The ICX274 is a diagonal 8.923mm interline CCD solid-state image sensor with a square pixel array and 2.01M effective pixels. Progressive scan allows all pixels' signals to be outputted independently within approximately 1/15 second. The methodology of designing the Analog Front End (AFE) for ICX274 was presented. AD9923A was used as AFE. The functional block of AD9923A was discussed and how to set the control register was introduced. Compared with the circuit proposed by SONY, the design with simple hardware structure was low cost and high reliability. Tests show that the timing of the horizontal and vertical drivers met the requirements of the timing of ICX274, and could drive ICX274 to output analog video signal.
