Description
This data brief outlines a high performance
3.15 megapixel EDOF camera module (VX6852)
for use across a range of mobile phone handsets
and accessories. It is designed to be used for high
quality still camera functions and also supports
low power video modes. The product can output
raw bayer 3 Mpixel images at up to 20 fps.
The module design is optimized for both footprint
and height. The module is always in focus from
30 cm to infinity. All components are integrated
inside the camera module, with the exception of
two CCI pull-up resistors and a de-coupling
capacitor.
VX6852 offers an ultra low power consumption
hardware standby mode consuming less than
30 µW (typ.).

Data Brief
A separate hardware accelerator (STV0986) or
application engine (STn8815) device can be
incorporated in the phone system to run the
associated image processing algorithms in
hardware where the baseband cannot support
this processing load. The specifications of these
devices are contained in a separate document.
