VS6663CC
Overview
The module's main function is to convert the viewed scene into a data stream. The
companion processor’s function is to manage the sensor included in the module in order to
produce the best possible pictures given the module's optics and the scene itself. The
companion processor processes the data stream into a form which is easily handled by up
stream mobile baseband or multimedia processor (MMP) chipsets.
The sensor supplies high-speed clock signal to the coprocessor and provides the
embedded control sequences which allow the coprocessor to synchronize with the frame
and line level timings. The coprocessor then performs the color processing on the raw
image data from the sensor before supplying the final image data to the host.
In a coprocessor architecture, a low speed clock (external clock) is sent by the host to both
the VS6663CC and the coprocessor. This is used by the sensor in all phases of operation
and by the coprocessor during the initial stages of system boot up.
During streaming phase, the VS6663CC supplies the high-speed data qualification clock for
the coprocessor. The high-speed clock is generated using the VS6663CC embedded PLL
and is provided as the continuous data qualification clock.

VS6663CC use in a system with software image processing
The VS6663CC image sensor can also be directly connected to a baseband or multimedia
processor. No dedicated coprocessor is used in this configuration. The image processing is
done in software within the baseband processor.
