Driving time sequence control method of CMOS detector

Abstract

A driving time sequence control method of a CMOS detector relates to the technical field of CMOS detector imaging control, solves the problems of image blurring and the like caused by the fact that the working state of an existing CMOS detector is easy to be abnormal, and an imaging controller comprises a power-on time sequence and SPI module, a training module, a data conditioning module, a driving time sequence module, a 422 communication and analysis module and a data transmission module. The power-on time sequence and SPI module is composed of a counter and a D trigger in a homologous clock domain. According to the driving time sequence control method, based on optimal driving time sequence signal position setting of training, it is guaranteed that the detector is located at a stable and reliable position when sampling signals in the detector, the working state is normal, and the phenomenon of instability caused by changes of the external environment such as the temperature is avoided. The time sequence reset signal is re-sampled and then output, the relatively constant phase relation between the time sequence reset signal and each driving control signal is ensured, the sampling metastable state in the detector is avoided, and therefore the application stability and reliability can be improved.

Description

technical field [0001] The invention relates to a driving sequence control method of a CMOS detector, in particular to a driving sequence control method of a CMOS detector applied by inputting a high-frequency differential clock. Background technique [0002] The CMOS detector needs to provide a reference clock from the outside first. In order to avoid the abnormal working state of the phase-locked loop (PLL) and affect the reliability, a high-frequency clock can be directly input. In order to control the working mode of the detector, the content of the internal SPI register is usually configured. In order to save configuration time, the SPI reading and writing frequency is usually set higher; in order to realize the normal operation of the detector, it is necessary to input multiple A driving and control signal; in addition, in the power-on and reset stages of the detector, it is also necessary to output a power-on reset signal and a timing reset signal. If the transition ...
