VX6854LC
QXGA EDOF camera module
Datasheet - production data
Description
The VX6854LC 3 megapixel camera module is
designed to be used for high quality still camera
function and also supports video modes. The
camera silicon device is SMIA 1.0 profile 2
compliant and is capable of generating raw bayer
3 Mpixel images up to 20 fps. The VX6854LC
supports the CCI control and CCP 2.0 and CSI-2
data interfaces.
The module design is optimized for both footprint
and height. The module provides excellent image
quality at focus distances from less than 50 cm to
infinity.
Features
• 3.15 megapixel resolution sensor (2048 x1536)
• Extended Depth of Field (EDOF)
• Compact size: 6.5 x 6.5 x 4.6mm
• SMIA Profile 2 compliant
• MIPI(a) CSI-2 (v0.9 D-PHY) and SMIA CCP2
video data interface
• CCI command interface 100 KHz up to
400 KHz
• 2.8V (analog) / 1.8V (digital) operation
• Integral EMC shielding
• Binning mode (2x2)
• Defect correction
• 4-channel lens shading correction
VX6854LC offers an ultra low power consumption
hardware standby mode consuming less than
50 μW (typical).
A separate hardware accelerator (STV0987)
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.

VX6854LC
1 Overview
Overview
The VX6854LC image sensor produces raw 3.15 Mpixel digital video data at up to 20
frames per second.
The VX6854LC has both CCP2.0 and MIPI CSI-2 video data interfaces selectable over the
Camera Control Interface (CCI). The VX6854LC is compliant with the SMIA 1.0(b)
Specification Profile 2. The VX6854LC can also be used as Profile 0 or Profile 1 device. The
sensor supports full horizontal and vertical scaling and output frequency derating as defined
in the specification. The VX6854LC supports 2x2 binning modes which support frame rates
of 40 fps and 80 fps respectively.
The image data is digitized using an internal 10-bit column ADC. The resulting pixel data is
output as 8-bit, 10-bit or 10-8 bit compressed data and includes checksums and embedded
codes for synchronization. The interface conforms to both the CCP 2.0 and MIPI CSI-2
interface standards. The sensor is fully configurable through a CCI serial interface.
The module is available in a SMOP type package measuring 6.5 mm x 6.5 mm x 4.6 mm. It
is designed to be used with a board mounted SMIA65 socket.
