Automotive deserializer IC integrates four surround view camera streams
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, reducing board space and component count by replacing four discrete deserializers and an FPGA.
In addition, this highly integrated chip eliminates additional software required for camera synchronization. Developers of machine vision and 3D camera systems can also benefit from the new device.
Key features include:
• Shortened design time: lower design risk and time to market with automatic generation of camera synchronization signals, alignment of image data from multiple sensors to the same pixel, and user programmability of key parameters.
• Lower cost: integration reduces board space and component count by eliminating four discrete deserializers and an FPGA. It also supports power over coaxial cabling to reduce wiring and cost.
• Diagnostic capability: enhanced system integrity with on-chip diagnostics for link bit error rate (BER), detection of camera falling out of sync, or cable shorts to power/ground.
"The need for surround view capability in the automotive market poses unique challenges in ADAS designs," said Balagopal Mayampurath, Director of Business Management at Maxim Integrated. "This product simplifies first generation surround view system design and enables a seamless transition to next-generation systems."
