Abstract

This document describes the fast bring-up feature in AFE81xx family devices. Typically, an AFE bring-up with all Power Up Calibrations takes 4 seconds for an 8T8R Configuration. With pre-computed calibration results stored in AFE’s on-chip non-volatile memory the bring-up time can be reduced to less than 400ms. This feature is applicable in various scenario in munition applications where fast boot up time is required for the end system.
