Generating AVS SmartReflex core voltage, PMBus for K2E reference design

TIDEP0041

Design files

Overview

The K2E requires the use of AVS SmartReflex control for the CVDD core voltage. This design provides method of generating the proper voltage without the need for any software. The circuit is currently implemented on the XEVMK2EX.

Features
  • Provides the AVS SmartReflex Core voltage required by the K2E
  • Meets the 5% voltage requirement for CVDD
  • Operates using the VCNTL interface
  • No voltage converters needed for VCNTL interface
  • No software required for operation

A fully assembled board has been developed for testing and performance validation only, and is not available for sale.
