Video Surveillance Camera Front-end Solution Based on ADDI9020 and ICX692AQA

CCD image sensors in today’s video surveillance cameras require a dedicated driver chip to drive the CCD and an analog front-end to condition the CCD output signal.

ADDI9020* is a highly integrated CCD signal processor,
• Fully featured analog front-end circuit, including black level clamping, variable gain CDS and 12bit ADC.
• Programmable timing generator to provide all necessary clocks for the CCD, (RG, H clocks (5), V clocks (12)), sensor gate pulses, base clock and substrate bias control.
• 60MHz ADC.
• GPIOs (7) for system function.

*The ADDI9020 full manual can only be obtained with a signed NDA. Please contact your local ADI distributor or send us an e-mail at

This reference design is a complete analog front-end solution based on the ADDI9020 and latest CCD sensor ICX692AQA from Sony. The solution support up to 1280(H) x 720(V) @30Frame/s video format.
