VS6552
1 OVERVIEW
1.1 Sensor Overview
The VS6552 VGA image sensor produces raw
VGA digital video data at up to 30 frames per sec-
ond. The image data is digitized using an internal
10-bit column ADC. The resulting 10-bit output
data includes embedded codes for synchroniza-
tion. The data is formatted and transmitted over a
fully differential link. The data is accompanied by a
qualifying clock that is transmitted over an identi-
cal fully differential link.
The sensor is fully configurable using an I²C inter-
face.
The sensor is optimized for high volume mobile
applications

Figure 1. Camera System Using STV0974
The VS6552 is an image sensor, it should be used
in conjunction with the STMicroelectronics
STV0974 companion processor. The coprocessor
and the sensor together form a complete imaging
system.
The sensors main function is to convert the viewed
scene into a data stream. The companion proces-
sor function is to manage the sensor so that it can
produce the best possible data and to process the
data stream into a form which is easily handled by
up stream mobile baseband or MMP chipsets.
The sensor supplies high speed clock signal to the
processor and provides the embedded control se-
quences which allow the co processor to synchro-
nize with the frame and line level timings. The
processor then performs the color processing on
the raw image data from the sensor before supply-
ing the final image data to the host.
