VS6552
VGA Color CMOS Image Sensor Module
FEATURES
■ Small physical size
VS6552 offers an ultra low power standby mode
that consumes less than 15 µW.
The SmOP lens has been designed to combine
class leading low light performance with good
depth of field to ensure excellent overall optical
performance. The lens is a 2 element moulded
plastic design.
The output data and qualification clock are trans-
mitted over low noise, low voltage and fully differ-
ential links. VS6552 configuration registers are
controlled via a private I2C interface to STV0974.

DESCRIPTION
Pixel size
The VS6552 is a VGA resolution SmOP sensor
module. SmOP technology combines the image
sensor and fixed focus lens system in a single
module. This approach provides a number of ad-
vantages:
Exposure control
Analog gain
+24 dB (max)
60 dB (Typical)
Dynamic range
Signal to noise at
– SmOP technology is suitable for high volume
manufacturing
37 dB (Typical)

– SmOP can be plugged into a PCB mounted
flow soldered socket
50cd.m
2.8 V (analog supply)
1.8 V (digital supply)
Supply voltage
– SmOP can be mounted close to noisy RF
source as differential signalling used to
transmit data has good immunity from radio
interference.

The sensor outputs raw Bayer colorized data to
the STV0974 companion mobile processor.
STV0974 then performs all color processing and
exposure control functions before outputting the
data in an appropriate interface format like YCbCr,
RGB or JPEG.
