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.
