Innovation of Smart Driving Chip

R-LinC is a high-speed SerDes IC designed for auto industry to simplify the high-speed audio and video signal transmission used for in-vehicle cameras and monitors. R-LinC is manufactured with 22nm process and supports up to 16Gbps over a distance of 15 

meters on a single coaxial cable with adaptive equalization. It is fully compatible with

data rates ranging from 1.6Gbps to 16Gbps.

  • Support forward channel data rates up to 16Gbps and backward compatible to 1.6Gbps, offering more flexible options;
    Support reverse channel with 200Mbps or 100Mbps data rates.
  • Support adaptive equalization, highly adaptive to channel environmental changes;
    Support design with coaxial （15m） or twisted pair （10m） cables;
    Support Multiple Spread Spectrum scheme for EMC mitigation;
    Support FEC (forward error correction) and retransmission, improve BER and system stability;
    ASIL-B functional safety
    AECQ-100 Grade2
  • Highly integrated: Dual MIPI ports in Serilizer, and 6 R-LinC aggregation in Desserilizer, support up to 12x 8MP cameras;
    C/D PHY: Advanced C/D PHY capabilities include D-PHY at 2.5Gbps per lane and C-PHY at 5.7Gbps per trio;
    Multiple interface support: surpport I2C, UART, SPI, and GPIO etc...

The Importance of Self-Adaptive
  • AEQ can adjust coefficients in real-time based on the changes of transmittion channel characteristics, mitigate inter symbol interference, and improve signal quality.
  • When vehicle is on road, vibrations or oscillations generated by modules, wiring harnesses, and connectors will affect the transmission channel parameters thus change the channel characteristics.
  • Aging of the wiring harness also affect the transmission channel and change the channel characteristics.
    • The Importance of Insertion Loss
  • Insertion loss is one of the most important parameters to measure the quality of signal propagation.

    The higher the insertion loss compensation capability, the better the signal transmission quality.
    • Camera Application – In-Vehicle Assistance
