STV0502 数据手册 ( 数据表 ) - STMicroelectronics

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.

■ SERIAL BUS CONTROL

VIDEO
■ CORRELATED DOUBLE SAMPLING OF THE CCD SIGNAL
■ DIGITALLY CONTROLLED VARIABLE AMPLIFIER AND BLACK CLAMP LEVEL
■ 8 BITS PIXEL RATE ADC

AUDIO
■ MICROPHONE PREAMP WITH SWITCHABLE AGC (RANGE 34dB - 60dB) OR FIXED GAIN
