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.
