SerDes Chipset streamlines video and data interface for driver assist cameras

August 16, 2012 // By Nick Flaherty
Texas Instruments has launched a SerDes chipset that combines the industry’s smallest footprint with system-level enhancements to drive camera safety systems into mid- and entry-level vehicles

The DS90UB913Q serializer and DS90UB914Q deserializer, the newest additions to its FPD-Link III automotive-grade chipset family, provide a seamless video and data interface to megapixel driver assist camera modules, with no software overhead and fewer wires, resulting in reduced power consumption, cost and weight.
These system-level SerDes enhancements are accelerating the adoption of camera safety systems in the mid- and entry-level vehicle segments. Applications include front-view camera for collision avoidance and traffic sign/pedestrian recognition, rear-view camera for backup protection, and surround-view cameras for parking assistance.
Camera systems have become an important automotive safety component, typically combining multiple camera modules with advanced image analysis to help drivers monitor road conditions, detect hazards and avoid collisions. Automotive safety system designers can use TI’s FPD-Link III SerDes chipsets to connect cameras and displays to an electronic control unit (ECU) with thinner, more flexible cabling.
The DS90UB913Q is the smallest serializer for ultra-compact megapixel camera modules with a 25-mm2 footprint, with 10-MHz to 100-MHz pixel clock and 10- and 12-bit pixel depth. The DS90UB914Q automatically adapts EQ gain, compensating for dynamic and long-term changes in cable loss.
Both provide continuous, bidirectional control channel on a single twisted pair cable provides low latency for precise multi-camera synchronization with lower serial line rates of up to 1.4 Gbps to drive down system costs and the DS90UB914Q’s integrated 2:1 multiplexer allows the ECU video processor to select content from two camera sources
The DS90UB913Q serializer and DS90UB914Q deserializer are supported by the SERDESUB-913ROS evaluation kit. It is available today for a suggested retail price of US$399. IBIS models for the DS90UB913Q and DS90UB914Q are also available.
The DS90UB913Q and DS90UB914Q are available now for a suggested retail price of US$5.36 for each device in 1,000-unit quantities. The DS90UB913Q serializer is supplied in a 32-pin, 5-mm x 5-mm QFN package, while the DS90UB914Q deserializer is offered in a 48-pin, 7-mm x 7-mm QFN package.
