Synchronizing Multiple JESD204B ADCs for Emitter Position Location Reference Design

Description

A common technique to estimate the position of emitters uses the amplitude and phase shift data of a signal derived from an array of spatially distributed sensors. For such systems: it is important to guarantee a deterministic phase relationship between the sensors to minimize errors in the actual measured data. This application design will discuss how multiple Analog to Digital Converters (ADCs) with a JESD204B interface can be synchronized so that thesampled data from the ADCs are phase aligned.
