A design method of digital camera around a back illuminated 1024×1024 pixels EMCCD image sensor is proposed. A CPLD is adopted to generate the CCD driver timing and video processing timing. The EL7156C pin driver chip is used for standard EMCCD clocks

and a discrete circuit is used for EM clock. Adopting a CCD analog front-end chip VSP2566 with CDS function to sample and digitize the CCD output into 16bits digital image data. The design method of logic timing control

driver circuit

and video processing circuit is introduced. The digital camera circuit can output 16 bits digital image data simultaneously at the speed of 8 frames per second. Experimental results show that the optical dynamic range can exceed 70dB

and the remote programmable control electron multiplication can operate at the gain more than 0.1e/ADU. The design has used in the remote EMCCD imaging system

which can be applied in the low light level imaging area and radiation diagnosis field.
