Automotive HD camera module reference design measures 23x23x25mm

September 18, 2018 // By Julien Happich
Developed in cooperation with Leopard Imaging, the high definition (HD) automotive camera module reference design announced by OmniVision Technologies is only 23x23x25mm.

Fitting on a single PCB, the kit 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). 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

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 new reference design was created to assist customers in designing automotive viewing cameras, especially rearview cameras or surround-view cameras, where small size, low power consumption, low thermal output, and excellent image quality are critical. This is the first automotive camera module to incorporate all its components on a single printed circuit board (PCB). Existing modules stack at least two PCBs for the image sensor and ISP, respectively, and usually a third for the power ICs.

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. This reference design also offers the choice of either parallel CMOS (DS90UB933-Q1) or MIPI CSI-2 (DS90UB935-Q1) FPD-Link serializers, both of which support communication with high-speed image sensors and are for customers designing high-resolution, compact camera modules with 1-MP cameras streaming at up to 60 fps.
