LCD displays of medium size and resolution (e.g. 10 zoll, W-VGA) can be steered elegantly over a single differential line pair with cable reach of over 10 meters today. Further advantages of such serial concepts (e.g. DS90UR241/124 24 bit single lane Serializer/Deserializer (SerDes)) lies in the simplification of system design with regards to distribution of the video stream over crosspoint switches, signal conditioning for ever longer cable runs or buffering of sensitive components while boosting ESD ruggedness. Typical application include for instance automotive infotainment and driver assistance or security/surveillance camera installations. Through crosspoint switches a single video source can be distributed onto a number of LCD modules (rear-seat entertainment displays). Graphic controllers can be ESD protected through external buffers and profit from signal optimized driver- and receiver performance, greatly enhancing their timing and input amplitude threshold margins. Not at last the performance requirements of the transmission media can be reduced to plain standard twisted pair cabling directly addressing system cost assessment. The combination of these new components' functions and high performing physical layer technology enables automotive and industrial display systems to exhibit extreme robustness and reliability. The accelerated entrenchment of single lane Serializer-Deserializer solutions in automotive and industrial display and camera applications has enabled a much more flexible distribution, switching, buffering and reconditioning of the serial bit stream throughout the installation. When regarded as a comprehensive package these offerings more and more become a true plug 'n' go system design solution due to their no compromise combination of low wire count, high bandwidth, high ESD, low power, low EMI, ruggedness and flexible deployment.
