This paper describes the design and application scenarios of digital phased array radar downlink data acquisition and reception systems,which are more and more requirements for the design of single board multi-channel synchronous acquisition and multi board cards synchronous acquisition.This article is based on the dual channel 14bit analog-to-digital converter AD9680 chip of ADI,and utilizes the JESD204B protocol to achieve inter chip synchronization with high transmission rate,strong anti-interference ability,and easy testing of deterministic delay.Through the design and processing of key signals,a data synchronization acquisition technology based on the JESD204B protocol for single board multi-channel and multi board cards is introduced,Solved the phase consistency problem of digital phased array radar downlink data.This technology has good scalability and can meet the needs of actual projects.
