    To meet the increasing demands of large mosaic CCD cameras from astronomical observation, an modularized CCD universal controller was developed. The modularization design is based on the principle that the system can be extended easily to drive multiple CCDs. Great efforts are exerted to reduce the system noise of the controller. A fully digital structure is chosen therefore the clocking and biasing can be tuned to control different kinds of CCDs and all the controlling data can be monitored remotely. With efforts, the system's readout noise reaches 2.61e-, dynamic range 16 bit, nonlinearity less than 1%, and these parameters meetthe criteria required for most of the astronomical observations for the-time-being. With this controller, a CCD camera is constructed to test a spectrogaph which is designed to work from 102 nm to 320 nm for space astronomical observation and the spectrums of helium and deuterium lines of the 121.5, 164, 193, 205, 218.6, 273.3 and 294.5 nm are acquired.
