OmniVision Technologies, Inc. has released
its high-definition (HD) automotive camera module reference design, developed
in partnership with Leopard Imaging. The single-board design includes OmniVision’s OX01B40 image
sensor and image signal processor (ISP) system-in-package (SiP), as well as Texas Instruments’ DS90UB933-Q1 or DS90UB935-Q1 serializer chip and TPS65000-Q1 power management
integrated circuit (PMIC). The reference design helps developers design
automotive viewing cameras particularly for rearview cameras and surround-view
cameras.
 

All four components are AEC-Q100 Grade 2-qualified and
operate over a temperature range of –40°C to 105°C. OmniVision said that the
reference design can be integrated directly into vehicles as a low-cost solution
with a fast time to market or it can be used as a starter kit for Tier-1
suppliers and OEMs that want to create their own camera modules.

“This is the first automotive camera module to
incorporate all of its components on a single printed circuit board (PCB),”
according to OmniVision. “Existing modules stack at least two PCBs for the
image sensor and ISP, respectively, and usually a third for the power ICs.”

 

Key features of the OX01B40 SiP:

  • Built on OmniVision’s 2.8-micron OmniBSI-2 Deep Well
    pixel technology
  • Combines a 1,392 × 976-resolution color CMOS image
    sensor and an ISP
  • Supports streaming video of up to 60 frames per second
    (fps)
  • Consumes less than 400 mW of power

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,” said OmniVision.
 

On the power side, TI’s TPS65000-Q1 single-chip PMIC combines low-dropout regulators
with a step-down converter. The chip can operate in forced PWM mode or auto
PWM-PFM mode, depending on load, to maximize efficiency, said the company.

Designers get a choice of either parallel CMOS (DS90UB933-Q1) or MIPI CSI-2 (DS90UB935-Q1FPD-Link serializers, which support communication with high-speed
image sensors. Both options target high-resolution, compact camera module
designs with 1-MP cameras streaming at up to 60 fps. In addition, the DS90UB935-Q1 eliminates the need for an oscillator in the
camera module, said OmniVision, saving space and cost.
