Abstract: The CCD image sensor with electron multiplication is a great success in low-light-level detection and imaging applications. This paper analyzes control requirements of the TC285SPD EMCCD used in low-light-level imaging. Combining with the timing control demands of the analog front end AD9845B, a timing generator is implemented to drive the EMCCD by VHDL. The VHDL design and implementation process of the timing generator are presented. In development environment of the Quartus II, some simulation results of the system are given and have been analyzed in the end.
