Joint reference design from OmniVision and Leopard accelerates time to market for rearview and surround-view camera systems
Surround view and real-time cameras are increasingly being adopted by automakers to offer safer and more advanced vehicles to consumers. OmniVision and Leopard have created a new reference design that meets the design requirements of automotive rearview cameras or surround-view cameras, such as small size, low power consumption, low thermal output, and image quality.
Compact Automotive HD Viewing Camera Module Design Fits on Single PCB
OmniVision Technologies has unveiled its high definition (HD) automotive camera module reference design, developed with collaboration from Leopard Imaging and featuring technology from Texas Instruments (TI). The compact design includes OmniVision’s OX01B40 image sensor plus image signal processor (ISP) system-in-package (SiP), as well as TI’s DS90UB933-Q1 or DS90UB935-Q1 serializer chip and TPS65000-Q1 power management integrated circuit (PMIC).
The design is claimed by the companies as the automotive industry’s first HD camera module to fit all its components on a single PCB, including the OmniVision OX01B40 image sensor plus image signal processor system-in-package.
All four components are AEC-Q100 Grade 2 qualified, with an operating range of -40 to +105 degrees Celsius.
The reference design can be integrated directly into vehicles as a low-cost solution with the fastest time to market, or the design can serve as a starter kit for Tier-1s and OEMs who want to create their own camera modules, the announcement stated.
“As the transition from analog to HD digital cameras in automotive applications moves into the mainstream, our joint reference design meets the need for cameras that are as small and unobtrusive as possible while providing accurate images in all lighting conditions,” said Bill Pu, President at Leopard Imaging. “The compact, low-power components from TI and OmniVision allowed us to achieve our goal of a single-board design.”
OmniVision’s OX01B40 SiP combines a high-performance 1392 x 976-resolution color CMOS image sensor and an ISP. It supports streaming video of up to 60 frames per second (fps) and consumes less than 400 mW of power.
Built on OmniVision’s 2.8-micron OmniBSI-2 Deep Well pixel technology, the OX01B40 delivers best-in-class low-light sensitivity and 120 dB high dynamic range (HDR) performance for excellent contrast and for resilience to rapidly changing lighting conditions ranging from darkness to bright sunlight, claims the company.
“The OX01B40 is perfectly suited for this application,” said Andy Hanvey, director of automotive marketing at OmniVision. “Because of its small size and industry-leading low power consumption, it can enable smaller camera modules with lower thermal output, and its HDR minimizes motion artifacts.”
Handling the power needs in the design, TI’s TPS65000-Q1 single-chip PMIC combines low-dropout regulators with a step-down converter that can operate in forced PWM mode or auto PWM-PFM mode, depending on load, to maximize efficiency.
“Through this design, automotive engineers can quickly take advantage of the combined knowledge and expertise from OmniVision, Leopard and TI to implement cost-effective, high-performance viewing cameras,” said Hannes Estl, general manager of automotive ADAS at TI. “TI’s power supply and serializer chips enable the high density and small solution size that help realize this very compact 1-MP camera module design.”
