Automotive HD Link (AHL) technology from Renesas and OmniVision’s OX01F10 SoC are used in an integrated reference design for automotive camera systems. The two companies have developed the reference design in which AHL technology transmits HD video over low-cost cables and connectors. The AHL components pair with OmniVision’s OX01F10 1.3MP SoC, which is claimed to provide the industry’s best imaging performance across a wide range of challenging lighting conditions. It is also compact and has low power consumption, said OmniVison.

The new RAA279971 AHL encoder and RAA279972 decoder use a modulated analogue signal to transmit the video, enabling transmission rates 10 times less than required to transmit HD signals digitally. The lower transmission rate means that unshielded twisted pair (UTP) cables and standard low-cost connectors can be used, as can existing traditional analogue video cables and connectors.

Renesas added that AHL can be paired with other Renesas products, such as the R-Car Automotive SoCs, RH850 MCUs, automotive PMICs, and analogue components to implement numerous safety features in virtually any vehicle.

OmniVision’s OX01F10 SoC integrates a 3.0 micron image sensor and an image signal processor (ISP) with OmniVision’s PureCel Plus technology for low noise, solving the automotive rear view camera and surround view system challenges of achieving a small form factor with low-light performance, low power and reduced cost while improving reliability by enabling single PCB designs.

The 1.3MP OX01F10 supports HDR up to 120dB and the sensor features ASIL-B.

The reference design will be demonstrated at OmniVision’s booth #15 at AutoSens Brussels 2021 Exhibition, September 15 to 16.

The reference design is available through both Renesas and OmniVision.

Infineon Technologies and Robert Bosch have collaborated to develop a low loss diode to reduce CO² emissions in light vehicle generators.

The Active Rectifying diode enables an increase in generator efficiency of up to eight per cent compared to conventional power conversion methods, says Infineon. Deploying the diode can reduce the CO² emissions of a car by up to 1.8g/km. It can replace standard devices for use in generators and cars that are already in series production. It is a quick and cost-efficient step for OEMs to reduce fleet emission targets, said Finn Felsberg, vice president and general manager, power integration and supply at Infineon’s automotive division

In a conventional car, the generator produces the electric energy for charging the battery and supplying a growing number of safety and comfort features such as driver assistance systems, air conditioning and infotainment. The Active Rectifying diode allows generators to achieve a power conversion efficiency beyond 80 per cent, compared with typical levels of up to 72 per cent today, said Infineon.

The Active Rectifying diode is based on Infineon’s chip technology which integrates MOSFETs, capacitors and control logic on a single die. The chip is assembled by Bosch into the body of the diode in a pressfit package. The diode is distinguished by a low diode forward voltage of 0.1V at 100A RMS and a low leakage current. It also  features mechanical robustness as well as high reliability and EMC, with a simple assembly process.

The Active Rectifying diode is in production at Bosch.
