Universal area array CCD timing sequence driven generator

Abstract

The invention relates to a universal area array CCD timing sequence driven generator. The universal area array CCD timing sequence driven generator comprises a bus interface module, a control module, an image timing sequence generation module, a perpendicular transfer timing sequence generation module, a master clock generation module and a high frequency timing sequence generation module. The bus interface module is connected with the control module and connected with the high frequency timing sequence generation module. The control module is connected with the image timing sequence generation module, the perpendicular transfer timing sequence generation module and the high frequency timing sequence generation module. The master clock generation module is connected with the high frequency timing sequence generation module and connected with the perpendicular transfer timing sequence generation module. The timing sequence generator designed through the method has high universality and flexibility, and in other words, the waveforms and the mutual relations of the timing sequences can be changed by modifying output values of all states; the number of output signals can be increased by increasing the bit widths of the output values; the time resolution can be improved by increasing the number of the states of waveform division.

Description

technical field [0001] The invention belongs to the application field of photoelectric sensing and relates to a general area array CCD timing drive generator. Background technique [0002] The CCD must be driven by the peripheral drive circuit to complete the generation, storage, transfer and output of the optical signal charge packet. For area array CCD, a complete drive circuit system is mainly composed of timing pulse generation circuit, clock drive circuit, DC bias circuit, signal preprocessing circuit, interface circuit and other parts. [0003] CCD drive timing is a set of periodic, relatively complex timing pulse signals with a specific time relationship. Accurate drive timing is the guarantee for the normal and stable operation of CCD devices. Therefore, how to design a correct and reliable CCD drive timing circuit becomes CCD. One of the key issues of application. [0004] It is difficult to design the timing generator of the high-resolution large area array CCD c...
