The Research and Implementation of Data Acquisition Technology Based on ADS6445

摘要

In recent years, with the continuous development of the civil aviation industry and the continuous innovation and development of civil aviation technology, the aviation field presents an unprecedented development situation. The emphasis on civil aviation safety and information technology has risen to a new level. The multilateration technology based on centralized time service is highly praised by the civil aviation industry due to its high positioning accuracy and simple station deployment. Therefore, it is imperative to use this technology to develop multi-channel receiver. Data acquisition is the core of digital signal processing for multichannel receiver. As an indispensable preliminary work of digital signal processing, it plays a key and even decisive role in the entire system. Based on the requirements of the research project, this paper takes the 14 bit high-speed ADC chip ADS6445 as an example to study high-speed ADC data acquisition technology. This paper introduces the register configuration and realization method of ADS6445 in detail, and designs a high-speed data acquisition system to realize simultaneous acquisition and display of analog signals of multiple channels.
