Error-free data transmission from -400 ppm to +400 ppm

Supports both negative and positive clock frequency offsets

Enables robust real-time digital communication

Abstract

We present an elastic buffer design that enables all-digital clock recovery implementation with free-running receiver clock featuring negative and positive clock frequency offsets. Error-free real-time data transmission is demonstrated from -400 ppm to +400 ppm.
