Renesas, OmniVision unveil reference design for automotive camera system
Renesas and OmniVision Technologies Inc, have introduced an integrated reference design for a high-definition automotive camera system. It is based on Renesas' recently introduced Automotive HD Link (AHL) technology, which transmits high-definition video signals over low-cost cables and connectors. The design's AHL components are used in conjunction with OmniVision's 1.3MP OX01F10 SoC. This is said to offer the industry's best imaging performance in a wide range of challenging lighting conditions, as well as the most compact form factor and lowest power consumption.

Renesas' RAA279971 AHL encoder and RAA279972 decoder use a modulated analogue signal to transmit the video. This allows ten times lower transmission rates than digital transmission of HD signals. Thanks to the lower transmission rate, unshielded twisted pair (UTP) cables and low-cost standard connectors can be used as well as conventional analogue video cables and connectors.

AHL can be combined with other Renesas products such as the R-Car automotive SoCs, RH850 MCUs, automotive PMICs and analogue components to cost-effectively implement numerous safety functions in virtually any vehicle.

OmniVision's OX01F10 SoC integrates a high-performance 3.0-micron image sensor and advanced image signal processor (ISP) with OmniVision's PureCelPlus technology for low noise. The SoC thus promises to solve the challenges of automotive rear-view cameras and surround-view systems. It offers a small form factor with high performance in challenging lighting conditions, ultra-low power consumption and reduced cost while increasing reliability. The key to combining all these features is that the reference design presented provides for a single printed PCB.
