The module design is optimized to provide an ultra
small footprint and height, and is designed to be
reflowable at lead-free solder profiles. The product
is lead free.
The lens design is optimized for video conferen-
cing and maintains its performance even after the
high temperatures of lead-free reflow.
VS6451 offers an ultra low power consumption
hardware standby mode consuming less than
30 µW.
Description
This VS6451 is an ultra small reflowable CIF+
camera module for use across a range of mobile
phone handsets and accessories. It is primarily
designed to be used as a second camera in video
conferencing applications, but it may also be used
as a primary camera. The camera sensor is SMIA
class 2 profile 0 compliant and is capable of
generating raw bayer CIF+ images up to 30 fps.
The VS6451 supports the CCI control and
CCP2.0 data interfaces.
As different phone platforms have different
baseband processors with varying capabilities, it
may not be possible for all phones to support the
associated image processing algorithms. Where
the baseband cannot support this processing
load, a separate hardware accelerator (STV0976
or STV0984) device can be incorporated in the
phone system to run the algorithms in hardware.
The STV0984 processor can support 2 cameras.
The specifications of these devices are contained
in a separate document.
