OmniVision claims first 1/4-inch Mega Pixel sensor with MDDI interface

OmniVision Technologies, Inc. announced the launch of the
OV3647, the world's first 1/4-inch, 3 MegaPixel image sensor that
supports the mobile display digital interface (MDDI), a high speed serial
interface promoted by QUALCOMM, Incorporated for use with its chipsets.
The OV3647 uses OmniVision's proprietary 1.75 micron OmniPixel3
technology, and has been designed to optimize partitioning with
QUALCOMM's chipsets, offering customers greater levels of system
integration and performance, as well as reducing overall system
cost.

The OV3647 is also
equipped with a standard parallel interface which has the unique ability
to act as an input for a secondary camera, so it can share the MDDI
interface while also functioning as an MDDI hub. Sharing the MDDI reduces
the number of interconnects to the Baseband processor, which increases
reliability, reduces power consumption and enables rapid two-way data
transfer. Sharing the MDDI also eliminates high frequency
electro-magnetic interference
(EMI)
issues, which often have adverse effects on system
performance.

“By optimizing our new
generation, 3 MegaPixel image sensor for QUALCOMM's chipsets, we believe
we will open up additional markets for our products. In fact, we have
already demonstrated the potential by securing a major design win with a
leading smart phone maker,” said Per Rosdahl, director of marketing at
OmniVision.

The OV3647 has a 3
MegaPixel image array, capable of operating at up to 15 frames per second
(fps) in QXGA (2048 x 1536) resolution, with complete user control over
image quality, format and output data transfer. All required programming
functions are accessible via the SCCB interface or MDDI
interface.

The OV3647 uses
OmniVision's proprietary OmniPixel3 sensor technology to improve image
quality by reducing or eliminating common lighting and electrical sources
of image contamination, such as fixed pattern noise (FPN) and smearing,
to produce a clean and fully stable color image.

The OV3647 is small
enough to enable 7 x 7 x 5 mm camera modules with a very short optical
track, and thus is versatile enough to work well both with fixed focus
and auto-focus modules. The OV3647's embedded, one time programmable
(OTP) memory is designed for part recognition and simplification of
module designs using different
lenses.

In addition to targeting
the mobile handset market, the OV3647 is well-suited to applications in
the digital still camera, PC multimedia and toy sectors. The OV3647 is
currently available for sampling, and the company expects to begin volume
production in the third
quarter.
