A method of high speed and parallel CCD control signal detection and simulative sequential video signal output is presented in order to get a reasonable design and an application of space optics remote sensing system with high-performance multi-spectral TDI CCD image sensor. At the line readout and transfer period of 200s

48 clock drivers and 31 DC bias signals are analyzed and detected simultaneously. At the same time

the prepared image data are transmitted fast from disk array to video image generator which is composed of FPAG

D/A

amplifier and denoise circuit

through PCI-X and LVDS bus. Sequential and real-time output of diversified testing video images is realizes. It is shown with experiments that three simulative chromatic video signals at frequency of 6MHz and eight simulative panchromatic video signals at frequency of 12MHz are generated synchronously and reliably. The reference voltage of video signal is 8V and amplitude range is 0~1.7V. The design requests are met for the valid sampling time and signal stabilization.
