Description
The VS6663 is a camera designed for use across
a wide range of mobile phone handsets and
accessories. It is designed to be used for high
quality still camera function and also supports
video modes. The camera silicon device is
capable of generating raw Bayer 1.3 Mpixel
images up to 30 fps. The VS6663 supports the
CCI control and CCP2 and CSI-2 data interfaces.
The module design is optimized for both footprint
and height. The lens element provides excellent
image quality at focus distances from 60 cm to
infinity.
A separate hardware accelerator can be
incorporated in the phone system to run the
algorithms in hardware. The specification of these
devices are contained in a separate document.

VS6663 diode, scr
VS6663
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 VS6663 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 VS6663 supplies the high-speed data qualification clock for the
coprocessor. The high-speed clock is generated using the VS6663 embedded PLL and is
provided as the continuous data qualification clock.
1.2 VS6663 use in a system with software image processing
The VS6663 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.

Power-off
The power-off state is defined as either or both of the digital and analog supplies not
present.
Hardware standby
This is the lowest power consumption mode. CCI communications are not supported in this
mode. The PLL and the video blocks are powered down. This state is entered by pulling the
control pin XSHUTDOWN down (active low). All registers are returned to their default values
Software standby
Software standby mode preserves the contents of the CCI register map. CCI
communications are supported in this mode. The software standby mode is selected using a
serial interface command. If this state is entered from hardware standby the data pads
remain high impedance. If this state is entered from streaming then the data pads go high
impedance at the end of the current frame. The internal video timing is reset to the start of a
video frame in preparation for the enabling of active video. The values of the serial interface
registers like exposure and gain are preserved. The system clock must remain active when
communicating with the sensor.
This state is entered by releasing the device from hard reset by setting XSHUTDOWN high,
writing 0x00 to the mode control register (0x0100) or commanding a soft reset by writing
0x01 to the software reset register (0x0103).
After a soft reset or the transition of XSHUTDOWN to high, all registers are returned to their
default values.
Streaming
The VS6663 streams live video. This mode is entered by writing 0x01 to the mode control
register (0x0100).
Dark calibration algorithm
VS6663 runs an automatic dark calibration algorithm on the raw image data to control the
video offsets caused by dark current. This ensures that a high quality image is output over a
range of operating conditions. First frame dark level is correctly calibrated, for subsequent
frames the adjustment of the dark level is damped by a leaky integrator function to avoid
possible frame to frame flicker.
