CMOS image sensor breaks into camera market
According to OmniVision Technologies, the OV5610 5Mpixel camera chip has already achieved eight design wins in digital still camera and video camera markets.
This true single-chip solution can be used in numerous automotive driver assistance applications.
"The automotive market is an important growth market for image sensors, with cameras fast becoming a standard feature on new cars", commented Hasan Gadjali, Director of Marketing for Advanced Products at OmniVision.
"We are ready to provide Tier 1 manufacturers with a premium quality yet cost-competitive module solution with the OV7940, which, because of its optimised single-chip design, will enable a module cost of under US $30.00".
Market analyst firm Techno Systems Research (TSR) projects that application volumes for CMOS image sensors will surpass those for CCD sensors next year, and that by 2008, 20 million CMOS sensors will be in use in the automotive market.
The OV7940 is built to stringent, high end specifications that meet the Automobile Electronics Council AEC-Q100 criteria encompassing a series of tests including, but not limited to, preconditioning, humidity, high temperature cycle, mechanical, optical and electrical test parameters.
For example, it uses a 48-pin quad flatpack (QFP) arrangement that firmly attaches the sensor to the PCB, enabling it to withstand both severe vibration, and expansion and contraction in extreme temperatures.
Its OmniPixel technology design has an extended operational temperature range of -40 to +85C and its high sensitivity makes it well suited for low light conditions.
Both of these factors are critical requirements in automotive applications.
In addition to a number of key applications in the automotive market, the OV7940 is also suitable for applications where high-performance image sensors are important, for example, in mainstream CCTV and security systems, currently dominated by CCDs.
Besides the colour OV7940, a black-and-white version, the OV7440, is also available.
Both devices support the NTSC and Pal formats.
These devices are available for sampling now and are expected to be in volume production in the third quarter of 2005.
