Texas Instruments Incorporated today introduced the DS90UB913Q serializer and DS90UB914Q deserializer, the newest additions to its FPD-Link III automotive-grade chipset family. The SerDes chipset provides 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.

Key features and benefits of the DS90UB913Q and DS90UB914Q:
•Smallest serializer for ultra-compact megapixel camera modules: DS90UB913Q features 25-mm2 footprint, with 10-MHz to 100-MHz pixel clock and 10- and 12-bit pixel depth.
•Industry’s first adaptive receiver EQ compensates cable loss: DS90UB914Q automatically adapts EQ gain, compensating for dynamic and long-term changes in cable loss.
•Fast response time increases driver safety: Continuous, bidirectional control channel on a single twisted pair cable provides low latency for precise multi-camera synchronization.
•Lower-cost cable assemblies: Lower serial line rates of up to 1.4 Gbps drive down system costs.
•System flexibility: DS90UB914Q’s integrated 2:1 multiplexer allows the ECU video processor to select content from two camera sources.
•Supports heat-exposed installations: The SerDes chipset operates over the -40 degrees C to 105 degrees C temperature range.

The DS90UB913Q and DS90UB914Q can be combined with other automotive vision control building blocks, including the TMS320DM8148 (DM8148) automotive vision processor; LM22671 42-V, 500-mA SIMPLE SWITCHER step-down voltage regulator; and LP38693 500-mA LDO regulator.

Tools and support
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. Engineers designing with this SerDes chipset can ask questions and get answers from TI experts in the TI E2E Community High Speed Interface Forum.

Availability, packaging and pricing
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.
