Typical application
USB webcam
This sensor may be used in conjunction with the STMicroelectronics STV0676 co-processor to
produce a low cost USB webcam.
In this application the co-processor supplies the sensor clock and uses the embedded control
sequences to synchronise with the frame and line level timings. It then performs the colour
processing on the raw image data from the sensor before supplying the final image data to the host
using the USB interface.
The voltage regulators on-board the sensor are used to control external bipolar transistors to derive
the supplies for the sensor and co-processor from the 5V USB supply. This approach eliminates the
requirement for more costly external voltage regulation circuitry.

The input USB supply is 5 V. The 3V3 digital regulator generates the supply for the sensor digital
part and the co-processor IOs. The 1V8 regulator generates the core supply for the co-processor.
