camera systems.
