Bidirectional control

  • 26-Jul-2010 10:37 EDT


National Semiconductor's FPD-Link III family of automotive-grade serializer and deserializer (SerDes) chipsets provide real-time, bidirectional control for driver-assist video cameras. Chipsets improve safety and response time by delivering clock, data, and bidirectional control continuously over a single differential pair. Safety system designers can use the embedded clock SerDes to connect cameras and displays to an ECU with minimal software and reduced wires. Cyclical redundancy monitors data integrity, while back-channel technology delivers communication between remote camera heads and the ECU to synchronize side and rearview cameras and assist drivers with blind spots, lane departure, collision avoidance, and parking. Models are designed for camera systems with 14-bit color depth or support the 18-bit depth needed for in-vehicle infotainment systems. Powered by 1.8 V, chipsets route video content over 10 m (33 ft) and support 10 to 43 MHz with temperature ranges between -40 to +105°C (-40 to +221°F).
