DESCRIPTION

The chip integrates the analog functions needed in a CCD Video Camera, more particularly for video conferencing purpose.

The CCD signal is sampled, amplified to a useful level and digitized by an 8 bits ADC. The gain of the amplifier and the black level clamp can be adjusted by a serial bus.
